OpenStack cloud builder Cloudscaling nets $10M from Juniper, Seagate and friends

Cloudscaling, a company that’s made its name actually building OpenStack clouds for real customers including Korea Telecom, just closed a $10 million Series B round including money from new backers Juniper Networks'(s jnpr) Junos Innovation Fund and Seagate(s stx). Trinity Ventures, an early investor, also participated.

The San Francisco-based company targets new applications that run on its technology but can also run in Amazon and Google public clouds as needed. Juniper is already partnering with Cloudscaling which is using Juniper’s Virtual Network Control in a Virtual Private Cloud (VPC) feature that maps to virtual private clouds in Amazon Web Services.

The funding, “affirms 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,” Cloudscaling CEO Michael Grant said in a statement.

It’s been a sort of rocky week for OpenStack. On Monday, Dell(s dell) surprised the ecosystem by deep-sixing plans to roll out an OpenStack-based public cloud.

Cloudscaling closed a $4 million Series A round in September 2011. Company CTO Randy Bias, pictured above right, is an OpenStack Foundation board member, and will talk about issues and benefits of cloud adoption at GigaOM’s Structure Europe in September.
