Business Transformation through Enterprise Cloud Computing

The Cloud Best Practices Network is an industry solutions groups and best practices catalogue of how-to information for Cloud Computing. While we cover all aspects of the technology our primary goal is to explain the enabling relationship between this new IT trend and business transformation, where our materials include: Core Competencies – The mix of new skills and technologies required to successfully implement new Cloud-based IT applications. Reference Documents – The core articles that define what Cloud Computing is and what the best practices are for implementation, predominately referring to the NIST schedule of information. Case studies – Best practices derived from analysis of pioneer adopters, such as the State of Michigan and their ‘MiCloud‘ framework . Read this article ‘Make MiCloud Your Cloud‘ as an introduction to the Cloud & business transformation capability. e-Guides – These package up collections of best practice resources directed towards a particular topic or industry. For example our GovCloud.info site specializes in Cloud Computing for the public sector. White papers – Educational documents from vendors and other experts, such as the IT Value mapping paper from VMware. Core competencies The mix of new skills and technologies required to successfully implement new Cloud-based IT applications, and also the new capabilities that these platforms make possible: Virtualization Cloud Identity and Security – Cloud Privacy Cloud 2.0 Cloud Configuration Management Cloud Migration Management DevOps Cloud BCP ITaaS Procurement Cloud Identity and Security Cloud Identity and Security best practices (CloudIDSec) provides a comprehensive framework for ensuring the safe and compliant use of Cloud systems. This is achieved through combining a focus on the core references for Cloud Security, the Cloud Security Alliance, with those of Cloud Identity best practices: IDaaS – Identity Management 2.0 Federated Identity Ecosystems Cloud Privacy A common critcal focus area for Cloud computing is data privacy, particularly with regards to the international aspects of Cloud hosting. Cloud Privacy refers to the combination of technologies and legal frameworks to ensure privacy of personal information held in Cloud systems, and a ‘Cloud Privacy-by-Design’ process can then be used to identify the local legislated privacy requirements of information. Tools for designing these types of privacy controls have been developed by global privacy experts, such as Ann Cavoukian, the current Privacy Commissioner for Ontario, who provides tools to design and build these federated privacy systems. The Privacy by Design Cloud Computing Architecture (26-page PDF) document provides a base reference for how to combine traditional PIAs (Privacy Impact Assessments) with Cloud Computing. As this Privacy Framework presentation then explains these regulatory mechanisms that Kantara enables can then provide the foundations for securing the information in a manner that encompasses all the legacy, privacy and technical requirements needed to ensure it is suitable for e-Government scenarios. This then enables it to achieve compliance with the Cloud Privacy recommendations put forward by global privacy experts, such as Ann Cavoukian, the current Privacy Commissioner for Ontario, who stipulates a range of ‘Cloud Privacy By Design‘ best practices Cloud 2.0 Cloud is as much a business model as it is a technology, and this model is best described through the term ‘Cloud 2.0′. As the saying goes a picture tells a thousand words, and as described by this one Cloud 2.0 represents the intersection between social media, Cloud computing and Crowdsourcing. The Social Cloud In short it marries the emergent new online world of Twitter, Linkedin et al, and the technologies that are powering them, with the traditional, back-end world of mainframe systems, mini-computers and all other shapes and sizes of legacy data-centre. “Socializing” these applications means moving them ‘into the Cloud’, in the sense of connecting them into this social data world, as much as it does means virtualizing the application to run on new hardware. This a simple but really powerful mix, that can act as a catalyst for an exciting new level of business process capability. It can provide a platform for modernizing business processes in a significant and highly innovative manner, a breath of fresh air that many government agency programs are crying out for. Government agencies operate many older technology platforms for many of their services, making it difficult to amend them for new ways of working and in particular connecting them to the web for self-service options. Crowdsourcing Social media encourages better collaboration between users and information, and tools for open data and back-end legacy integrations can pull the transactional systems informtion needed to make this functional and valuable. Crowdsourcing is: a distributed problem-solving and production process that involves outsourcing tasks to a network of people, also known as the crowd. Although not a component of the technologies of Cloud Computing, Crowdsourcing is a fundamental concept inherent to the success of the Cloud 2.0 model. The commercial success of migration to Cloud Computing will be amplified when there is a strong focus on the new Web 2.0 type business models that the technology is ideal for enabling. Case study – Peer to Patent One such example is the Whitehouse project the Peer to the Patent portal, a headline example of Open Government, led by one its keynote