Utility computing technology developer 3Tera reported on Wednesday that is using the Web 2.0 Expo event in San Francisco this week to introduce its Cloudware architecture “for cloud computing without compromise,” offering access to hosted computing power based on the company’s AppLogic grid hosting operating system.

The Cloudware architecture, says 3Tera, incorporates storage, computing, connectivity, security – the resources required to build and run applications in the cloud, along the lines of a product like Amazon’s EC2 or S3 services, the popular reference point for cloud computing services.

The company says Cloudware is “vendor agnostic,” meaning that the service is capable of supporting software from any third-party provider. Initially, it will support the most popular operating systems, including Linux, Solaris and Windows.

3Tera has been building its reputation as one of the marquee developers of technology for assembling grid-based computing platforms for application hosting and other implementations (in the press release’s language – the leading innovator of cloud computing technology and utility computing services), but there has been little indication that the company intended to support an infrastructure solution of its own before now.

The press release includes a quote from Todd Abrams, President and COO of Layered Technologies, the hosting company that has operated as the fairly flagship implementation of AppLogic. “With the introduction of Cloud Computing without Compromise, hosting your application in the cloud just became incredibly easier,” says Abrams. “Customers not only have the ability to choose their own operating system, middleware, security, vendors, location, etc., they also get their own personally customized virtual private data center.”

There’s no official indication in the announcement of where the hardware for the service is going to be hosted, but the close relationship and the apparent enthusiasm for a service that would seem to be in competition with its own Grid Layer service might at least hint at the possibility that Layered Tech is involved in the project.
