Branch offices have unique management challenges.
A branch office typically has slow connectivity to the enterprise network and limited infrastructure for securing servers.
In addition, you need to back up data that you maintain in your remote branch offices, which is why organizations prefer to centralize data where possible.
Therefore, the challenge is to provide efficient access to network resources for users in branch offices.
BranchCache helps you overcome these problems by caching files so they do not have to be transferred repeatedly over the network.
BranchCache improves the responsiveness of common network applications that access intranet servers
across slow WAN links.
across slow WAN links.
Because BranchCache does not require additional infrastructure, you can improve the performance of remote networks by deploying Windows 7 or newer client computers, and by deploying Windows Server 2008 R2 or newer servers, and then enabling the BranchCache feature.
BranchCache maintains file and folder permissions to ensure that users only have access to files and
folders for which they have permission.
folders for which they have permission.
