ST. LOUIS, Mo., — December 4, 2007 —SAVVIS, Inc. (NASDAQ: SVVS), a global leader in IT infrastructure services for business applications, today announced production and deployment of SAVVIS’ new Application Transport Network (ATN) based on the Cisco IP Next-Generation Network architecture. As part of a major network and data center upgrade (announced jointly with Cisco December 19, 2006), SAVVIS has now enhanced its global wide area network (WAN) and integrated it with its hosting area network (HAN) infrastructure resulting in a next generation managed application transport network that further virtualizes and optimizes the delivery of enterprise applications.

“As today’s enterprise applications grow more complex and delivery models migrate toward a software as-a-service approach, the underlying network infrastructure that supports these applications must respond,” said Ted Chamberlin, Research Director at Gartner. “Enterprises now require virtualized infrastructure services configured to each application’s unique needs to further optimize performance, scalability and delivery to end users. Vendors that can transport applications over infrastructure powered by virtualized delivery platforms on a utility basis will solve a growing customer pain point and take a leadership position in the market.”

The SAVVIS ATN is a Tier 1 Multiprotocol Label Switching (MPLS) network serving approximately 20 percent of the world’s Internet routes. It features the Cisco CRS-1 Carrier Routing System with Cisco IOS XR Software at the core, along with the Cisco XR 12000 Series Routers incorporating the Cisco Multi-Service Blade (MSB) as multi-service edge platforms. The CRS-1 and XR 12000 routers serve as access and integration points connecting SAVVIS’ network and data centers.

SAVVIS’ WAN enhancements include new core and edge routers that enable MPLS, high-speed metro Ethernet access, and enhanced end-to-end customer controlled QoS, which when combined with SAVVIS’ monitoring and management enables high performance Application Transport Services (ATS) for public and private network enterprise needs (announced separately today).

Enhancements to the HAN augment the WAN upgrade and feature the deployment of the Cisco Application Control Engine (ACE) Blade and Firewall Services Module that is now in production in 13 SAVVIS data centers. This integrated Virtual Services Switch features a 10G network fabric with GigE and 10G customer handoffs significantly improving load balancing, SSL acceleration and security services, as well as enhancing SAVVIS’ ability to provide a much broader range of virtualized utility services.

As part of the WAN and HAN integration, SAVVIS has deployed the Cisco Multi-Service Blade, which facilitates virtual firewalls and is integrated with the Cisco XR 12000 Series Router. This enhances security performance and flexibility for SAVVIS customers as it now enables a second generation of in-the-cloud, virtual firewalls. The new virtual firewalls enable improved customer QoS control, higher capacity, and more firewall features to better satisfy customer security requirements. The MSB also provides a platform for SAVVIS to deploy additional advanced defense-in-depth models, and greater return on investment to SAVVIS customers than conventional dedicated firewalls.

“Cisco and SAVVIS share a vision for delivering software as a service and for developing highly responsive IT infrastructure optimized for application performance and availability,” said Bob McIntyre, chief technical officer of the service provider technology group at Cisco. “The application of the Cisco IP Next-Generation Network architecture to SAVVIS’ network and hosting infrastructure enables the virtualization of advanced services and presents a compelling IT solution to business and government entities.”

“This is a milestone in the realization of SAVVIS’ vision for an integrated IT service delivery model, where data centers serve as nodes on a global network,” said Bryan Doerr, chief technical officer of SAVVIS. “Our advanced and integrated network and hosting services are positioned to improve enterprise application delivery by providing our customers with access to the latest technologies and virtualization platforms, fully integrated, and available as a service. Working with Cisco we have created a unique service provider model focused entirely on the needs of business and government applications making it possible for organizations of all sizes and missions to achieve high levels of availability, security, and control for ERP, CRM, B2B, eCommerce, and SaaS application types.”
