AngularJS: Top Use Cases and Reasons to Opt for This Tool
By Ashish Kumar
AngularJS represents a structural framework for dynamic web applications. It is an open-source, JavaScript-based front-end web platform primarily developed by Google and a consortium of individuals and companies to solve many of the challenges faced in the development of single-page applications. AngularJSAngularJS offers flexibility in coding like no other framework due to its simple design architecture. In terms of simplicity, it helps beginners to get started and make improvements to their application projects easily. AngularJS also handles heavy web applications that are exceptionally well loaded with features and components. It allows you to use HTML as your template language and allows you to extend the syntax of HTML to clearly and succinctly express the components of your application. The data binding and dependency injections ensure that we do not need to write a big chunk of code which otherwise we would have ended in writing. And all happens inside the browser making it a perfect partner for any application. The next layer data binding frameworks gains popularity due to strong demand. The foremost known ones are: AngularJS KnockoutJS BackboneJS DurandalJS JavaScriptMVC AngularJS overview AngularJS is a platform and framework that uses HTML and TypeScript to build single-page client applications. The below diagram will give you fair idea of difference in traditional page life cycle vs Single page life cycle : AngularJS overviewThe AngularJS application is written using typescript. It introduces core and optional features when you import a collection of TypeScript libraries into your applications. The architecture of an AngularJS application is based on some fundamental principles.The basic building blocks are NgModules which provide the component compilation background. NgModules compile the related code into functional sets; a collection of NgModules define an AngularJS application. An AngularJS application often has at least one root module that enables bootstrapping, and usually has a lot more feature modules.We will not go into details as this is out of scope of this article but to give you better understanding of an AngularJS application ,let's look at below example where we are trying to calculate area of rectangle : <divng-appng-init="width=1;breadth=2"> <b>Area:</b> <div> Width: <inputtype="number"min="0"ng-model="width"> </div> <div> Breadth: <inputtype="number"min="0"ng-model="breadth"> </div> <div> <b>Area:</b> {{width * breadth}} </div> </div>This appears to be normal HTML, with some new markup. A file like this is called a Template in AngularJS. Once AngularJS launches the code, it uses the compiler to interpret and process this new markup from the template. The DOM that is loaded, transformed, and rendered is then called view. The Directives are the first kind of modern markup. We add special actions to items or attributes in the HTML. You would have noticed the new attribute ng-app which is a directive for initializing AngularJS apps automatically.AngularJS also defines an input element directive which adds additional behavior to the element. The directive ng-model stores / updates the value of the input field within / from a variable. Why AngularJS? AngularJS is backed by Google. This is a huge relief for developers to operate on a stable code base that will offer the application maximum support. it's a stable platform to focus on. Many frameworks are nowadays a pure bundling of existing resources. They are an integrated group of tools but they are not very elegant. AngularJS is the next generation platform where each tool was built to function in an integrated manner with any other tool. Please find below some reasons why AngularJS is considered as best among its competitors: MVC inbuilt support Most frameworks enforce MVC by asking you to break your app into MVC components and then allow you to write code to re-string them. This is a lot of work. As a developer we have to just split the framework into MVC components and leave everything to AngularJS for taking care. Declarative User Interface AngularJS uses HTML to describe the user interface within the program. HTML is a more concise and less complex declarative language than the procedural interpretation of the JavaScript interface HTML is also less brittle to reorganize than a JavaScript-written GUI, so things are less likely to break. And when the view is written in HTML, you can put in a lot more UI developers. Data models are POJO The POJO acronym for plain old java objects are being used as data models in AngularJS and it works without superfluous functions getter and setter. You can include and change properties straightforwardly and circle over objects and exhibits voluntarily. Your code will look a lot of cleaner and progressively instinctive, the way mother nature expected. Behaviors with Directive Directives are the way AngularJS brings added functionality to HTML. Imagine a world in which HTML has so many rich elements ( e.g. < accordion>, < grid>, < lightbox>, etc.) that we never have to manipulate a DOM to simulate them.To get some functionality out of the box, all that our app needs to do is assign attributes to items. Flexibility with filter Before displaying data on UI, filters filter the data and may include anything as simple as formatting decimal places on a list, reversing the order of an array, filtering a parameter-based array, or implementing pagination. Filters are designed to be stand-alone features, similar to instructions, independent from your device, but concerned only with data transformations. Less code All the points you have received up to now mean you 're getting to write less code. No need to write your own MVC pipeline. The view is described using more succinct, HTML. Without getters / setters, data models are easier to write. Data-binding means you don't have to manually insert data into the view. Also the directives are different from the software code, they can be written in parallel with limited integration issues by another team. Filters let you manipulate view level data without changing controllers. Unit testing ready The definition of AngularJS would be incomplete without speaking of its readiness for unit test. Dependency Injection (DI) links the whole of AngularJS together. Agular's unit tests will use dependency injection for unit testing .It mocks the data and injects into server. In reality, AngularJS already has a mock HTTP provider for controllers to insert fake server responses. It beats the more conventional way web apps are checked by creating individual test pages that activate a single feature and then communicate with it to see if it is working. Google assisted, and a great community of growth. Supported by IntelliJ IDEA and Visual Studio .NET IDEs. Limitations AngularJSis not a magic bullet. Some of its drawbacks are the backsides of its positive points, some of which are intrinsic to JavaScript inefficiency that could not be solved even with the strongest derivatives of its limitations are listed below: AngularJS is broad and complicated. With multiple ways to do the same thing, it's