The battle for the cloud continues to heat up with HP announcing earlier today the latest addition to its portfolio of cloud related products and services. Called the HP Cloud Application PaaS, the offer fills a hole in its cloud portfolio in an area commonly referred to as Platform as a Service or PaaS. (blah blah blah) settling on Vancouver, British Columbia based ActiveState and its Stackato PaaS software. The HP Cloud Application PaaS will be a fundamental component of the HP Cloud (blah blah blah) and with this announcement HP’s Cloud grabs a potentially big technological advantage. Expect other cloud providers to do the same by quickly following HP’s lead of an integrated PaaS technology as key a differentiator. It’s also interesting to see that HP has selected ActiveState to form the core of its new PaaS offering. ActiveState’s Stackato is built atop VMware’s Cloudfoundry project, and is described as an application platform for creating your own private, secure, and flexible enterprise Platform-as-a-Service (PaaS) using any language on any stack on any cloud.
