How to choose a cloud-based CI/CD platform

Hosting CI/CD in the cloud can both speed up interactions between development pipelines and source code repositories and make life easier for developers.

If your goals are high-velocity software development and frequent delivery of working builds to production, you need to automate at least part of the testing and delivery process. Ideally, that means implementing CI/CD pipelines for your projects, along with test suites to catch errors before customers see the software, and scripts that implement the steps of the pipelines.

Continuous integration (CI) is a methodology for automating software builds, packaging, and tests in a consistent way. CI helps to give a team some confidence that changes they check into source code version control will not break the build or introduce bugs into the software. The endpoint of CI is typically a completed check-in to the main branch of a software repository.

Continuous delivery (CD) automates the delivery of tested software to infrastructure environments. That doesn’t usually mean throwing it directly into production to see if customers complain. Typically, organizations start by pushing the build to a development environment. After the developers themselves beat on the new build and release it, it usually goes to a test environment, where it is used by a broader group of users (sometimes just dedicated internal testers, sometimes a larger cadre of users signed up for beta testing or “dog-fooding”) and monitored closely. Finally, if all goes well, the testers sign off and push the new version to a production environment.

At each stage of CD, there are options to revert quickly to an older build and generate bug report tickets for the developers to address in the new build. The goal is not to push lots of builds into production, but rather to continuously improve and enhance the software without introducing regressions. Another term for these practices is “devops.”