hard to tell which way is best for a particular task. Mastering AngularJS at the "Hello World" level takes significant effort. Different developers' coding styles and habits can complicate the integration of different components into a complete solution. When the project expands over time, you will most likely need to throw away current implementations and build new ones using different approaches. AngularJS implementations are poor in scale. More than 2,000 watchers will seriously lag behind the UI. This limits the complexity of your AngularJS forms , especially large data grids and lists. Best use cases of AngularJS If you want to build smart lightweight applications, AngularJS is your best bet. This TypeScript-based framework helps you to build interactive SPAs that are safe, maintainable, and easy to check. Some of the popular use cases for AngularJS are as follows: YouTube PlayStation three app for video streaming Anyone who likes to play video games would not have skipped the PlayStation 3 version of YouTube. Considering the vast popularity of YouTube, a structure will be needed. Because Google owns AngularJS, it has been leveraged to introduce a brand-new version of YouTube on PlayStation 3. The flexible architecture has helped Google reinvent the PS3 experience by replacing the traditional operating method with a fully new one. They replaced mouse movements with basic keystrokes. With AngularJS usability, the features of native apps like YouTube PS3 can be extensively leveraged.AngularJS has made a greater contribution in playback video and smooth scrolling on the YouTube PS3. It's the latest ultra-modern and seamless experience of AngularJS, experienced by the crowd of gamers. eCommerce applications like T-Mobile T-Mobile discovered that its customers had to wait for content to be loaded while connecting to the app. So, to make it quicker and less complicated, they used AngularJS server-side rendering to reduce the time. They also used AngularJS so that they could use HTML parsing for search engine purposes. This leading telecommunications leader has had tremendous success in their eCommerce app, which has generated a phenomenal search engine traffic. With AngularJS, the application interface has been revamped and turned into a smooth and powerful app. Real-time Data Application like weather.com Weather.com is one of the most popular real-time weather update websites. The credit for its success is given to AngularJS 's modular functionality of modules and directories that enable you to use the features of the app on mobile and smartphone devices. The framework enables developers to build customizable widgets based on the device's specific needs. Using real-time data and dynamically presenting it made it available on the Web using AngularJS technology. What projects don’t need AngularJS AngularJS is super heroic, but there are situations where you can't use AngularJS. Websites with Static Content Small websites with lower targets and static content. These types of websites are better built with limited technical stacks and do not need to be used by AngularJS, as the technology will only add extra pieces of code that are not required by the website or a specific project. Example: landing pages, educational websites, event pages, etc. Limited Resources and Startups AngularJS is not a good idea to start with for small teams and limited resources. AngularJS needs the skillful tools necessary to solve fast problems in large-scale projects. Technology should also not be used for small projects; it can be developed with other available frameworks and does not require much technological facilitation. Game Apps and Heavy Analytical Apps AngularJS is not a gaming app. Other frameworks, such as React, can be used to build a highly interactive UI in games. AngularJS tests every document object model before it changes its position. It is not recommended to use AngularJS in any app which require strong complex mathematical analytics mostly which is used in gaming. Popular web apps built with AngularJS Sharing a list of some of the renowned web applications that are driven by a versatile and robust AngularJS framework: The Guardian The Guardian is a leading designer and publisher, winning a variety of competitions in these fields. The Guardian website UI is created as an AngularJS app.Guardian.com PayPal Papal is one of the world's largest Internet payment firms. This is another one of the big websites that use AngularJS.Paypal.com JetBlue JetBlue is one of the most famous airline companies in the United States as the online airline portal. The new edition of the JetBlue website uses AngularJS.Lego Lego is one of the world's leading producers of play materials. Its products are traded global and can be virtually explored at www.LEGO.com.Lego.com NetflixNetflixNetflix is an American MNC entertainment company.

How to set up local environment for Angular 9
By Ashish Kumar
This article is a guide to building a solid atmosphere to facilitate the best Angular learning and work experience. Let us make sure that we have the best possible development experience and do not run into common issues with the development environment. Facing issues with the development environment is one of the biggest obstacles for someone new to the Angular ecosystem, perhaps even more so than the reactive concepts themselves. It is therefore crucial to get the environment correctly set up right from the start. The development environment must be easily upgradeable and create minimal issues over time due to things like semantic versioning. In this guide, I discuss how to set up your Angular Development environment using the Angular CLI method. I will talk about the prerequisites, how to install a CLI, how to build an initial workspace and starter app, and how to run the app locally to test your setup. Prerequisites You should be familiar with the following to use the Angular framework: HTML, CSS, JavaScript, Typescript Knowledge of TypeScript is helpful, but not essential. Development Environment Node NPM Editor-Visual Studio Code Angular CLI Setting up a Node Development Environment In this case, Node.js is used to create the backend of your app and can be replaced with any server-side technology you like, such as PHP, Ruby, or Python. However, Angular does not rely on Node.js, except for its CLI tool and for downloading NPM packages. To set up the best possible development experience, and if you do not have node yet installed: please visit the nodejs.org website and install the most recent version of node. Please make sure that you use the long-term support version (LTS) instead of the latest version.Open a browser, type https:/nodejs.org/en/download/, and click the Windows Installer button. You will seethe LTS displayed along with the current version of the node. Go ahead and download the recommended or current version of the node. We will be using node for frontend tooling purposes and for running our development server. For this specific purpose, you would be likely to run into fewer issues if you employed the latest version. However, if you already have node installed (any version), there is a far better way to upgrade your