Google Cloud Build vs. Bamboo

Cloud Build is a service that executes your builds on Google Cloud. Cloud Build can import source code from a variety of repositories or Cloud Storage, execute a build to your specifications, and produce artifacts such as Docker containers or Java archives.

Bamboo is Atlassian's continuous delivery and release management tool. It offers first-class support for the "delivery" aspect of continuous delivery, tying automated builds, tests, and releases together in a single, integrated workflow. Bamboo gives developers, testers, build engineers, and system administrators a common space to work and share information – while still keeping sensitive operations like production deploys locked down. Got Git? Bamboo puts branches under test automatically, as well as merges and deploys them according to your team’s processes.