experts Beth Noveck. This project illustrates the huge potential for business transformation that Cloud 2.0 offers. It’s not just about migrating data-center apps into a Cloud provider, connecting an existing IT system to a web interface or just publishing Open Data reporting data online, but rather utilizing the nature of the web to entirely re-invent the core process itself. It’s about moving the process into the Cloud. In this 40 page Harvard white paper Beth describes how the US Patent Office was building up a huge backlog of over one million patent applications due to a ‘closed’ approach where only staff from the USPTO could review, contribute and decide upon applications. To address this bottleneck she migrated the process to an online, Open version where contributors from across multiple organizations could help move an application through the process via open participation web site features. Peer to Patent is a headline example of the power of Open Government, because it demonstrates its about far more than simply publishing reporting information online in an open manner, so that they public can inspect data like procurement spending numbers. Rather it’s about changing the core decision-making processes entirely, reinventing how Government itself works from the inside out, reinventing it from a centralized hierarchical monolith to an agile, distributed peer to peer network. In essence it transforms the process from ‘closed’ to ‘open’, in terms of who and how others can participate, utilizing the best practice of ‘Open Innovation‘ to break the gridlock that had occured due the constraints caused by private, traditional ways of working. Open Grantmaking – Sharing Cloud Best Practices Beth has subsequently advised further on how these principles can be applied in general across Government. For example in this article on her own blog she describes ‘Open Grantmaking‘ – How the Peer To Patent crowdsourcing model might be applied to the workflows for government grant applications. She touches on what is the important factor about these new models, their ability to accelerate continual improvement within organizations through repeatedly sharing and refining best practices: “In practice, this means that if a community college wins a grant to create a videogame to teach how to install solar panels, everyone will have the benefit of that knowledge. They will be able to play the game for free. In addition, anyone can translate it into Spanish or Russian or use it as the basis to create a new game to teach how to do a home energy retrofit.” Beth describes how Open Grantmaking might be utilized to improve community investing in another blog, describing how OG would enable more transparency and related improvements. Cloud 2.0 As the underlying technology Cloud 2.0 caters for both the hosting of the software and also the social media 2.0 features that enable the cross-enterprise collaboration that Beth describes. Cloud Configuration Management CCM is the best practice for change and configuration management within Cloud environments, illustrated through vendors such as Evolven. Problem Statement One of the key goals and perceived benefits of Cloud computing is a simplified IT environment, a reduction of complexity through virtualizing applications into a single overall environment. However complexity actually increases.  Virtual Machines (VMs) encapsulate application and infrastructure configurations, they package up a combination of applications and their settings, obscuring this data from traditional configuration management tools. Furthermore the ease of self-service creation of VMs results in their widespread proliferation, and so actually the adoption of Cloud technologies creates a need for a new, extra dimension of systems management. This is called CCM, and incorporates: Release & Incident Management The increased complexity therefore increases the difficulties in trouble-shooting technical problems, and thus requires an updated set of tools and also updates to best practices like the use of ITIL procedures. ‘Release into Production’ is a particularly sensitive process within software teams, as major upgrades and patches are transitioned from test to live environments. Any number of configuration-related errors could cause the move to fail, and so CCM software delivers the core competency of being better able to respond quicker to identify and resolve these issues, reducing the MTTR significantly. DevOps DevOps is a set of principles, methods and practices for communication, collaboration and integration between software development and IT operations. Through the implementation of a shared Lean adoption program and QMS (Quality Management System) the two groups can better work together to minimize downtimes while improving the speed and quality of software development. It’s therefore directly linked to Business Agility. The higher the value of speed and quality = a faster ability to react to market changes, deploy new products and processes and in general adapt the organization, achieved through increasing the frequency of ‘Release Events’: It’s therefore directly linked to Business Agility.

Moving to Cloud services means changing from a financial model for technology where you buy your own hardware and software, and pay for it up front, to an approach where instead you access it as a rental, utility service where you “PAYG – Pay As You Go”. To encompass all the different ‘as a Service’ models this is known at an overall level as ‘ITaaS’ – IT as a Service. Any type of IT can be virtualized and delivered via this Service model.