node version than to run an installer.Instead of overwriting your current version of node with the latest one, let us use a simple command line tool that easily allows switching node versions. There are several advantages to using the command line tool: It is very useful to be able to quickly change node versions if, for example, there are multiple projects to be maintained on the same machine, and each project needs different node versions. With this tool, it will be much easier to upgrade to newer versions of the node in the future – we will not have to run the installer again on your machine. So, let us make sure you have at least some version of the node installed on your machine before you start. To check your version, run node -v in a terminal/console window. NPM package manager NPM is the Node Package Manager. This is a list for hosting node packages. It has also been used in recent years to publish front end packages and libraries such as Angular, React, Vue.js and even Bootstrap. Angular, the Angular CLI, and Angular apps depend upon features and functionality provided by libraries that are available as npm packages. To download and install npm packages, you need to have a npm package manager. The npm client command line interface is used to access NPM package manager which gets installed with node js. To check that you simply have the npm client installed, run npm -v during a terminal/console window. npm -v v5.6.0 Install Angular CLI Angular CLI is the official resource for beginning and operating with Angular projects. It saves you from the mess of complicated configurations and builds resources like TypeScript, Webpack, and so on. Like most modern frontend tools these days, Angular CLI is also built at the top of Node.js. Node.js is a server technology that allows you to run JavaScript on your server and build server-side web applications. However, Angular is the front-end code, so even if you need to install Node.js on your development computer, it would just be for running the CLI. When you create your production software, you won't need Node.js because the final bundles are static HTML, CSS, and JavaScript can be supported by any server or CDN. If you are building a full-stack web application with Angular, you may need Node.js to create the back end if you want to use JavaScript for the front end and back end. Deploy the Angular CLI Open the terminal and type below command with help of NPM to install angular CLI: npm install -g @angular/cli Some useful commands using angular CLI You can run many commands once you download Angular CLI, such as: To check version of CLI: $ ng version To add support to your project for an external library: $ng add To compile the Angular app in the output directory called dist.or in the output path defined; should be executed from inside a working space directory: $ng construct To retrieve or set Angular configuration values: $ng configure To open the official Angular Documentation (angular.io) in the browser and searches for a keyword: $ng doc To generate and/or change schematic-based files: $ng generate To list the commands available and their brief descriptions: $ng help To run lining tools on the Angular device code in the project folder: $ng lint To build a new workspace and an initial Angular app: $ng new To run a custom target set for your project: $ng run To develop and support your request, restore on file changes: $ng serve After you have installed Angular CLI, you will need to run one command to create a project and another to support it using a local development server to play with your program. Creating workspace and initialization of angular application: You can use Angular CLI to create your first Angular project by executing the below command in your command line interface: Step 1: Navigate to project directory $ cd ~/Dev/ (Go to your local directory Dev) $mkdirmyProject(Create myProject directory in dev folder) $cd myProject(navigating to myProject folder) Step 2: Creating an Angular app $ ng new helloworld The command ng new will prompt you to include default a feature in the initial request. Usethe Enter or Return key to acknowledge the defaults. Note: ‘Helloworld’ is the name of this project. Of course, you can select any appropriate name for your project. Because this is our initial set up, I'mgoing with‘hello world’ as a name for the front-end application. Step 3:Navigate to project and run local server $ cd /path/to/your/newly/created/app/ Like $ cd ~/Dev/myProject/helloworld/ $ ng serve –open That will launch http:/localhost:4200/ * Note: ng serve command launches a server, searches for changes to your files, and rebuilds the software when you save changes * Step 4: Edit project Open file in dev/myproject/helloworld/src/app/app.component.ts: Edit the file and make some changes and save it. Changes will be highlighted: Within app root (app root is in /myproject/helloworld/ for our app,), Run: ng serve –open or just navigate tohttp:/localhost:4200/ . The web UI will reflect the changes. With ng serve still running, make and save a new change in app.component.ts: You will be surprised to see the changes automatically reflected in http:/localhost:4200/ Step 5:Build app and get ready for deployment $ng build This command creates a new folder in your app root named "/dist/" which is your entire package, compiled and ready for shipment. Nice Flags optional: Prod this creates a version of your app ready for production output-path /to / your / path/ this changes the default path to create your Angular files output-hashing none remove additional hash on your file nameConclusion In this guide, we have gone through the steps to setting up a solid local environment to facilitate the best Angular learning and work experience. Following these steps, you will ensure that the development environment is easily upgradeable, minimizing the possibility of any issues arising over time due to things like semantic versioning. We have discussed how to set up your Angular Development environment using the Angular CLI method, the prerequisites necessary and walked through how to install a CLI, how to build an initial workspace and starter app, and how to run the app locally to test your setup. I hope this has been a useful guide and I wish you the very best Angular learning and work experience!

Installation Guide to Jenkins
By Ashish Kumar
