摘要:
Embodiments of the invention relate to handling failures in a cluster of computer resources. The resources are represented as nodes in a dependency graph in which some nodes are articulation points and the removal of any articulation point due to a resource failure results in a disconnected graph. The embodiments perform a failover when a resource corresponding to an articulation point fails. The failover is to a local resource if the failed resource does not affect all local resources. The failover is to a remote resource if no local resource can meet all resource requirements of the failed resource, and to a remote resource running in a degraded mode if the remote resource cannot meet all of the requirements.
