CloudSwing customers can use the platform to assemble software stacks of both open-source and commercial products for use on cloud infrastructure services such as Amazon EC2 (Elastic Compute Cloud).

They will gain more flexibility compared to commercial PaaS offerings such as Microsoft's Azure, which limit their ability to choose various components within the stack, said Kim Weins, senior vice president of marketing.

A trial edition of CloudSwing is now in private beta. It will be followed by a DevTest version with more features later this year. A Production Edition is set for release in early 2012, according to Weins.

While CloudSwing will feature a set of prebuilt "Smart Stacks," a set of Web-based tools will help developers easily swap individual parts in and out, according to OpenLogic.

CloudSwing stacks will be organized through a centralized portal that gives customers access to management tools for each component in one place. The service will also provide component-level monitoring capabilities that go beyond the CPU and memory usage metrics that public clouds typically provide.