Jenkins is a Java-based open-source automation tool with plugins designed for ongoing integration. Jenkins is used to constantly develop and test software projects that help developers to incorporate project modifications and make it simpler for users to achieve a new build. The Jenkins allows developers to quickly locate and resolve flaws in a code base and to automatically test their structures. Jenkins can be changed and expanded readily on all operating platforms and various devices, whether OS X, Windows or Linux. It immediately deploys code, produces test reports. During integration and continuous delivery, Jenkins can be configured according to the demands.System Requirements for Jenkins InstallationFollowing are the software and hardware requirements for installing Jenkins:Minimum hardware requirements:256 MB of RAM1 GB of drive space (although 10 GB is a recommended minimum if running Jenkins as a Docker container)Recommended hardware configuration for a small team:1 GB+ of RAM50 GB+ of drive spaceInstallation on WindowsYou must first install JDK. Jenkins promotes JDK8 only at this time. Jenkins can be installed when Java is running. The recent Jenkins package for Windows (presently version 2.191) can be downloaded. Click on the Jenkins exe file to unzip the file into a folder.To begin the installation click on "Next."To install Jenkins in another directory, click the "Change..." button. I'll hold the default choice in this instance and click on "Next."To begin the installation process, click on the "Install" button.The installation is being processed.When finished, you can finish the setup by clicking the "Finish" button.The URL http:/localhost:8080 will automatically be redirected to a Jenkins local page or the browser can be pasted.Copy and paste the password from the C:\Program Files (x85)\Jenkins\secrets\initialAdminPassword file for Jenkins unlocking. Click on the button "Continue."The suggested plugins or chosen plugins that you select can be installed. We will install the suggested plugins to maintain it easy.Wait for the complete installation of plugins.The next step is to build a Jenkins admin user. Click "Save and Continue." Please enter your information.To finish the Jenkins setup, click on "Save and Finish."To begin Jenkins, click on "Start using Jenkins."Below is the default page of Jenkins.Jenkins Installation on Linux/CentOS 7 systemMake sure that you are signed in as a user with sudo privileges before continuing this tutorial.The first step is to install Java, Jenkins being a Java application. To set up OpenJDK 8 package, execute the following command:$ sudo yum install java-1.8.0-openjdk-develJenkins does not currently support Java 10 (and Java 11). Make sure that Java 8 is the default Java version when multiple Java versions are installed on your computer.The next step is to allow the repository of Jenkins. To do so, use the following curl command to import the GPG key:$ curl --silent --location http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo | sudo tee /etc/yum.repos.d/jenkins.repoAdd your system's repository with:$ sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.keyUpon activation of the repository, install the recent stable Jenkins version by typing:$ sudo yum install jenkinsUpon completion of the installation, begin the Jenkins service with:$ sudo systemctl start jenkinsTo verify if it has been successful, check with below command:$ systemctl status jenkinsSomething like this you should see:Outputjenkins.service - LSB: Jenkins Automation ServerLoaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)Active: active (running) since Thu 2018-09-20 14:58:21 UTC; 15s agoDocs: man:systemd-sysv-generator(8)Process: 2367 ExecStart=/etc/rc.d/init.d/jenkins start (code=exited, status=0/SUCCESS)CGroup: /system.slice/jenkins.serviceFinally, allow the Jenkins service to start on system boot $ sudo systemctl enable jenkinsOutputjenkins.service is not a native service, redirecting to /sbin/chkconfig.Executing /sbin/chkconfig jenkins onOpening Firewall portIf you install Jenkins on a remote CentOS firewall-protected server, port 8080 is necessary. To open the required port, use the following instructions:$ sudo firewall-cmd --permanent --zone=public --add-port=8080/tcpsudo firewall-cmd --reloadSetting JenkinsOpen your browser and type in your domain or IP address followed by port 8080 in order to set your fresh Jenkins setup:http://your_ip_or_domain:8080Below screen will be displayed which prompts you to enter the admin password generated during setup:To print the password on your terminal, use the following instructions: $ sudo cat /var/lib/jenkins/secrets/initialAdminPasswordThe alphanumeric password should be 32 characters long, as shown below:Output 3226*****************************Copy your terminal password, paste it in the password field for the Administrator and click on Continue.On the next screen, you are asked if you would like to install or pick certain plugins. To begin the installation process instantly, just click on the Install suggested plug-ins box.When the installation is finished, the first administrative user is prompted for the setting. Fill in all the necessary data. and click the Save and Continue.On your next page, the URL for the Jenkins instance will be requested. An automatically produced URL will be added to the URL field.To finish the configuration, click the Save and Finish button to verify the setup.Finally, click start using Jenkins Button to start the process and the user we created in one of the past steps as admin user will log in Jenkins dashboard.You have effectively mounted Jenkins on your CentOS scheme when you have reached this point.Jenkins Installation on MacPrerequisiteA Mac machine with Mac OSX Yosemite or higher with admin accessInstallation of Java Development Kit on the machine.Access to Git, Svn, etc. remote repository.Download Jenkins installer.pkg file from Jenkins ' official website and get through the wizard setup.The jenkins setup wizard sets up a distinct Jenkins user on your system.We need to make some changes in the ‘Users & Groups’ section as well. Do follow below steps.Open ‘System Preferences -> Users & Groups’Click on the Lock icon located in the bottom left corner which reads, ‘Click the lock to make changes’. Enter your login password.Under the ‘Other Users’ section you may see the user without any name but with admin rights. This is our Jenkins user. Let's rename it.Right-click the empty user and select Advanced Options. This will show you all the details. Give the ‘Full name’ as Jenkins. Press OKClick on ‘Reset Password’. Enter a new password and make sure that you remember this.Now our Jenkins user is almost ready.This is just like another mac user with admin rights.Now restart your Mac machine and log in with Jenkins user with the password which you just reset.Click the lock to save the changes and restart the system to login with Jenkins user account.In localhost Jenkins resides at port 8080.Open your browser, go to localhost:8080 and make the original set-up, which consists of installing some plugins and creating account for safety purpose.Setting Jenkins as Launch agentJenkins operates by default as a daemon. A daemon is a non-interactive background that operates in the entire scheme and is not linked to a particular user.Much of CI runs simulators and other GUI apps, so another option is required. You can modify Jenkins as a launch agent to resolve this. On behalf of the user, a launch agent operates behind the scenes.You need to edit the settings folder and alter your place to begin rebooting automatically if you want to alter how the Jenkins process is started.Enter the below command to unload Jenkins as a Daemonsudolaunchctlunload/Library/LaunchDaemons/org.jenkins-ci.plistNext, migrate to the LaunchAgents folder the.plist file which defines how Jenkins will be running.sudo mv /Library/LaunchDaemons/org.jenkins-ci.plist /Library/LaunchAgents/Start the jenkins again and now it will run as launch agent.

