Elastic cloud infrastructure startup Cloudscaling has raised $10 million in its second round of funding so it can keep growing at a quick clip and innovating its cloud technology.

San Francisco-based Cloudscaling was founded in 2006 and claims to be “the leader in elastic cloud infrastructure.” Its core product is the Open Cloud System, an OpenStack-powered cloud infrastructure application that can give companies the same benefits of cloud infrastructure providers like Amazon Web Services and Rackspace. Cloudscaling’s solution is deployable in a client’s data center under an IT team’s control. It can also run its solution on Amazon and Google’s public clouds if a customer wants to do so.

In April, Cloudscaling announced version 2.5 of Open Cloud System. Some of its newest customer wins include LivingSocial, EVault, Ubisoft, and DataFort.

The new funding was provided by prior investor Trinity Ventures and new investors Juniper Networks and Seagate. Previously, Cloudscaling raised $4 million back in Sept. 2011.

“This financing round caps a tremendous year of momentum for the company,” Cloudscaling CEO Michael Grant said in a statement. “That momentum affirms the voice of the market, clearly stating that customers want more than OpenStack. They want an on-premise, OpenStack-based private or public cloud turnkey system solution that delivers architectural and behavioral fidelity with major public clouds like Amazon Web Services. Our Open Cloud System product delivers on that need to enable hybrid cloud application deployments that span private and public cloud services.”
