High Availability for Message Queuing

Updated: June 25, 2007

Applies To: Windows Server 2008

Enhanced scalability and high availability is provided for Message Queuing through the use of Failover Clustering and web farm technologies such as a Network Load Balancing cluster, DNS round-robin distribution, or network address translation (NAT).

Fault tolerance is available for the Message Queuing and Message Queuing Triggers services by configuring these services in a cluster group using the High Availability Wizard. The High Availability Wizard is a component of the Failover Clustering feature that can be installed with Server Manager in Windows Server 2008 R2. Services or applications that are configured in a cluster group appear to network clients as a single, highly available system. For more information, see Message Queuing in Server Clusters.

To increase the availability and scalability of Web server resources, a Web farm is often deployed as a collection of independent servers, to which all HTTP incoming requests are directed. Network Load Balancing clusters, network address translation (NAT), and DNS round robin are some of the methods typically used to deploy Web farm capability.
