OpenLogic said today that its open-source PaaS offering can now be deployed by Rackspace Cloud users. CloudSwing is also becoming available via the Rackspace Cloud Tools catalog.

CloudSwing’s big attraction is that users can fully customize the various technology stacks while leveraging OpenLogic’s support for over 600 open source packs, as well as the platform’s cost monitoring capabilities.

Existing OpenLogic customers will now be able to run their apps on Rackspace Cloud, while the latter’s subscribers will be able to use CloudSwing in order to customize and monitor their existing deployments.

“The Rackspace Cloud and CloudSwing are both built to handle the highly-flexible and on-demand environments that enterprises need to deploy in the cloud,” said Ven Shanmugam, Senior Manager, Strategy and Corporate Development at Rackspace. “We welcome OpenLogic into our Cloud Tools community.”

The partnership with Rackspace is the second recent time OpenLogic expanded its PaaS’s support roster. Earlier this month we’ve learned that the company has teamed up with New Relic. The SaaS firm provides application performance monitoring on the browser and infrastructure sides, thus easily supplementing the cost management tools already included with CloudSwing.

The whole concept has earned OpenLogic’s offering a lot of early demand. It launched in October and has managed to triple the number of users in just 60 months, according to official data.

While OpenLogic fleshes out its PaaS, Rackspace is doing the same with OpenStack. The open-source cloud OS will be spun off to become the foundation of its own initiative in 2012, but Rackspace is, and will likely remain, heavily invested in the project it helped to get off the ground.  The company released Rackspace Cloud: Private Edition, a cloud service aimed at organizations operating medium to large private cloud deployments. The core offering, which is the Diablo release of OpenStack, is completely free.
