Best Practices For Successful Implementation Of DevOps

What is DevOps?DevOps is nothing but the combination of process and philosophies which contains four basic component culture, collaboration, tools, and practices. In return, this gives a good automated system and infrastructure which helps an organisation to deliver a quality and reliable build. The beauty of this culture is it enables a quality for organizations to better serve their customers and compete more effectively in the market and also add some promised benefits which include confidence and trust, faster software releases, ability to solve critical issues quickly, and better manage unplanned work.                                       “DevOps is not a goal, but a never-ending process of continual improvement.”                                                                           Jez Humble Here are the key DevOps best practices that can help you for successful implementation of DevOps.1. Understand Your Infrastructure need: Before building the infrastructure, spend some good time to understand the application and then align your goals to design your Infrastructure and this implementation of DevOps should be business-driven. While understanding infra, make sure you are capturing below components:Cycle Time : Your software cycle needs to be defined in a generic way where you need to know the limitations, ability and if there is any down time then the exact time need to be noted.Versioning Environments: While planning DevOps, always be ready for an alternative solution and versioning your environments helps you to roll out/back your plan. If you are having multiple module and tightly coupled then it requires a clean and neat plan to identify each and every patch and release.Infra as a code: When we say infra as a code it means a solution to addressing both needs – minimizing cycle time and versioning environments can be addressed by capturing and managing your Infrastructure as code. What you built should scalable for a long run.2. Don’t jump start : There is no need to automate the complete cycle in one shot, always take a small entity and apply your philosophy and get this validated. Once you feel your POC is justified, start scaling up now and create a complete pipeline and define a process so anytime you can go back and check what all need to improve and where. All these small success will help you to get confidence internally in your team and builds a trust to stakeholder and your customers.                                                        “DevOps isn’t magic, and transformations never happen overnight”3. Continuous Integration and Continuous Deployment: If  your team is not planning to implement this continuous integration and continuous delivery, then it is not fair with DevOps. Even I’ll say the beauty of DevOps is how frequently your team can deliver without disturbance and how much you are automated in this process. Let’s take a use case: You and your team members are working in an Agile team. In fact, there are multiple teams and multiple modules which are tightly coupled  in which you are also involved. Every day you work on your stories and at the end of the day, you push your ‘private build’ of your work to verify if it builds and ‘deliver’ it to a team build server and same applies to other individuals. Which indicates you all ‘integrate’ your work in the common build area and do an ‘Integration Build’. Doing these integrations and builds to verify them on a regular, preferably daily basis, is what is known as Continuous Integration.Continuous Deployment doesn’t mean every change is deployed to production as soon as possible. It means every change is proven to be deployable at any time.  What it takes is your all validated feature and build from CI and deploys them into the production environment. And here we can follow some of the practices. a) Maintain a Staging Environment that Emulates Production b) Always deploy in staging then move to production c) Automate Testing of Features and Nonfunctional Requirements d) Automatically fetch version-controlled development artifacts.4. Define Performance and do benchmarking : Always do some performance testing and get a collective benchmarking report for the latest build shared by your team because this will only justify the quality of your build and the required infra as well.For example : We have done one performance testing a few days back and got good results, explaining in details. So we did some benchmarking for our CFM machines because we are having a global footprint and at the same time, for us, latency matters and we need CFM in the nearest region. We have verified with our current build how many requests we can handle and we found we are firing more than 200 RPS (request per second). So we planned to check our build capability and fired a good number of requests and noted the number where our build got crashed and noted the RPS and then we did autoscaling of CFM. We might have upgraded our CFM but we planned for auto scaling because the number of requests is an assumption and we don’t want to spend amount for that but at the same time we are ready to consume the experimented traffic. And then we found 7 out 2 CFM are only consuming exact or little less number configuration and request (181 to 191 RPS). So we shared a report to the business team to focus on other regions where we were having very less traffic because we were paying the same amount.Conclusion: We verified our build which has given good confidence to our dev team and we shared the report to the business team which helped them to plan their marketing strategies, meanwhile we completed auto scaling the process as well.  5. Communicate and Collaborate : Collaboration and communication are the X-factors to help organisation grow and assess for DevOps. Collaboration with business and development team helps DevOps team to understand to design & define a culture. This helps to speed up the development, operations, and even other teams like marketing or sales, allowing all parts of the organization to align more closely with goals and projects.6. Start Documenting : Document everything (All your work done) which you are spreading across the process and infrastructure and specially the reports, RCA’s (Root cause Analysis), change management. This helps you to go back and see if all issues we faced can be automated in the next cycle or other ways to handle them smoothly without interrupting your production environment.7. Keep your eyes on cost burning: It has been experienced many a time that if we don’t keep an eye on cloud bills it will keep increasing and will tend to be proportional to the growth of your business till the time you don’t look for optimization. Always do an audit in 2 months and evaluate your cloud computation to optimize. Do some experiment with infra because you should not spend not more than 5  to 10 % of cost for cloud infra if you are completely dependent. Tools you can try : Reoptimize, Cloudyn, Orbitera etc.                                                                                 “If you are DevOps you should account the no’s.”8. Secure your infra : If your team follows certain compliances from day 1 then there is very less chance to compromise with your data and this can be easily enabled by providing a setup where you can verify your vulnerabilities. Before moving your build to the production team you may need to follow the standard at an early stage of development by using configured tools like: SonarQube, VeraCode, Codacy, CodeClimate etc.9. Tool Selection : Always select tools which all are compatible with rest of the toolchain you are planning to use. Why you should have to be so careful is because you have to capture each and every request capture. Once you are done with the tool selection, draft a tools metrics you are willing to capture or will be going to help you to debug. Start logging and monitoring them and have some clear definition for those logs so you can justify and determine that your processes are working as expected. Tools you can have a look : Nagios, Grafana, Pingdom, Monit, OpsGenie, Observium, Logstash etc.                                                                                                        Tool chain for DevOps process:                                                                             “If you are not monitoring,  you are not in the production”Conclusion:An organization that follows all the above best practices creates the right culture, which finally gets the ending it deserves i.e DevOps organization. "A good DevOps organization will free up developers to focus on doing what they do best: write software," says Rob Steward, Vice President of product development at Progress Software. "DevOps should take away the work and worry involved in deploying, securing and running the software once it is written."

Top Devops Tools You Must Know

In the last decade for most of the enterprises, the term DevOps has transformed from just a buzzword to a way of working. The concept of DevOps originated in 2008 following a discussion on agile infrastructure by Patrick Debois and Andrew Clay Shafer. The idea started to gain momentum in 2009 after the first DevOpsDays in Belgium. What initially began as a practice to bring more efficiency in software infrastructure management, is now evolved into a continuous feedback model which has redefined every aspect of software development from requirement engineering to deployment. With this change, evolved new frameworks, practices and tools rooted in the core values of lean and agile. This paper discusses in detail the various tools that evolved during the DevOps movement. Readers would get a comprehensive understanding of what and where to apply these tools in their day to day DevOps journey.1. What is DevOps?DevOps is a culture where active collaboration between development, operations, and business teams are achieved. It’s not all about tools and DevOps in an organisation is to create value to end customer respecting human all team members. Tools are only aids to build this culture. DevOps increases organizations capability to deliver high-quality products or services at a swift pace. It automates all processes starting from build to deployment phase of an application. There are many tools available in the market to help us achieve this.2. What are the DevOps tools?DevOps tools are categorized into following categories:a. Collaboration Tools :DevOps teams rely on regular feedback and constant communication. Hence traditional email communication mechanism becomes less effective. Thus DevOps teams rely on more integrated collaboration suites that help in continuous communication and feedback loops. Some of these new generation collaboration tools include Slack, Teams, CA Flowdock etc.1. SlackSlack is a messaging tool for the teams providing a common place for all communications. We can set different channels for different kinds of work. Voice and video call options are also available with Slack. Atlassian and Slack have created a partnership and will be discontinuing other collaboration tools like Hipchat and Stride and will provide migration to Slack.Availability: Free version with limited features are available for users.For more details click here  2. CA FlowdockCA Flowdock is yet another collaboration tool from CA Technologies. It brings all conversations, chats, work items, etc to one place making it easier to prioritize work and solve problems.Availability: CA Flowdock is free for up to 5 member teams and free for non-profit organizations and student projects.Learn more about CA Flowdock here.     3. TeamsTeams is a unified communication platform by Microsoft. Teams combine workplace chats, video meetings, file storage, and application integration. The service also integrates with the company's existing Office 365 productivity suite and features extensions to integrate with non-Microsoft products and features.Availability: Teams is free for a small number of users.Learn more about Teams here.SL NoTool NameProsConsAvailability1.SlackIntuitiveSaaS productGood integration with other toolsThe video conferencing feature is not as great as its competitorsFreemium2.CA FlowdockEasy to configureIntegration with tools beyond CA tools is to be improvedFreemium for small users3.TeamOne stop shop -  Integrates file sharing, messaging, meetings, and other tools.Still early and could be a little buggyFreemium for small usersb.

