Skytap, a company that provides virtual computing environments for application testing, announced that it brought in $7 million in a second round of funding from Ignition Partners, Madrona Venture Group and Washington Research Foundation. The new money will be used for product development and to bolster sales efforts, the Seattle-based company says.

Skytap specializes in delivering cloud services to companies that are actively developing and testing applications. Its technology can help lower hardware and software costs for these clients by allowing them to easily scale operations yet only pay for server resources when they are actually being used.

It raised $6 million in first-round funding in the summer of 2007 from Bezos Expeditions, in addition to Madrona, Ignition and WRF.
