Cisco’s Wide Area Application Services (WAAS) appliances perform WAN optimization for locally hosting remote applications. They help reduce branch office IT costs by centralizing applications, such as Microsoft Windows Server 2008, in the data center. Cisco just unveiled a second generation of WAAS appliances that feature up to 2Gbps optimized WAN throughput, support for up to six virtual blades, and 150,000 TCP connections. Cisco also has a virtualized version of WAAS on its Unified Computing System blade servers; and an Application Control Engine for Layer 4 load-balancing and Layer 7 content-switching.
