Those choices "are indicative of what they are trying to accomplish," said Forrester Research analyst John Rymer. "They want the enterprise crowd."

Many Forrester clients are looking to the cloud but want to build traditional transactional applications, versus Web applications, Rymer said. The Silver platform seems "pretty comprehensive" to that end, he added.

Tibco Silver will be available in form beginning June 30. The company plans to take its time fine tuning the product -- perhaps six months -- before a general release.

"We want really good feedback because this is an emerging market," Menon said.

Silver will initially be available on Amazon Web Services, but Tibco will look to add other cloud computing infrastructure providers later, Menon said.
