Applications that run in a server cluster fall into one of four categories:
These types of applications do not interact with the server cluster at all but can still fail over. Failure detection is limited. The Cluster service protects these applications mainly against hardware failures.
These types of applications are characterized by superior failure detection. The Cluster service can protect these applications not only against hardware but also against software failures.
These types of applications, which include Cluster Administrator and Cluster.exe, allow administrators to manage and configure clusters. For more information, see Server cluster components.
Resource types provide customized cluster management and instrumentation for applications, services, and devices. For more information, see Resource types.
