Improving Fault Tolerance in BizTalk Server 2006 by Using a Windows Server Cluster
Product(s): BizTalk Server 2006, Windows Server 2003
Microsoft BizTalk Server 2006 inherently provides high availability for the BizTalk application service when a BizTalk group is configured with multiple BizTalk servers. If a BizTalk group is configured with multiple BizTalk servers, high availability for the BizTalk application service is achieved by creating an instance of a BizTalk Host on multiple servers. In this scenario, if one of the host instances fails then host instances on other servers will take over processing duties for the failed host instance. While this functionality provides high availability for the BizTalk application service, it does not provide high availability for BizTalk Server dependencies and is subject to certain limitations.
A Microsoft Windows Server 2003 cluster provides high availability for services and applications by enabling fault tolerance. This white paper describes how to use a Windows Server cluster to provide high availability for key BizTalk Server components and BizTalk Server dependencies.
This white paper is intended to provide guidance to information technology (IT) professionals for the correct configuration of various BizTalk Server components and dependencies in a Windows Server cluster environment. It does not describe how to set up a cluster.
