Cloud application architectures, microservices, CI/CD (continuous integration, continuous development) pipelines, test automation, and infrastructure as code are all technologies that enable agile development and devops teams to deliver code to production frequently. They have taken software development from the days of quarterly releases and complex integrations to a modern era of continuous development.
Developers have always been concerned about how to manage the codebase to support frequent releases, developer productivity, feature development, and code refactoring to address technical debt. Github enables different development and branching paradigms, including feature branches, release branches, trunk-based development, and Gitflow workflow. Branching strategies structure what code goes into builds and thus can be used to control which features get deployed to end-users.