How to Install Docker on Windows, Mac, & Linux: A Step-By-Step Guide
By Ashish Kumar
Docker is intended to benefit developers and system managers and makes it a component of a number of toolchains for DevOps (developers + activities). This implies that designers can concentrate their attention on writing code without worrying about the scheme that it will eventually run on. It also gives them the opportunity to take advantage of one of the thousands of programs intended to operate as part of their implementation in a container at Docker. Docker offers flexibility for the operational team and decreases possibly a smaller overhead footprint and lower overhead the number of devices required.Let’s now deep dive into installation steps for docker on different platforms.Install Docker on Windows The community version of Docker for Microsoft Windows is Docker Desktop for Windows.Download from Docker Hub. System RequirementsThe software and hardware requirements need to operate Client Hyper-V on Windows 10 effectively are:Software Requirements:Windows-10 64-bit system requirements: Pro, Enterprise or EducationWindows characteristics of Hyper-V and Containers must be activatedHardware Requirements:The support for virtualization of hardware-level Client Hyper-V in BIOS settings must be allowed with the 64-bit processor with second-level address translation (SLAT). Minimum 4 GB RAMTo run Docker Desktop, Microsoft Hyper-V is needed. The Windows installer Docker Desktop allows Hyper-V and restarts your computer if needed. VirtualBox no longer operates when Hyper-V is activated. All VirtualBox VM images are however maintained.The DOCKer VMs (including the default one generated during the installation of the Toolbox) are no longer started. VirtualBox The Docker desktop can not use these VMs side-by-side. You can still handle remote VMs using the docker.What is included in Installation?The installation of Docker Desktop consists of the Docker Engine, Docker CLI, Docker Compose, Docker Machine, and Kitematic. Docker Desktop containers and images are shared among all user accounts on the machines where they are installed. All Windows accounts are building and running containers using the same VM. Nested virtualization situations, such as operating Docker Desktop with VMWare or Parallels, might operate. See Running Docker Desktop in nested situations for more data.Installation steps To run the installer, double-click Docker Desktop Installer.exe to install Docker Desktop on Windows. The installer can be accessed from Docker Hub if you have not previously downloaded (Docker Desktop Installer.exe). It typically downloads to your download directory or can be executed at the bottom of your internet browser from the latest download bar.Follow the installation wizard directions for licensing, authorizing the installer and proceeding with the installation. If advised, authorize your system password during the installation of the Docker Desktop Installer. The networking elements, connections to the applications of Docker and the management of Hyper-V VMs need to be privately accessible.Click Finish in the setup window and launch the application Docker Desktop.Start Docker DesktopAfter installation, Docker Desktop will not begin automatically. Search for Docker and select the search outcomes for Docker Desktop.If the whale icon remains stable in the status bar, Docker Desktop is up and running and can be accessed from any terminal window.You also get a pop-up message with the next steps, as well as a link to this documentation, after the Docker Desktop app is installed.When you're done initializing, click on the whale icon in the Notifications region and pick About Docker to check that your recent version is available.Install Docker on MacThe very first step is to download the Docker Toolbox for Mac. Get the downloadable link- Download from Docker HubSystem RequirementDocker Desktop for Mac starts only when all these requirements can be met:Mac hardware must be 2010 models or newer, including Extended Page Tables (EPT) and Unrestricted Mode, with Intel hardware to provide memory management unit (MMU) virtualization. This support can be checked to see if the following command is being run on your computer: sysctl kern.hv_supportmacOS Sierra 10.12 and newer versions of macOS are endorsed. The upgrade to the newest version of macOS is recommended.VirtualBox (incompatible with Docker Desktop on Mac) before version 4.3.30 must not be installed. It's alright if you have a newer VirtualBox version installed.Installation stepsDouble-click Docker.dmg and drag the whale Moby to the application folder to open the installer.In the Applications directory, double-click Docker.app to launch Docker. In the instance below, the applications folder is in the Grid view modeYou are led to allow Docker.app with your system password after starting it. Privileged access is required to install Docker app connections and networking elements.The whale in the top status bar shows that Docker runs from a terminal and is available.You will also get a success message, with the next steps and a link to this documentation, if you have just installed the app. To reject this pop-up, click on the whale in the status bar.To get Preferences and other options, click on the whale (whale menu).To check that you have the latest version, select About Docker.Notes:Getting started provides an overview of Docker Desktop for Mac, basic Docker command examples, how to get help or give feedback, and links to all topics in the Docker Desktop for Mac guide.Troubleshooting describes common problems, workarounds, how to run and submit diagnostics, and submit issues.Install Docker on LinuxLet’s use a Ubuntu example to begin installing Docker. If you don't already have it, you can use Oracle Virtual Box to install a virtual Linux example. A straightforward Ubuntu server mounted on the Oracle Virtual Box is shown in the following screenshot. There is an OS user called a demo defined with full root access to the scheme:Step 1 − We must first make sure you have the correct version of the Linux kernel running before installing Docker. Only version 3.8 or greater is intended for Docker on Linux kernel. We can do this with the instructions below.Uname: The system data for the Linux system is returned by this method. This method will return the kernel name, kernel release, kernel version information on the Linux system.uname -aa − Used for ensuring the return of the system data.Step 2 − You need to install packages from the internet onto the Linux system via the following command, the recent packages can be updated to the OS.apt-get Optionssudo− The sudo command is used to make sure the command runs with root access.update− Update option ensures that all packages on the Linux system are updated.sudo apt-get update Step 3- The next step is to install the certificates needed to later download required Docker packages for a job with the Docker site. The following command can be used.sudo apt-get install apt-transport-https ca-certificates Step 4− Adding fresh GPG key will be the next step. This key must guarantee that the required packages for Docker are all encrypted.This command is intended to download the key from hkp:/ha.pool.sks-keyservers.net:80 and add it to the adv keychain by means of the ID58118E89F3A912897C070ADBF76221572C52609D. Please note that to download the necessary Docker packages, this specific key is needed.Step 5 − Next, you need to add the appropriate site to docker.list of the apt package manager, depending on the version of Ubuntu which you hold, to allow it to detect and download the Docker packages from the Docker site.Precise 12.04 (LTS) ─ deb https://apt.dockerproject.org/repoubuntu-precise mainTrusty 14.04 (LTS) ─ deb https://apt.dockerproject.org/repo/ ubuntu-trusty mainWily 15.10 ─ deb