  1. 1. DevOps – IaC Copyright © Thinknyx Technologies 1 Yogesh Raheja +91-9810344919 yogeshraheja07@gmail.com
  2. 2. Agenda • What is DevOps? • Why DevOps? • What is DevOps – IaC? • Why DevOps – IaC? • Essential tool set of DevOps – IaC • Introduction to GIT, Jenkins, Ansible and Docker • Live Demo • Q&A Copyright © Thinknyx Technologies 2
  3. 3. What is DevOps? • “DevOps is gaining momentum In IT Industry”. • “DevOps is a methodology to make IT a high-performing organization by breaking down the wall of confusion between Dev and Ops together with structure framework” • DevOps is not a technology., it’s a frame work, just a mindset change, a cultural difference, and an effective way of communication and collaboration between different cross functional teams (Dev[development] + Ops[Operations]) to know the loopholes in the product lifecycle process. • DevOps is a culture for Integration, Collaboration and Communication between different cross functional teams (including ops) for Continuous delivery. • DevOps encourages Operations to participate early in the Development cycle so that products are designed to be easily deployable and maintainable.

  4. 4. What is DevOps? • It is a collection of tools, such as Git, Jenkins, Sonar, Nexus, Docker, Ansible, Salt, Chef, Puppet and many more. • It is a collection of tools/technologies and processes to deliver quality services. • It is a movement to respond faster to the market. • It is a movement to delivery quality service faster with the right mix of collaboration between the Development and Operations teams.

  8. 8. Copyright © Thinknyx Technologies What is DevOps - IaC • IaC – Stands for Infrastructure as Code, evolved with the rise of DevOps Framework. • IaC is “configuring and maintaining” infrastructure activities (like os/db/application/network/firewall/DNS any other infra domain deployments, configurations and maintenance) in the form of codes. • Code-based files gives the flexibility to replicate the changes from days or hours to within a minutes or seconds. • This makes the product development and Release Management lifecycle very fast so that the organizations can launch their products and services in the market in a very short duration of time. 8
  9. 9. Copyright © Thinknyx Technologies Why DevOps – IaC? • The minor changes can be launched in a few minutes without downtime or with minimal downtime. • The beauty of Infrastructure as a Code (IaC) lies in its very : - descriptive nature - straight -forward execution - complete transparent nature • This change will help to bring Product Development (Waterfall, Agile, Lean) and Infrastructure methodologies (ITIL/ITSM) close to each other. • This closeness will result in faster product delivery and hence to the Organizational growth. 9

  11. 11. DevOps – Git (Version Control System) Copyright © Thinknyx Technologies 11 Yogesh Raheja +91-9810344919 yogeshraheja07@gmail.com
  12. 12. What is Version Control System 12 • As name states Version Control System is the “Management of changes to anything”. • Version Control is way of storing files in central location accessible to all team members and enabling them to keep track of changes being done in the source code by whom, when & why. It also help teams to recover from some inevitable circumstances. Copyright © Thinknyx Technologies
  13. 13. Never mind merging. It's not an SCM, it's a distribution and archival mechanism. I bet you could make a reasonable SCM on top of it, though. Another way of looking at it is to say that it's really a content-addressable file system, used to track directory trees. Linus Torvalds, 7 Apr 2005 13 GIT is not a SCM Copyright © Thinknyx Technologies
  14. 14. • Why Git: - Branching: gives developers a great flexibility to work on a replica of master branch. - Distributed Architecture: The main advantage of DVCS is “no requirement of network connections to central repository” while development of a product. - Open-Source: Free to use. - Integration with CI: Gives faster product life cycle with even more faster minor changes. 14 Why GIT Copyright © Thinknyx Technologies
  15. 15. BitBucket/GitHub/GitLab • What is Bitbucket /GitHub/Gitlab?. • Bitbucket is a Git solution for professional teams. In simple layman language its a UI for Git, offered by Atlassian, similarly we have different available UI solutions from Github (most famous) and Gitlab. • Host in the cloud: free for small teams (till 5 users) and paid for larger teams. • Host on Your server: One-Time pay for most solutions. • Visit “https://bitbucket.org/” and click “Get Started” to sign up for free account. • Visit “https://github.com/” for Github details Copyright © Thinknyx Technologies 15
  16. 16. DevOps – CI with Jenkins Copyright © Thinknyx Technologies 16 Yogesh Raheja +91-9810344919 yogeshraheja07@gmail.com
  17. 17. What is Continuous Integration • In Simple term Continuous Integration is a term which means “checking the compatibility of a change you have made with the remaining code base or modules of an application or to check the impact of that change on the application functionality”. • Continuous Integration is not helping us in fixing the bugs but it helps us to Identify those bugs in the early phases of a development lifecycle and with much faster rate. • Continuous Integration is not the sole responsibility of the developers but every individual working in the team is responsible for the Healthy Continuous Integration. Copyright © Thinknyx Technologies 17
  18. 18. Jenkins History • Jenkins was originally developed as the Hudson project. Hudson’s creation started in summer of 2004 at Sun Microsystems. Kohsuke Kawaguchi, the current CTO of CloudBees, “A Company providing Enterprise Level Support for Jenkins, when he was working with Sun Micro Systems” • Certain clashes between Sun Micro Systems and Hudson Community for the Management of the Project • Today Jenkins is the most used Continuous Integration tool in the market, which provide variety of functions to run with the help of large Jenkins Community. Copyright © Thinknyx Technologies 18
  19. 19. Brief about Jenkins • An Open Source CI Server with MIT (Massachusetts Institute of Technology)Licensing Large Community Base • More than 150,000 installations as on Dec, 2016 • More than 1300 plug-in support which make to compatible with almost every delivery tool available in market • Annual meet-up with the Jenkins World • CloudBees is the biggest promoter and Contributor of Jenkins Community and also provide Enterprise Support for Jenkins • Jenkins is a self-contained, open source automation server which can be used to automate all sorts of tasks related to building, testing, and deploying software.
