In terms of benefits, I feel that many companies are moving to Bitbucket Server since it can be deployed on an on-premises model at a time when everything is being moved to the cloud.
Bitbucket Server efficiently integrates with JIRA, Bamboo, and Jenkins, enhancing workflow efficiency through seamless CI/CD capabilities. It ensures security and scalability with private repositories, though performance issues occur with large code pushes. Setup is straightforward, yet frequent patching and limited command line features challenge users. Maintenance is facilitated by fast deployment, but trunk-based development would benefit from ready-to-use integrations instead of relying on plugins. Stable code management aids reliable performance.
