ST. LOUIS, Dec. 15 -- Savvis Inc., a global leader in outsourced managed computing and network infrastructure for IT applications, today announced a strategic alliance with GTSI Corp., a leading provider of information technology (IT) solutions to the federal government. Under the alliance, Savvis will become GTSI's preferred provider of a wide range of managed hosting and IT infrastructure services for the federal agencies that outsource their IT services to GTSI.

Facing growing power and datacenter space constraints, the federal government has been increasingly outsourcing its IT infrastructure requirements rather than owning and operating IT infrastructure internally. GTSI is the leading provider of IT solutions to the government and is evolving its business model to meet the growing need for outsourced and managed IT services.

Savvis provides a broad range of flexible IT infrastructure services including managed and colocation hosting, virtualized computing and storage services, managed networks, and managed security services to meet the requirements of government and commercial enterprises.

"We needed a strategic IT infrastructure provider who could support the growth in our managed IT services sales model," said Bill Weber, GTSI's senior vice president of Programs and Services. "After an extensive assessment of service providers, we selected Savvis as the preferred provider based on their IT infrastructure services expertise, strong government experience, and flexible services offering."

"GTSI is a well-recognized leader in providing IT technology solutions to the federal government and we are excited about the opportunity to work together with them as a preferred provider," said Phil Koen, CEO of Savvis. "Increasingly, government agencies are going outside their own walls to secure IT and hosting services and they will now benefit from the combination of GTSI expertise in government operations and our expertise in managed IT infrastructure services."

Savvis' IT infrastructure-as-a-service delivery model closely aligns with GTSI's Technology Lifecycle Management (TLM), a framework for government agencies in the acquisition, deployment, management, support, and disposal of technology to meet business objectives and budgets.

Encompassing more than 1.4 million square feet, Savvis operates 29 datacenters in the U.S., Europe, and Asia, including three in the Washington, D.C. federal marketplace. Savvis has been recognized as a Leader in the Gartner Magic Quadrant for North American Web Hosting since 2004.