https://apt.dockerproject.org/repo ubuntu-wily mainXenial 16.04 (LTS) - https://apt.dockerproject.org/repo ubuntu-xenial mainecho "deb https://apt.dockerproject.org/repo ubuntu-trusty main” | sudo tee /etc/apt/sources.list.d/docker.listStep 6 –The next step is to update the packages on Ubuntu scheme with the apt-get update command.Step 7 ‐ if we want to make sure that the package manager points towards the correct repository then we can do this by issuing the apt-cache command.apt-cache policy docker-engineStep 8– Edit the update command apt-get to guarantee that all local system packages are up-to-date.Step 9- The Linux-image-extra-* kernel packages that allow the user to use the aufs storage driver are required for Ubuntu Trusty, Wily and Xenial. The newer variants of Docker use this engine.The following command can be used:sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtualStep 10− Installing Docker is the final step and this can be done with the following command:sudo apt-get install –y docker-engineHere, apt-get utilizes the installation feature to download and install Docker from the Docker page. The Docker engine is the official package for Ubuntu based devices by the Docker Corporation.The docker running version can be checked by running below command:docker version

Tableau Vs QlikView
By Ashish Kumar
What is Tableau?Tableau stands as the most powerful and fastest-growing data visualization tool which is being used in the Business Intelligence Industry. Its basic funda is to simplify raw data into a format that can be easily understandable. Data analysis has become very quick with Tableau and the dashboards and worksheets are the forms of visualization that are being created.The best part is that Tableau is a market-leading BI tool as well as the most trending tool used to visualize and analyze the user's data in a very easily digestible format.It also enables the user to work on live data-set and spend quality time on data analysis rather than data wrangling.Usage of Tableau software are listed below:They are used to translate queries into visualization.Managing metadata is also feasible through Tableau.It can even import data of all sizes and ranges.In the case of the non-technical user as well as Tableau acts as a lifesaver as it offers the facility to create ‘no-code’ data queries.What is QlikView?When we talk about the most flexible Business Intelligence platform for turning data into knowledge then Qlikview comes into the picture. There are more than 24,000 organizations worldwide have enabled their users to easily consolidate, search, and analyze visually all their data by using QlikView.List of the top companies using QlikViewCompanyWebsiteCountryRevenueCompany SizeRed Hat Incredhat.comUnited States>1000M>10000Centerstone of Tennessee,Inc.centerstone.orgUnited States50M-100M1000-5000Robert Walters Plcrobertwalters.comUnited Kingdom>1000M1000-5000Nigel Frank International Limitednigelfrank.comUnited Kingdom200M-1000M1000-5000Axtriaaxtria.comUnited States10M-50M500-1000The wide scope of this software lies in its simplicity of usage. The creation of dashboards for analytical purposes is done by its reporting tools.The era of modern analytics truly began with the launch of QlikView. It actually revolutionized the way organizations lets its user create data with the intuitive visual discovery that put business intelligence in the hands of more people than ever.Enterprise-scale analytics is also being performed with utmost ease and credibility.Usage of Qlikview software are listed below:Flexible Business Intelligence platform for converting data into knowledge.Consolidating, searching and visually analyzing data with simplicity.Even data discoveries in order to support decision making for end-users in the business.Key Difference between Tableau and QlikViewA quick view of the difference between Tableau and QlikViewFeaturesTableauQlikviewPerformanceProcesses data slower than QlikviewCombines large and complex data at a faster rateSpeedSlow in the data processingData processing and accessing is fasterCostCheaperBit costlyBig data supportGoodAverageMultidimensional CubesGoodLimitedVisualizationSimple and interactiveExcellentCustomizationSimpleComplex toolLet’s understand the differences brieflyEase of UseEverybody can analyze information with intuitive products for drag & drop. No programming, only insight. The user can easily create their own perception using various objects and it's easy to use because of a well designed GUI interface. Tableau offers a storytelling feature that can allow us to create a presentation using data points that are available. It does not provide a feature to search content across all the user's dataThe best quality of Qlikview is it's easy to use the feature and even exploring the hidden trends.QlikView offers an associative technology that enhances the capacity of the presentation. This feature helps companies understand hidden links between data points. In the case of searching any data, we just need to type the word in the search box resulting in instant and It also shows in-depth connections and relationships across the data. At times it becomes difficult for users to design their own views due to properties that are menu-driven.Ease of LearningTableau has community and resources which are actively engaged. The drag & drop application even makes it very easy to learn for the end-users.QlikView also has actively engaged community and resources which ultimately helps the user learn this software in the best possible way.CostTableau: Here are Tableau’s new monthly prices: Tableau Desktop Personal, $35; Tableau Desktop Professional, $ 70; Tableau Server, $35; and Tableau Online, $42. Under the old model, a license, with annual maintenance, costs $999 for Desktop Personal and $1,999 for Desktop Professional. The server starts at $10,000 for 10 people, and Online is $500 per user per year.Qlikview: The personal edition in Qlikview is absolutely free with a limitation of no feature for document sharing. Per named user license is $1,350 and $15,000 for a concurrent user. Per Server license cost around $35,000. Additionally we require to pay $21,000/server in case of PDF distribution service; $22,500 for SAP NetWeaver connector.Might even require upgradation of RAM if the concurrent users are larger in number.Data VisualizationTableau is one of the industry's leading instruments for data visualization. Today, companies are investing more in information segmentation, clustering, and stronger analysis. It offers a user-friendly interface that enables even non-technical users to generate tailored dashboards rapidly and easily to give significant perspectives in a wide range of company data.QlikView, on the contrary, offers normal report creation characteristics, visualization templates, configurable graphs, and customized opinions that assist provide an interactive report in real-time. All the visualizations and data sets are shown as a quick reference when QlikView is in use. Qlik's product provides an in-memory engine that can view patterns and produce associative analytics that alone can not be achieved with SQL. The In-Memory Engine is able to integrate with diverse information source variants and create a unified dashboard that shows analyses, KPIs and metrics of our concern.Connectivity with Other tools/ Language or DatabaseTableau integrates successfully with a wide range of data sources which includes the spreadsheets, CSV, SQL databases, Salesforce, Cloudera Hadoop, Firebird, Google Analytics, Google BigQuery, Hortonworks Hadoop, HP Vertica, MS SQL Server, MySQL, OData, Oracle, Pivotal Greenplum, PostgreSQL, Salesforce, Teradata, and Windows Azure Marketplace. It can also coordinate with sources of Big data as well.Qlikview also integrates with high range of data sources like Amazon