Core competencies

The mix of new skills and technologies required to successfully implement new Cloud-based IT applications, and also the new capabilities that these platforms make possible:

  • Virtualization
  • Cloud Identity and Security –
  • Cloud Privacy
  • Cloud 2.0
  • Cloud Configuration Management
  • Cloud Migration Management
  • DevOps
  • Cloud BCP

Organizations are hiring Solutions Architects to help them design and develop advanced cloud-based solutions as well as migrate their infrastructure and workload to the existing AWS cloud. There are limitless virtual resources on the AWS platform that can be provisioned and disposed of. With these many resources available at their disposal, a Solutions Architect must have the skills to handle the data and infrastructure. Here are a few skills a solutions architect must have:1. Programming languageIt is the most basic and important skills for a Solutions Architect. Since they have a background in software development, this won’t be new to them. As a solutions architect, you must be skilled in Python, Java, C# or any programming language with an official AWS SDK. Having programming skills will help you to create logical and viable solutions. Also, it can be used for creating a demo or proof of concept for showing a point or learning how to use the latest technology.2. NetworkingKnowledge of networks like DNS, VP, HTTP, TCP/IP, and CDN will help you in creating a scalable and secure cloud-based solutions. You must also have working experience in services like CloudFront (CDN), Route 53 (DNS), and Virtual Private Cloud (VPC). This will help you in using the public as well as private subnets, VPC peering, and internet access for designing your cloud network.3. Data StorageAs a Solutions Architect, you must have knowledge of databases. There are several data storage options available on the AWS platform. This includes powerful and simple bucket storage like S3, relational database service, and Hadoop clusters. To select the one for your company’s data, you will have to compare different databases’ performance, capabilities, and price.4. SecurityThere are services and guidelines laid down by the AWS like securing access to your data and AWS account to ensure that only authorized people and code are allowed for performing specific tasks. You must also have a thorough understanding of the Identity and Access Management (IAM) that is used for defining which user and services can access the resources. You need to learn about securing your network through Access Control Lists and Security Groups.5. AWS Service SelectionWhen it comes to cloud architecture, AWS provides several front-end as well as back-end technologies. As a solutions architect, you must have the skills required for knowing which services are relevant to your organization. You must know what your end goal is. For this, you must have knowledge of SNS (notifications), SQS (Simple Queuing), RDS (Relational Database Service), and IoT related services.6. Cloud-specific technologiesThere are different rules while using cloud. As long as you correctly design and harness AWS infrastructure, availability, scalability, and recovery are comparatively easy. To create cost-effective and scalable applications, you need to use storing state and messages, and handle failures correctly. If you want to create applications which can be scaled through creating instances of the same service, you need to use patterns like eventual consistency, queuing, and pub/sub.7. CommunicationYou need to be able to explain your vision to managers, software developers, and fellow architects through documents, emails and presentations. You need to learn how to write in a concise, clear way, presenting your idea and displaying complex environments through diagramming tools. Apart from the above-mentioned skills, you must have the following relevant working experience:Software developmentData securityNetworkingAWSAlso, you must have hands-on experience working with Linux, the architect’s toolbox (Chef, Puppet, Docker, Capistrano, Jenkins, and Ansible), Infrastructure as code (CloudFormation), advanced project management tools, etc.Why Architecting in AWS?With Architecting in AWS, you will be able to perform the following:Application of the frameworkManaging multiple accounts for the organizationConnecting the AWS cloud to the on-premises dataDiscussing the billing to connect VPCs of multi-regionTransferring large data to AWS from the on-premises data centerDesigning large data centersUnderstanding architectural designs used to scale a large websiteProtecting the infrastructureUsing encryption to secure the dataEnhancing the solutions’ performanceOnce you get the AWS Solutions Architect certification, you will have a high-opportunity market and greater earning potential. This certification is one of the best paying certifications in the IT sector. It is perfect for people working on improving their AWS cloud skills pursuing a worthy certification path. Also, Solutions Architect working on the AWS with the certification can get an average annual salary of $114,000.AWS Certified Solutions Architect Exam ScheduleTo prepare for the AWS Certified Solutions Architect exam, you will need at least three months during which, you will cover the AWS ecosystem and general concepts of cloud computing. The first step is to create a document where you will mention everything that you will learn. This will be your study guide.The first monthThe task for the first month is to lay the groundwork. In this, you will get an introduction to the Ecosystem of AWS and how core AWS services interact with each other. It is the hardest month. So, you need to stay focused and vigilant.The second monthThis month you build the foundation. You need to keep up with your pace.

