Oracle Corporation (NYSE:ORCL) is continuing its march into the "cloud." On Tuesday, the computer database company announced that it has agreed to buy Corente, a leading provider of software-defined networking (SDN) technology for wide area networks (WANs), for an undisclosed sum.

As Oracle explained in a statement on the purchase, Corente's software "accelerates deployment of cloud-based applications and services by allowing customers to provision and manage global private networks connecting to any site, in a secure, centralized and simple manner."

Corente does this by managing the distribution of software applications over networks. Oracle says that it is buying the company in order to marry its own technology portfolio with Corente's expertise in delivering these products to customers via the cloud.

In a letter to the company's customers and partners, Oracle Chief Corporate Architect Edward Screven said Corente deployments have " "dramatically decreased time to deployment of cloud-based applications and services, and increased security and manageability across the enterprise ecosystem."

Oracle shares rose 0.5% in Tuesday morning trading.
