Summary
In this module, you have learned about the importance of source control and version control in DevOps. These practices are crucial for achieving continuous integration and infrastructure as code. Transitioning to a distributed version control model like Git is recommended, especially if using GitHub for software lifecycle management. Git allows for tracking changes, creating branches, merging branches, collaborating with multiple developers, and automating processes like continuous integration and deployment.
The main takeaways from this module are that version control systems can be categorized as centralized or distributed, with Git being the most popular choice for DevOps environments. GitHub is a cloud-based service that hosts Git repositories and provides collaboration tools. The GitHub flow process helps streamline updates to GitHub-hosted projects. Continuous integration is a key component of DevOps that promotes collaboration and early detection of code quality issues. Shift-left testing involves moving testing activities as early as possible in the development phase to improve code quality and minimize operational risk. It includes unit tests, smoke tests, integration tests, and acceptance tests. Shift-left security is also important, integrating security activities early in the software lifecycle and continuing throughout development.
