Improving Fault Tolerance in BizTalk Server by Using a Windows Server Cluster Microsoft Corporation Published: May 2009 Author: Trace Young Summary Microsoft BizTalk Server 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, host instances on other servers will take over processing duties for the failed host instance. Although 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. Windows Server 2008 failover cluster and Windows Server 2003 server cluster provide high availability for services and applications by enabling fault tolerance. This white paper provides guidance for information technology (IT) professionals on how to use a Windows Server 2008 failover cluster or Windows Server 2003 server cluster to provide high availability for key BizTalk Server components and dependencies.