What is Cloud Computing Architecture?

What is Cloud Computing Architecture?One of the biggest tech trends to emerge in recent years is cloud computing. Of course, there is a good reason behind that. There are many benefits to moving your business to the cloud. To name a few, it offers easy accessibility, flexibility, storage, and sharing. Companies of all sizes can utilize cloud to their advantage. In fact, cloud is even being used for day to day activities. Services like Spotify and Google Docs are provided via virtual networks.Why Cloud Computing?Over the years, there has been a significant increase in users of computers and mobile devices. With such increase, data storage requirements have also gone up. Businesses of all sizes make use of data for understanding day-to-day operations, making business decisions and learning about their customers. They even spend a huge amount of money for the maintenance of this data. This requires a storage hub as well as sufficient IT support.However, it is not possible for all businesses to be able to afford the expenses of having an IT infrastructure in-house and availing support services. Here, cloud computing serves as a more inexpensive solution. In fact, even the big businesses are attracted to cloud, probably because of less maintenance cost and data storage efficiency it provides.Implementation of cloud computing means there would be a decreased software and hardware demand from the user end. For the users, the cloud computing systems interface software is the only thing that needs to run. Even something like a Web browser can serve as this software. For the rest of it, the Cloud network does its job. Whether you realize or not, you have used cloud computing in one form or the other. Some of the most commonly used cloud services are mail services such as Gmail, Yahoo, Hotmail, etc.When you use email services, your data is not stored on your computer. Instead, your data is on a cloud server. The infrastructure and technology behind the cloud are not visible. As far as cloud services remain functional and user-friendly, what mostly matters whether it is based on PHP, HTTP, Ruby, XML, or other technologies. Individual users can connect to the cloud system directly from their own devices, be it a mobile, a desktop or a laptop.Small businesses have limited resources and they can harness cloud computing effectively to their advantage. With the cloud, small businesses get access to the kind of technologies which weren’t accessible to them before. These companies can actually make profits out of the maintenance cost by using cloud computing.If you have an in-house IT server, there would be a need to pay specific attention to make sure that the system operates smoothly without any flaws. In case a technical error does occur, it will be completely your responsibility. Resolving such errors is likely to cost you a lot of money and time as well. On the other hand, with cloud computing, the entire responsibility of any technical fault or complication is on the service provider. This allows you to operate without any distraction.Benefits Offered by Cloud ComputingThe main reason why so many organizations have incorporated cloud services is the potential it offers in terms of cost savings. Cloud computing offers the flexibility of using services only according to the requirement of the user. The user pays only for what they use. It is mainly cloud computing that has provided the freedom of outsourcing IT operations without the need for in-house resources. Some major benefits of cloud computing include:Lower IT infrastructureLower computer costs for usersFewer issues with maintenanceBetter performanceBetter compatibility between Operating systemsInstant software updatesEasier backup and recoveryImproved storage capacityScalability and PerformanceImproved data safetyWhat is Cloud computing architecture:Cloud architecture basically refers to the different components engineered for solving business problems by leveraging the power of cloud resources. These components can be related to software capabilities, databases, applications, etc. It is the cloud architecture that defines the components and relationships between them. The different components of cloud architecture include:Cloud resourcesOn-premise resourcesMiddlewareSoftware services and componentsThe main objective of the complete cloud architecture is to provide high bandwidth to the users, which will provide them with uninterrupted access to applications and data. Users get an agile on-demand network that offers the possibility of moving efficiently and quickly between servers and even clouds. More important than anything else, users get network security.The file system is distributed by cloud computing and it spreads over multiple systems and hard drives. The storage of data is never done at a single place. Different units serve as a backup when one of the units fails. This distributed file system has allocations of user disk space. As far as resource allocation is concerned, another crucial component is the algorithm to allocate resources. Since cloud computing is a strongly distributed environment, it depends heavily on a strong algorithm.Primary Components of Cloud ArchitectureWhen it comes to cloud computing architecture, the main concern is the different components as well as the sub-components of clouds that form the part of the system structure. The cloud computing architecture mainly includes:A front-end platform that includes all types of clients and mobile devicesBack-end platforms such as storage and serversCloud-based deliveryA network, usually the internet or intranetIn its most basic form, there are primarily two sections of classification of cloud architecture: the front end and the back end. The internet or a virtual network connects the front end with the back end. Cloud