Providing High Availability
High availability is provided for a BizTalk Server environment by implementing redundancy for each functional component in the environment. Redundancy for a BizTalk Host can be accomplished by installing multiple computers running BizTalk Server in a BizTalk group and then configuring instances of the host to run on more than one of the computers running BizTalk Server in the group. Redundancy for other components in a BizTalk Server environment can be accomplished by configuring the components as resources in a Windows Server cluster. BizTalk Server also accommodates configuring BizTalk Hosts as resources in a Windows Server cluster, which is recommended to provide high availability for certain BizTalk adapters.
This section describes how to provide high availability for the functional components in a BizTalk Server environment.
