A stemcell is a versioned Operating System image wrapped with IaaS specific packaging.

Typical stemcell contains bare minimum OS skeleton with few common utilities pre-installed, a BOSH Agent and few configuration files to make OS be securely configured by default.

Ubuntu Lucid, CentOS 6.x, and Ruby agent based stemcells are deprecated.
