Continuous integration and delivery using Atlassian Bamboo allows for: 1) Splitting build and deployment projects to support multiple environments with Bamboo plans, stages, jobs, and tasks organizing the build pipeline. 2) Releasing any version through deployment projects at the push of a button by ensuring every change is releasable. 3) Integrating Bamboo with other Atlassian tools like Jira and Bitbucket for tracking issues and source code.