Vectorwise, EC2, and Redshift, Cloudera Hadoop and Impala, CSV, DataStax, Epicor Scala, EMC Green Plum, Hortonworks Hadoop, HP Vertica, IBM DB2, IBM Netezza, Infor Lawson, Informatica Powercenter, MicroStrategy, MS SQL Server, My SQL, ODBC, ParAccel, Sage 500, Salesforce, SAP, SAP Hana, Teradata, and many more. In this case, API integration can be used to connect with R. It can also readily connect with Big data sources.DeploymentSince tableau does not have their own data warehouse hence they have to generate layers while connecting with data set. The deployment becomes easier here since it needs more structured data.QlikView has its own data warehouse with an additional feature of scripting which acts as a feature in the cap leading to the use of multilevel layers in its deployment. QlikView is readily deployable and configurable and starts producing excellent reports immediately after the installation. An additional feature involves enabling interactive queries and creation of reports—a technology which is not found in other products since this product does not use cubes; hence loads all the tables and charts found in the memory. Both 32 and 64 bit can be used for the development. Data modeling becomes easier because of associative technology.SpeedIn the case of Tableau the speed varies based on two parameters, first being the RAM and second being the source's database. Tableau makes it extremely effective to produce in a matter of minutes of interactive views and reports. Tableau can also speed up the entire process since it enables online and offline report sharing. In Quikview the Speed is dependent on only the source's RAM.QlikView offers quick assessment, outcomes, and allows for much quicker decision-making in comparison to traditional techniques.Valuable Insight GenerationTableau has an excellent storytelling feature that helps the user to create effective presentations, using the available data sources.In Qlikview the Associative technology makes it more impressive and it also helps to read association between variables readily. This unique feature sometimes even benefits businesses to understand the hidden relation between the data points.MobilityTableau is readily available on all devices and can be accessed via the internet. We can even use it on our laptop, tablet or smartphones as well.QlikView is independent of any device thus we can easily access it from anywhere hence decision making becomes much prompt and quicker as compared to the traditional methods of data visualization.SecurityTableau provides excellent security features and it is highly handled by Tableau server. It is indeed a modern enterprise analytics platform that enables the users to avail the self-service analytics at scale with proper governance. Security is the first and foremost critical part of a data and content governance strategy. It's server actually provides comprehensive features along with deep integration to address all the aspects of enterprise security present. Tableau also renders the organizations in promoting trusted data sources for all users, so the right data is used to make the right decisions within seconds.PerformanceWhen compared with Qlikview, Tableau generates the output slower since it uses the cubing technique for data visualization. QlikView seamlessly combines all sizes of datasets hence are quicker when compared with Tableau.ScalabilityQlikView is a lot more scalable than Tableau. The Qlik Sense applications can be easily scaled especially while dealing with big data. But we cannot deny the fact that both the vendors handle a huge amount of data successfully. In Fact, most of the organizations do not produce the amount of data that both these can handle individually.Big Data SupportTableau has good support for Big data as compared to Qlikview.CustomizationSimple drag and drop features are available in Tableau. Qlikview is Complex tools when compared with Tableau.ConclusionIn brief, the reply to the question:' Which is the best tool for data visualization? It's pretty subjective. Users find out the demands of their business or their projects, which is a matter of personal preference. In both Tableau and QlikView, all the points listed above in this blog illustrate the possible regions where consumers can assess and comprehend their possibilities and then decide in an informed fashion which ones to use.Want a career in Tableau and QlikView? Then taking up training in Tableau and QlikView would be an added advantage.

The Architecture of Power BI
By Ashish Kumar
The main element of the drive to be agile, competitive, and efficient is business intelligence. As companies develop, the regular generation of information becomes very hard to handle. This, in turn, generates a road-block for data-driven businesses that want to use their data to drive company decision-making.In addition, the siloing impact and biased reporting structures across companies generate a scenario where decision-makers are compelled to make choices based on information that is partly accurate.This is why smart business systems are largely embraced. Establishing an analytical system to efficiently analyze data helps a company find helpful information, propose conclusion and promote improved decision-making. With its demonstrated technology track record, Microsoft has come to the fore with the implementation of its convincing analytics instrument, Power BI. This report authoring tool enables businesses to readily visualize and analyze their business information to transform their activities. Here in this article, we will see various components included in Power Bi architecture. This guide will help you in installing Power BI.Microsoft Power BI ArchitecturePower BI architecture consists of four steps. Let's look at them in detail:Sourcing DataTransforming InformationReport & PublishCreating a Dashboard1. Sourcing Data: Power BI can supply information from a wide range of internet facilities and file kinds. The information can be imported into Power BI or a live service link can be established to receive the information. If you import a Power BI file, it limits the compressed data sets to 1 GB. If the information set exceeds 1 GB, then the direct query may be used. For big information sets, there are two other choices. Power BI premium Azure analytics servicesList of Data Sources supported in Power BIFiles:Excel, XML, JSON, Text/CSV,Folder and SharePoint FolderDatabase:SQL Server Database, Access Database, SQL Server Analysis Services Database, SAP HANA Database, SAP Business Warehouse server, Amazon Redshift, Impala, Google BigQuery (Beta), Snowflake,Oracle Database, IBM DB2 Database, IBM Informix database (Beta), IBM Netezza (Beta), MySQL Database, PostgreSQL Database, Sybase Database, Teradata DatabaseAzure:Azure SQL Database, Azure SQL Data Warehouse, Azure Analysis Services database (Beta), Azure Blob Storage, Azure Table Storage, Azure Cosmos DB (Beta), Azure Data Lake Store, Azure HDInsight (HDFS), Azure HDInsight Spark (Beta)Online Services:Power BI service, SharePoint Online List, Microsoft Exchange Online, Dynamics 365 (online), Dynamics 365 for Financials (Beta), Common Data Service (Beta), Microsoft Azure Consumption Insights (Beta), Visual Studio Team Services (Beta), Salesforce Objects, Salesforce Reports, Google Analytics, appFigures (Beta), comScore Digital Analytix (Beta), Dynamics 365 for Customer Insights (Beta), Facebook, GitHub (Beta), Kusto (Beta), MailChimp (Beta), Mixpanel (Beta), Planview Enterprise (Beta), Projectplace (Beta), QuickBooks Online Other:Vertica (Beta), Web, SharePoint List, OData Feed, Active Directory, Microsoft Exchange, Hadoop File (HDFS), Spark (Beta), R Script, ODBC, OLE DB, Blank Query2. Transforming information:After the information is imported into the Powerbi system, power bi offers a preview window for selecting columns