architecture also has other parts such as cloud resources, middleware, etc.In a sense, cloud computing can be considered to be the building block of the Internet of Things (IoT), which allows anything to be connected to the internet. The architecture of cloud system combines both event-driven architecture and service-oriented architecture. The complete cloud architecture encompasses all the elements that form the cloud environment.Businesses make use of cloud infrastructure for working with applications. The payment structure provided by the cloud is a lot different from the conventional pricing model that is based on subscription. This payment model allows users to subscribe to vendor services and a “pay per use” basis is used for paying cloud infrastructures.Front end cloud computingIt is the front-end side of cloud computing that is visible to users, customers or clients. The main part of the front end is the user interface as well as the network and computer system of the client that is used to access the cloud system. You will likely have noticed that the user interface is usually different from different systems of cloud computing. As a most basic example, various web browsers such as Chrome, Firefox, Safari, etc. all have a unique user interface of their own. Not just that, the user interface of Salesforce is noticeably different from that of Google Docs.The front-end platform of cloud computing technology is also called cloud client and it consists of servers, fat and thin clients, mobile devices and tablets. The interaction takes place through a web browser or a middleware or even virtual sessions.Back end cloud computingAs far as the back-end side of cloud computing is concerned, it is the side that the service provider uses. This includes the different servers, data storage systems, computers, programs and virtual machines that together form the cloud of computing services. It is the back-end cloud computing that is responsible to provide security mechanisms, the protocol for communication for connecting networked computers, and traffic control. The back-end provides data security to users.The server also employs specific protocols called middleware that allow connection between devices, facilitating communication between them.Different Types of CloudsA user can subscribe to any of four different cloud models as per the needs of the business:Private Cloud: In this case, the deployment of computing resources is done only for one specific organization. It is the method that is primarily used for interaction within the business.Community Cloud: The computing resources, in this case, is deployed for community and organizationsPublic Cloud: It is a type of cloud that is typically used for interaction that takes place from business to customer. In this case, a business or academic organization or the government owns, operates and governs the computing resource.Hybrid Cloud: It is a type of business that can be used for a different type of interactions, be it from business to customer or among different businesses. This method of deployment binds computing resources together with the use of different clouds, hence it is called hybrid cloud.Types of Cloud Computing ServicesThe different cloud-based services have their own unique and distinct architectures. The major offerings include:Software as a Service (SaaS): This involves software being hosted and maintained on the internet, with there being no requirement for software installation on behalf of the user. SaaS is the preferred underlying delivery model for supporting Web Services or SOA (Service Oriented Architecture). Users from any part of the world can access this service via the internet.Development as a Service (DaaS): It involves web-based development tools being shared across different communities.Platform as a Service: In this case, users are provided databases and platforms, similar to middleware services. PaaS includes management services and software support, storage, deploying, collaborating, networking, testing, maintenance and hosting applications.Infrastructure as a Service (IaaS): With IaaS, hardware and infrastructure like servers, storage devices, networks, etc are provided and these run in the cloud. The users can avail the infrastructure on a pay per usage basis. The hardware resource pool is formed of multiple networks and servers that are distributed over different data centers, thus providing reliability and redundancy.Cloud computing and security concernsThe main cause of concern for users when it comes to cloud computing is its security. The most common concern is that the cloud services providers may themselves get access to the unencrypted data of the customers, be it in memory, on disk or even over network transmission.The government of some countries may even decide on searching through data and wouldn’t probably even notify the user who owns the data. This is certainly not acceptable and is a breach of the privacy of the concerned user.For providing security for data, networks, and systems, cloud providers are working with a non-profit organization TCG (Trusted Computing Group). TCG provides certain specifications for securing hardware, improving network security and creating self-encrypting drives. These specifications protect data from malware and rootkits. With different devices being used for computing, the security measures provided by TCG also include these devices, thus providing a unified policy for data protection. When it comes to security, Gmail and Amazon are examples of cloud services that you can trust.Hope this article was able to answer all your queries on the Amazon Web Services. Now that you are familiar with the fundamentals of AWS that will help in expanding the infrastructure of your organization, you can get started with KnowledgeHut’s AWS certification course.

