Problem BackgroundThin, expensive WAN links between main office and branch offices

High link utilization Poor application responsiveness Trend towards data centralization

4Customers SayWe are improving the efficiency of our branch offices and saving bandwidth by using BranchCache in Windows Server 2008 R2 and Windows 7, said Lukas Kucera, IT services manager of Lukoil CEEB, one of the largest integrated oil and gas companies in the world. Some of our smaller facilities, such as the office in Slovakia and the storage terminal in Belgium, have just five to 10 users, so its not efficient to deploy a file server on-site, but it consumes bandwidth to have them continually accessing files from the main servers. BranchCache is the perfect solution.Taking advantage of the BranchCache feature in Windows Server 2008 R2, we can spend $20,000 rather than $50,000 per year on bandwidth by postponing our expansion schedule.David Feng, IT Director, Sporton InternationalConvergent Computing (CCO) wanted to improve remote network access for its mobile users. Using the DirectAccess and BranchCache features in Windows Server 2008 R2 and Windows 7, CCO has simplified remote connection to its network and sped the downloading of important files. It has cut costs by eliminating its virtual private network and has seen a 43 percent savings in wide area network (WAN) bandwidth.5Solution Tenets6

The Hosted cache on Windows Server 2008 R2 provides the following featuresA centralized cache for Protocols: HTTP, SMB E2E encrypted/signed traffic: SSL, IPsec, SMB signing etcDoes not modify protocols; benefits from protocol optimizationsConfigurable size/location/persisted across reboots/flush-ableWorks across multiple subnetsAdmins can seed content by writing custom scriptsCan be a virtual workload in an appliance

Easy to deploy; clients are configured via policy

37To SummarizeBranchCache reduces WAN bandwidth consumed by end users for intranet based HTTP and SMB traffic and improves end user experience

BranchCache accelerates delivery of encrypted and signed content such as when using HTTPS, IPsec, SMB signing and at the same time ensures authorization of users by the server at the central office.

BranchCache doesnt require additional equipment in the branch offices and can be easily managed using existing systems management technology such as group policy

BranchCache has a vibrant and growing ecosystem giving customers the choice to pick a solution that works best for their needs
