How do companies ship code to production?
Step 1: The process starts with a product owner creating user stories based on requirements.
Step 2: The dev team picks up the user stories from the backlog and puts them into a sprint for a two-week dev cycle.
Step 3: The developers commit source code into the code repository Git.
Step 4: A build is triggered in Jenkins. The source code must pass unit tests, code coverage threshold, and gates in SonarQube.
Step 5: Once the build is successful, the build is stored in artifactory. Then the build is deployed into the dev environment.
Step 6: There might be multiple dev teams working on different features. The features need to be tested independently, so they are deployed to QA1 and QA2.
Step 7: The QA team picks up the new QA environments and performs QA testing, regression testing, and performance testing.
Steps 8: Once the QA builds pass the QA team’s verification, they are deployed to the UAT environment.
Step 9: If the UAT testing is successful, the builds become release candidates and will be deployed to the production environment on schedule.
Step 10: SRE (Site Reliability Engineering) team is responsible for prod monitoring.
