At a multiple-subnet branch office that is configured for distributed cache mode, a file downloaded to one subnet cannot be shared with client computers on other subnets.
The cloud has enormous potential to reduce operational expenses and achieve new levels of scale, but moving workloads away from the people who depend on them can increase networking costs and hurt productivity.
Users expect high performance and don't care where their applications and data are hosted.
Distributed cache mode allows you to deploy Branch Cache with no additional hardware in branch offices.
If the branch office where you want to deploy Branch Cache contains additional infrastructure, such as one or more servers that are running other workloads, deploying Branch Cache in hosted cache mode is beneficial for the following reasons: Hosted cache mode increases the cache efficiency because content is available even if the client that originally requested and cached the data is offline.
Supported Web servers include computers that are running Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2 that have the Web Server (IIS) server role installed and that use Hypertext Transfer Protocol (HTTP) or HTTP Secure (HTTPS).
In addition, the Web server must have the Branch Cache feature installed.This topic, which is intended for Information Technology (IT) professionals, provides overview information about Branch Cache, including Branch Cache modes, features, capabilities, and the Branch Cache functionality that is available in different operating systems. If you are a system administrator, network or storage solution architect, or other IT professional, Branch Cache might interest you under the following circumstances: Branch Cache is a wide area network (WAN) bandwidth optimization technology that is included in some editions of the Windows Server 2016 and Windows 10 operating systems, as well as in some editions of Windows Server 2012 R2, Windows 8.1, Windows Server 2012, Windows 8, Windows Server 2008 R2 and Windows 7.To optimize WAN bandwidth when users access content on remote servers, Branch Cache fetches content from your main office or hosted cloud content servers and caches the content at branch office locations, allowing client computers at branch offices to access the content locally rather than over the WAN.Supported file servers include computers that are running Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2 that have the File Services server role and the Branch Cache for Network Files role service installed.These file servers use Server Message Block (SMB) to exchange information between computers.At branch offices, content is stored either on servers that are configured to host the cache or, when no server is available in the branch office, on client computers that are running Windows 10, Windows 8.1, Windows 8 or Windows 7.
