Metadata driven workflow semantics for management operations

摘要

In general, in one aspect, the invention relates to a method for managing nodes in a cluster. The method includes obtaining metadata from controllers on a node, processing the metadata to obtain solution groups and a processing sequence of the solution groups, notifying a solution manager to initiate performance of pre-update tasks associated with the node, and performing, after the notifying, an update of the nodes in the cluster based on the processing sequence of the solution groups.
