Oracle recently published details of the Oracle Optimized Solution for Enterprise Cloud Infrastructure, a set of recommendations and best practices for building Oracle certified private cloud infrastructure stacks. It includes optimized configurations for applications and virtual machine templates.

The stacks consist of Sun Blade servers, Oracle Solaris or Oracle Linux, Oracle VM Server, Oracle Enterprise Manager Ops Center, Oracle/Sun ZFS storage solutions and Sun networking technology.

Unlike a projects like OpenStack and Eucalyptus, which provide software for managing a cloud infrastructure, Oracle is promoting an entire stack including hardware and software. It's probably most comparable to HP CloudSystemor Cisco Unified Computing System.

Last year Oracle submitted a proposal for a private cloud management API called the Oracle Cloud API to the Distributed Management Task Force (DMTF).
