On Thursday, Internap launched its Open Public Cloud compute product and subsequently claimed stake to the hotly contested title of “first commercial deployment of the OpenStack cloud computing platform.” In its press release, Internap noted that its Open Public Cloud delivers “high-performance, on-demand provisioning and scaling of enterprise computing capacity to meet changing web and application demands.” Additional features of the Open Public Cloud include an easy to use management interface, APIs and use of the Xen Cloud Platform. Internap’s Open Public Cloud platform is built upon the Cactus release of OpenStack and hence has yet to incorporate the latest enhancements to OpenStack specified in its Diablo release. Internap joins Dell, Citrix, Piston Cloud Computing and Nebula in laying claim to the first commercial grade deployment of OpenStack cloud computing software. In late September, Piston Cloud Computing launched an enterprise grade deployment of OpenStack with its pentOS offering for private clouds.