Amazon Elastic Load Balancer: Definition, Benefits and Features

Elastic Load Balancing handles the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones. It automatically distributes incoming application traffic across multiple targets, such as Lambda functions, IP addresses, containers, and Amazon EC2 instances.Types of Elastic Load BalancerELB consists of three diverse types of load balancer which help to achieve extensive cloud computing measures. These include:Classic Load Balancer (CLB): This is the most fundamental way of load balancing which replaces the conventional physical hardware with virtual devices to provide an optimum level of experience. Classic Load Balancer is usually designed for the applications that are within EC2 classic networks. It functions both at the request and connection level.Application Load Balancer (ALB): It functions to route advanced traffic to targets such as EC2 instances, IP addresses, containers, Lambda functions depending on the request. Application Load Balancer provides advanced request routing such that incoming traffic can be routed against multiple availability zones. Application Load Balancer contributes towards safeguarding the security of the applications by using designated protocols and ciphers. It can route the request on the basis of the content.Network Load Balancer (NLB): Network Load Balancer operates at the connection level i.e Layer 4 when a target becomes slow or unavailable it routes the traffic to another target within Amazon Virtual Private Network based on IP Protocol suited for both TCP and UDP traffic. Network Load Balancer is capable of handling millions of requests per second while it grows and can handle sudden volatile traffic patterns using a single static IP address. It can maintain ultra-low latencies. It is an amalgamation of various recognized AWS services such as Auto Scaling, Amazon EC2 Container Service (ECS), Amazon CloudFormation and AWS Certificate Manager (ACM).Benefits of Load Balancing in AWS environment:1. Highly available: Electric load balancing can route traffic to multiple targets automatically and can also load balance across a region routing towards a proper target in multiple availability zones.2. Secure: The TLS settings can be centrally managed and one can even discharge the workloads of the CPU while working with Amazon Virtual Private Network Cloud providing sustainable security, user authentication, integrated certificate management, and SLS/TLS decryption.3. Flexible: The applications could interact among each other through a microservice-based architecture and one can customize the application targets by the use of IP address in Elastic load balancer. 4. Elastic: It can manage rapid fluctuations in traffic and with the incorporation of auto-scaling, it can meet the various levels of measurable capacity with least manual involvement.5. Hybrid load balancing: It is convenient to drift, switchover or migrate on-premises applications to the cloud since the elastic load balancer can balance load across AWS and on-premises using the same load balancer.6. Robust monitoring and auditing: One can keep a track of activities of the applications, resolve the issues and know the cause of the problem by surveying the performance in real time with the assistance of Amazon CloudWatch metrics, logging and request tracing in Elastic load balancer.Features of Elastic Load BalancingSecurity: It uses Amazon Private Virtual Network Cloud thus providing extra security to the load balancers and one can even create an internal load balancer.Health checks: It can track unfit targets and prohibits the flow of load towards and then balances the load towards the working targets.TLS termination: With the help of SSL/TLS decryption and integrated certificate management, the CPU is offloaded and the SSL settings are managed at the core. High availability: It can automatically distribute traffic to multiple availability zones or single availability zone working on the same load balancer.Operational Monitoring: With Amazon CloudWatch metrics, logging and request tracking, one can overview the working in real-time.Layer 4 and Layer 7 balancing: HTTP/HTTPS  applications can be used to load balance for 7 Layer or strictly for layer 4 which depends on UDP and TCP controls.Product Comparisons: Being flexible in nature, one can make choices on the basis of the need of the applications; such as one using an EC2-classic network can use a classic load balancer or if a flexible application is needed, one can use the Application load balancer.AWS is the present and the future. We hoped this article helped you get familiar with the services offered by the AWS. If you want to know more about AWS and get certified, you can try the  AWS certification course offered by KnowledgeHut.
