Abstract
A method, apparatus, and system are directed toward managing a system that includes a cluster and an external resource. The external resource may be part of a second cluster that is collocated on the same hardware platforms as the cluster. A proxy resource is used to enforce a dependency relationship between a native resource of the cluster and an external resource, such that a dependency with the proxy resource serves to enforce a dependency with the external resource. The cluster framework may maintain states of the proxy resource, including an offline state, an online-standby state, and an online state. The online-standby indicates that the proxy has been started, but it has not determined that the associated external resource is enabled. The proxy may determine whether the external resource is enabled or disabled and, in response, notify the cluster framework.
