WS-Management Consistent management of multi-vendor systems Basic operations across compliant platforms Basic operation across OS states Scale down Support low-footprint management controllers Support operations in DMZ Use firewall-friendly transports Data model neutral Map to existing Common Information Model (CIM) Support new System Definition Model (SDM) Inspection of management resources Network discovery is out of scope

WS-Transfer Basic idea: Get/Put the representation of a Web Service resource Operations: Get  resource representation Put Create  new resource Destroy Best-effort semantics

WS-Eventing Basic idea: Service-initiated means of communication with clients Subscription operations: Subscribe  subscription context RenewUnsubscribe Subscription End (abnormal termination) Notification messages Extensible set of delivery modes

WS-Enumeration Basic idea: Logical cursor for a sequence of data items Operations: Enumerate  enumeration context Pull  data items RenewGetStatusRelease EnumerationEnd (abnormal termination)
