Bamboo can be deployed on Windows, Mac or Linux and requires the Sun JDK 1.5 or later. Bamboo ships with an internal database for evaluation purposes but can be connected to MySQL, Postgres, Oracle or Microsoft SQL Server for production. For full details please see here.
Bamboo can connect to CVS, Perforce or Subversion repositories natively. In addition, there are free third-party plugins available for ClearCase, Mercurial and AccuRev, amongst others.