or entities. There are many transformation choices available to perform the job if you need to edit the query.3. Report & Publish:We are prepared to produce reports after sourcing and editing the information. Reports are data visualization with filters and slicers in the form of graphs, charts and pie charts. A lot of custom visualization is also available. We can publish them to power bi facilities after generating reports. You can also publish them on the energy bi server assumption.4. Creating a Dashboard:We can create dashboards after publishing reports to Power BI services by pinning the individual elements or by pinning the page of the live report. The visual maintains the filter setting chosen when the report is saved when pinning the individual components. By choosing slicers and filters, pinning the Live Report page enables the dashboard user to communicate with the visual.Components in Power BIThere are four major components in Power BI which play an important role in delivering Power BI capabilities- 1. Power BI Desktop:Power BI Desktop is free software that allows you to connect, convert and visualize your information on your local desktop. You can connect to various distinct information sources with Power BI Desktop and combine them (often called modeling) into a data model that allows you to create graphics and collections of images that you can share with other individuals within your organization as records. Most users working on Business Intelligence projects use Power BI Desktop to generate reports and then use Power BI to share their reports with others.2. Power BI Gateway:The on-site Power BI gateway can be used to maintain your information fresh by linking to your on-site information sources without moving the information. It enables you to query big datasets and take advantage of current investments. By linking to your on-site information sources without the need to transfer the information, you can keep your information fresh with the on-site gateways. Request big datasets and take advantage of current investments. The gateways provide the flexibility you need to satisfy your organization's individual requirements and needs.3. Power BI Mobile Apps:You can remain linked to your information from anywhere using Power BI mobile applications. For Windows, iOS, and Android platform, Power BI applications are accessible.4. Power BI Service:This is a cloud service for publishing Power BI accounts and visualization of information. It allows designers and BI experts to generate and distribute extremely formatted, pixel-perfect reports alongside their interactive Power BI content, becoming the first cloud BI solution combining the energy of self-service BI with traditional Enterprise BI scenarios ' requirements and capacities.There are other components as well which we should understand to get benefits of advanced capabilities of Power BI.5. Power Query:Mashup data and instrument for conversion. You can connect to many distinct information sources with Power Query in Power BI, turn the information into the form you want, and be able to generate reports and ideas rapidly. Power Query functionality is given in the Power Query Editor when using Power BI Desktop. Power Query is made available in Power BI Desktop through Power Query Editor. To launch Power Query Editor, select Edit Queries from the Home tab of Power BI Desktop.6. Power Q&A:Natural Language Question and Reply Engine. Sometimes asking a question using natural language is the fastest way to get a response from your information. The Power BI Q&A function allows you to use your own phrases to explore your information. Q&A is discussed in distinct papers in the Power BI mobile applications and Q&A with Power BI Embedded.7. Power Map: 3D Geospatial Data Visualization Tool.8. Power Pivot:Power Pivot is an element that models information in memory that allows highly compressed data storage and incredibly quick aggregation and calculation. It is also accessible as part of Excel and can be used within an Excel workbook to build a data model. Power Pivot can load information on its own, or Power Query can load information into it. It is highly comparable to the tabular model of SSAS (SQL Server Analysis Services), which is like a Power Pivot server-based variant.9. Power View:Power View is an interactive visualization instrument that offers a drag-and-drop interface for users to quickly and easily create information visualizations in their Excel workbooks (using the Power Pivot data model).10. SSRS Reporting services 2016:The integration between SQL Serb Reporting and the Power BI Services takes SSRS tiles to a Power BI dashboard with planned SQL Server Agent updates. This integration gives you the tile from SSRS reports. Integrating SSRS reports into the Power BI service will generate a connection to comprehensive SSRS reports from the Power BI dashboard.Clusters in Power BI Architecture The Power BI service is based on Azure, the cloud computing platform of Microsoft. Power BI is currently being deployed in many data centers around the world–there are many active deployments made available to customers in the regions served by those data centers, and an equal number of passive deployments serving as backups for each active deployment.Each deployment of Power BI comprises of two clusters–a cluster of Web Front End (WFE) and a cluster of Back End. The following picture shows these two clusters :1. WFE Cluster:The WFE cluster manages the original Power BI link and authentication process using AAD to authenticate customers and provide tokens for subsequent Power BI customer links. Power BI also utilizes the Azure Traffic Manager (ATM) to guide customer traffic to the closest datacenter, which is determined by the client's DNS record trying to link, authenticate and download static content and files. Using the Azure Content Delivery Network (CDN), Power BI effectively distributes the required static content and files to customers based on geographic location.2. Backend Cluster:How authenticated customers interact with the Power BI service is the Back-End cluster. The Back-End cluster manages visualization, user dashboards, datasets, reports, data storage, information links, information refresh, and other elements of Power BI service interaction. The Role Gateway functions as a gateway between customer demands and the service Power BI. Users are not directly interacting with positions other than the role of the Gateway. The Gateway Role will ultimately be managed by Azure API Management.How Power BI can be a game-changer for the enterprise?Power BI combines centralized DW / BI strategies with cloud data sources and self-service tools through its data catalog and data management gateway, as no other platform has yet been able to do. And as a SaaS solution, all its functionality is packaged so that it can be easily implemented and used by any organization. In brief, Power BI can speed up the adoption curve and make sophisticated BI Analytics as prevalent as Excel itself.Power BI provides all BI system stakeholders with game-changing capabilities: 1. End-users:End-users wanted the capacity to access and evaluate information readily for a long time. The natural language query of Q&A and the smart visualization engine will do more to encourage each worker to use data as a basis for decision making.2. BI Analysts:Power Pivot provided power users with the capacity to create effective data models over big amounts of data, but the information required to "fit" into clean data models. The data transformation and flexibility of Power Query further empowers analysts to rapidly create their own end-to-end alternatives.3. IT & Data Managers:BI self-service has always been a subject of push-pull. Everyone wants the instruments and data that consumers need to create excellent choices.
