GitLab CI is the leading CI solution. No longer need a team of people to maintain the CI server and help dev with CI config. GitLab allows developers to easily create their own configuration, AutoDev Ops, Builds, text, and quality check projects automatically. Sophisticated cross-project flows that are essential for a micro services architecture. Multi-project pipeline graphs allow you to use organizational flows to connect different projects instead of a hierarchical top-down organization that is hard to maintain. Keep strict quality standards for production code with automatic testing and reporting.
Environments history allows you to see what is currently being deployed on your servers, and to access a detailed view for all the past deployments. From this list you can also re-deploy the current version, or even rollback an old stable one in case something went wrong.Documentation
