AT&T and CSC have agreed to partner to provide cloud computing services to enterprises such as financial services companies.

The announcement comes the same week a PricewaterhouseCoopers study of financial services executives found 71% plan to invest more in cloud computing this year and 50% plan to invest in private cloud technology. Also this week, IBM rolled out new Power- and x86-based servers to the company's Flex System intended to be used in private clouds.

Systems integrator CSC already offers a cloud computing service called BizCloud. It provides virtualized server, storage and networking technology, often installing the popular VBlock configuration of EMCstorage, Cisco servers and switches and VMWare virtualization software.

This is generally set up as a private cloud — virtualized computers, storage and network equipment that can be easily shared by applications, users and groups, set up on the customer's premises. Bank clients use BizCloud for such purposes as application development and testing and Big Data projects.

With today's agreement, CSC will now be able to offer customers the option of using BizCloud in one of AT&T's data centers, using the AT&T network. CSC is also implementing AT&T network equipment throughout its own IT infrastructure. The AT&T technology should help CSC provision new equipment faster and monitor it better, according to Gary Budzinski, executive vice president of CSC.

"Banks need a secure network and the bandwidth to move apps to the cloud," Budzinski says. "This is not a cost play but a growth play — clients are asking to migrate to a new set of technologies much quicker so business apps are completed faster."