Why is DevOps needed?DevOps helps to remove silos in organisations and enable the creation of cross-functional teams, thus reducing reliance on any one person or team during the delivery process. Frequent communication between teams improves the confidence and efficiency of the team members. Through automation, DevOps team increase their productivity making satisfied customers. According to State of DevOps report 2016 “Teams that practice DevOps deploy 30x more frequently, have 60x fewer failures, and recover 160x faster“. It also provides better work environments with increased trust, better management of issues reducing unplanned works.4. How to implement DevOps?The “DevOps Handbook” defines the “Three Ways: The principles of underpinning DevOps” as a way to implement DevOps in large enterprises. In this session, we will detail these three ways and three core pillars.The First Way: Systems ThinkingThe First Way emphasizes the need for global optimisation as opposed to local optimisation, hence the focus is on optimising all business value streams enabled by IT.The Second Way: Amplify feedback loopsThe Second Way is about discovering and injecting right feedback loops so that necessary corrections can be made before it’s too late.The Third Way: Culture of Experimentation and learningThe third way is all about creating the right culture that fosters two things, continual experimentation and learning from failures. It emphasises the understanding that repetition and practice make teams perfect.While the three ways focus on the key principles, we also have three pillars which are keys to any successful DevOps adoption.The three pillars of any DevOps adoption are,Culture and PeopleTools and TechnologyProcesses and practices4.1 Important DevOps practicesa. Continuous IntegrationContinuous integration is a software engineering practice where software development team members frequently merge and build their code changes. The key benefit is to detect and fix code merge conflicts and integration bugs in the early stages of software development. Hence reducing the cost to detect and fix the issues.b. Continuous DeliveryContinuous delivery is a software engineering practice in which changes are automatically built, tested, and made release ready to production. In order to get into a continuous delivery state, it is very crucial to define a test strategy. The main goal is to identify functional and non-functional defects at a much earlier stage thus reducing the cost to fix defects. It also enables teams to come up with working software as defined in the agile manifesto. Continuous delivery as a practice depends on continuous integration and test automation. Hence it is crucial that teams need to ensure that they practice continuous integration along with test automation religiously, to effectively practice continuous delivery.c. Continuous DeploymentContinuous deployment is a software engineering practice in which codes committed by the developers are automatically built, tested and deployed to production. Continuous deployment as a practice, require that teams have already adopted continuous integration and continuous delivery approach. The primary advantage of this practice is reducing time-to-market and early feedback from users.d. Continuous TestingContinuous Testing can be defined as a software testing practice that involves a process of testing early, testing often and test automation. The primary goal of Continuous Testing is to shift left the test phase as much as possible to identify defects and reduce the cost of fixing.e. MicroservicesMicroservices architecture helps to create an application as a set of small services independent of each other. Any language could be used to create microservices and typically an HTTP based API is used to interact between services. Microservices as a design approach helps to achieve fewer risk deployments and enables continuous delivery.f. Infrastructure as codeInfrastructure as a code is an engineering practice in which infrastructure is developed and managed through code. Thus creating a consistent, reproducible and versioned infrastructure. Since the infrastructure is implemented as the code it’s easy for the team members to update and change it. Infrastructure as a code no more considers scaling as a major problem.g. Policy as codePolicy as a code is a software engineering practice where compliance rules or policies of the organisation could be monitored and verified. Policy as code enables organizations to enforce the compliance rules more strictly and helps to bring the non-compliant resource into compliance mode. This practice gained importance