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.

Windows instance types will have additional costs associated with Microsoft licensing. Windows stemcell do not include actual Windows OS.
