From Tools to Culture: How DevOps is Revolutionizing Business Practices
DevOps: What is it?
DevOps, to put it simply, is about breaking down the boundaries that have historically existed between development and operations teams. Development and operations teams collaborate across the whole software application life cycle, from development and testing to deployment and operations, when using a DevOps paradigm.
DevOps Lifecycle
DevOps can be implemented in 3 phases:
Phase 1: Automated Testing
Phase 2: Continuous Integration
Phase 3: Continuous Delivery
- Automated Testing
The cornerstones of DevOps proficiency are automated testing and the agile methodology. This required developing tests inside the code so that each code modification could be assessed based on whether the test passed or failed.
- Continuous Integration
All of the testing is automated after we have sufficient code coverage for testing. One of the most often utilized technologies for continuous integration implementation is Jenkins. Several servers are used in the background to test the code and make sure it goes through all feasible iterations to see if any bugs can be found. At the conclusion of that process, Jenkins will then produce a report with information like the code coverage and succeeded or failed tests.
- Continuous delivery
The true business value is found at this phase. Writing code in manageable chunks — such as new features or bug fixes — that are then merged, tested, watched over, and released makes up the foundation.
The key areas are: Version Control, Continuous Integration Systems, Build, Test, you’ll need an Artifact repository such as (AWS S3, CloudRepo, Nexus, Artifactory, Docker Hub) and Deployment. Using version control (example: Git, SVN, etc.) and source code management (example: GitHub, Bitbucket, Subversion, Mercurial, CodeCommit, etc.), we commit code changes and can view the entire history of all changes ever made.