during the DevSecOps movement.h. Continuous Monitoring and LoggingMonitoring and logging as a best practice to help organizations to analyse the products’ end user experience. This helps the software teams to get to know about the root cause of the defects and latencies in the software development process. More transparency into the actions performed by the team members causes increased responsibility among the teams causing increased performance.i. Communication and collaborationEffective communication and collaboration are one of the key values emphasised by DevOps.Devops tools in the field of communication and collaborations bring together collective responsibility for the products delivered.   5. How to choose the right DevOps tools?Today the DevOps market is overcrowded with tools across different stages of software development life cycle. As enterprises, it's extremely crucial to select the right tools in order to get maximum benefit. Saying so choosing the right tool is an extremely difficult and time-consuming process given the spectrum of tools available today. Hence enterprises should have a five-point strategy towards deciding the right tools. Five point strategy would include dimensions likeAbility to integrateScalabilitySecurityTechnical know howReliability5.1. Ability to integrateThe ability to integrate is extremely crucial and is one of the fundamental requirements while checking out tools. Certain tools integrate smoothly with a particular technology stack in comparison with others. Hence it is vital for the DevOps architect to compare different tools on the basis of integration ability and ensure that tool that is been selected seamlessly integrates with the team’s technology stack. Another aspect that needs to be considered is how a particular tool integrates with other tools that are selected in the ecosystem. For eg., you would want your continuous integration system to constantly talk to the reporting system and alert prediction system in a smooth way. Hence integration between tools also becomes a very important factor while choosing tools.5.2. ScalabilityScalability is the second most important factor in choosing the right tools. Based on the need for scalability an enterprise might choose an enterprise version over a community version. Scalability also is a key factor why certain companies go for SaaS-based products. SaaS-based products are easily scalable and hence without any overhead, it can be adopted across large enterprises.5.3. SecurityThese days a lot of enterprises are emphasising on the need for security in the DevOps tooling space. Hence enterprise versions by various tooling companies have taken special care towards addressing these security-related issues. Thus enterprise versions are comparatively more preferred in comparison with that of open source solutions. Saying so this doesn't mean that all open source DevOps tools have security vulnerabilities. Certain open source DevOps tools fair much better than available enterprise versions5.4. Technical know howThis people dimension is one of the factors that is typically overlooked by enterprises. Knowing the skill levels and capability of team members is a key towards choosing the right tool. Often the tools available in the market wouldn't work out of the box and would need a substantial level of customisation to smoothly integrate with existing systems and workflows. Also, certain tools require a certain specific skill set towards configuration and customisation. Typical eg. is Chef, which is chosen by developers who are comfortable in ruby language whereas Puppet is preferred by system admins as it does not require much of programming skills.5.5. ReliabilityLast but not the least, reliability is extremely crucial for any successful tool adoption. Most of the tools available in the market, both enterprise and open source needs to be checked using this quality wheel. Tools should be reliable even during large scale and complex operational conditions. ConclusionIn this paper, we discussed the what, why, and how of DevOps.We also deep dived into various tool categories and tools available across the spectrum in today's DevOps market. Tools are definitely the key ingredients in successful DevOps adoption but saying so a lot of companies only invest in tool part without focusing on cultural and people dimensions. In order for tools to bear fruit its vital that the people operating and analysing the tools/data understand and realise the true spirit of DevOps. To conclude, would like to resonate with the wise words “yes, we need all the tools that can help us, but just tools will not help us get there!”.

