Business software maker Oracle has acquired privately owned Xsigo Systems, provider of network virtualisation technology for an undisclosed sum.

California-based Xsigo founded in 2004s provides software-defined networking technology which simplifies cloud infrastructure and operations by allowing customers to dynamically and flexibly connect any server to any network and storage.

The technology helps in increased asset utilisation and application performance while reducing cost, Oracle said.

The deal will help the company combine Xsigo’s network virtualisation application with Oracle VM for server virtualisation to deliver a complete set of virtualisation capabilities for cloud environments.

Oracle Systems executive vice president John Fowler said, "With Xsigo, customers can reduce the complexity and simplify management of their clouds by delivering compute, storage and network resources that can be dynamically reallocated on-demand."

Xsigo CEO Lloyd Carney said customers are focused on reducing costs and improving utilisation of their network.

"Virtualization of these resources allows customers to scale compute and storage for their public and private clouds while matching network capacity as demand dictates," Carney said.

Oracle had earlier this month had acquired social marketing company Involver and revealed a plan to acquire Skire which develops software to help companies plan and execute projects.

The company is in buying spree in past few months, acquired human resource software developer Taleo for $1.9bn and cloud based service company RightNow Technologies.
