RightScale, whose management platform that acts as an integrator for companies using public cloud resources, today announced its official support for the OpenStack project, and announced it will support customer deployments into Rackspace's OpenStack-powered cloud.

The moves represent further momentum for the OpenStack project and signal an acknowledgement by RightScale to include open source choices for customers.

"Enterprise interest in OpenStack continues to increase," says RightScale CEO Michael Crandell. Rackspace's open source cloud aligns closely to the OpenStack trunk code, which minimises proprietary extensions, he says.

RightScale already works as an integrator with a variety of other public and private cloud platforms, including Amazon Web Services, Windows Azure, Google Compute Engine, Datapipe, HP, Logicworks, SoftLayer and Tata. On the private cloud side, RightScale can be used to manage workloads on the OpenStack, CloudStack and Eucalyptus platforms, all of which are open source.

RightScale previously supported Rackspace's legacy cloud offering, but this summer Rackspace launched a new OpenStack-powered cloud, which it plans to devote most of its resources to advancing in the future. RightScale announced today support for Rackspace's OpenStack cloud.

In addition to supporting Rackspace's OpenStack efforts, RightScale has formally jumped on board to the larger OpenStack project, becoming a corporate sponsor of the project.

RightScale says its cloud management platform, which integrates with multiple clouds and allows users to view federated cloud deployments from a single dashboard, has already launched 4.7 million servers for customers since the company's founding in 2006.