How to Become a DevOps Engineer

Who is DevOps engineer?        DevOps engineers are a group of influential individuals who encapsulates depth of knowledge and years of hands-on experience around a wide variety of open source technologies and tools. They come with core attributes which involve an ability to code and script, data management skills as well as a strong focus on business outcomes. They are rightly called “Special Forces” who hold core attributes around collaboration, open communication and reaching across functional borders.DevOps engineer always shows interest and comfort working with frequent, incremental code testing and deployment. With a strong grasp of automation tools, these individuals are expected to move the business quicker and forward, at the same time giving a stronger technology advantage. In nutshell, a DevOps engineer must have a solid interest in scripting and coding,  skill in taking care of deployment automation, framework computerization and capacity to deal with the version control system.Qualities of a DevOps Engineer Collated below are the characteristics/attributes of the DevOps Engineer.Experience in a wide range of open source tools and techniquesA Broad knowledge on Sysadmin and Ops rolesExpertise in software coding, testing, and deploymentExperiences on DevOps Automation tools like Ansible, Puppet, and ChefExperience in Continuous Integration, Delivery & DeploymentIndustry-wide experience in implementation of  DevOps solutions for team collaborationsA firm knowledge of the various computer programming languagesGood awareness in Agile Methodology of Project ManagementA Forward-thinker with an ability to connect the technical and business goals     Demand for people with DevOps skills is growing rapidly because businesses get great results from DevOps. Organizations using DevOps practices are overwhelmingly high-functioning: They deploy code up to 30 times more frequently than their competitors, and 50 percent fewer of their deployments fail.What exactly DevOps Engineer do?DevOps is not a way to get developers doing operational tasks so that you can get rid of the operations team and vice versa.  Rather it is a way of working that encourages the Development and Operations teams to work together in a highly collaborative way towards the same goal. In nutshell, DevOps integrates developers and operations team to improve collaboration and productivity.The main goal of DevOps is not only to increase the product’s quality to a greater extent but also to increase the collaboration of Dev and Ops team as well so that the workflow within the organization becomes smoother & efficient at the same time.DevOps Engineer has an end-to-end responsibility of the Application (Software) right from gathering the requirement to development, to testing, to infrastructure deployment, to application deployment and finally monitoring & gathering feedback from the end users, then again implementing the changes. These engineers spend more time researching new technologies that will improve efficiency and effectiveness.They Implement highly scalable applications and integrate infrastructure builds with application deployment processes. Let us spend some time in understanding the list of most important DevOps Engineers’ roles and responsibilities.1) The first and foremost critical role of a DevOps Engineer is to be an effective communicator i.e Soft Skills. A DevOps Engineer is required to be a bridge between the silos and bring different teams together to work towards a common goal. Hence, you can think of DevOps Engineers as “IT Project Managers”. They typically work on a DevOps team with other professionals in a similar role, each managing their own piece of the infrastructure puzzle.2) The second critical role of DevOps Engineer is to be Expert Collaborators. This is because their role requires them to build upon the work of their counterparts on the development and IT teams to scale cloud programs, create workflow processes, assign tenants and more.3) Thirdly, they can be rightly called “Mentors” as they spend most of the time in mentoring and educating software developers and architecture teams within an organization on how to create software that is easily scalable. They also collaborate with IT and security teams to ensure quality releases.Next, they need to be a “customer-service oriented” individuals. The DevOps Engineer is a customer-service oriented, team player who can emerge from a number of different work and educational backgrounds, but through their experience has developed the right skillset to move into DevOps.The DevOps Engineer is an important IT team member because they work with an internal customer. This includes QC personnel, software and application developers, project managers and project stakeholders usually from within the same organization. Even though they rarely work with external customers or end-users, but they keep close eye on  a “customer first” mindset to satisfy the needs of their internal clients.Not to miss out, DevOps engineer holds broad knowledge and experience with Infrastructure automation tools. A key element of DevOps is automation.  A lot of the manual tasks performed by the more traditional system administrator and engineering roles can be automated by using scripting languages like Python, Ruby, Bash, Shell, Node.js.

The goal should be for zero manual intervention from source code management to deployment state, i.e. Continuous Integration, Continuous Delivery and Continuous Deployment.#5 - Bigger Picture & Customer FocusWhile the strong focus on coding chops makes software engineering a natural path to a career in DevOps, the challenge for candidates who are coming from this world is that they need to be able to prove that they can look outside their immediate team and project. DevOps engineers are responsible for facilitating collaboration and communication between the Development and IT teams within an organization, so to succeed in an interview, you’ll need to be able to demonstrate your understanding of how disparate parts of the technical organization fit and work together.In nutshell, all you need are the list of tools and technologies listed below -Source Control (like Git, Bitbucket, Svn, VSTS etc)Continuous Integration (like Jenkins, Bamboo, VSTS )Infrastructure Automation (like Puppet, Chef, Ansible)Deployment Automation & Orchestration (like Jenkins, VSTS, Octopus Deploy)Container Concepts (LXD, Docker)Orchestration (Kubernetes, Mesos, Swarm)Cloud (like AWS, Azure, Google Cloud, Openstack)What are DevOps certifications available in the market?
