Branch Cache (MS Elearning)

BranchCache operates in one of the following two modes, based on the cache location:




Hosted Cache. The Hosted Cache mode operates by deploying a computer that is running Windows Server 2008 R2 as a host in the branch office. Client computers are configured with the fully qualified domain name (FQDN) of the host computer so that they can retrieve content from the Hosted Cache when available. If the content is not available in the Hosted Cache, the content is retrieved from the content server by using a WAN link and then provided to the Hosted Cache, so that the subsequent client requests can get it from there.

Distributed Cache. You can configure BranchCache in the Distributed Cache mode for small branch offices. In this mode, local Windows 7 clients keep a copy of the content and make it available to other authorized clients that request the same data. This eliminates the need to have a server in the branch office. However, unlike the Hosted Cache mode, this configuration works across a single subnet only. In addition, clients that hibernate or disconnect from the network will not be able to provide content to other requesting clients.
