Abstract: A resend operation of application-level messages by communicating control messages over a publish/subscribe channel. A sending module sends application-level original messages to recipients, and stores a copy of the original message in a store. A resend determination module determines, in the event of insufficient acknowledgement of the original message, whether the original message should be resent. If the original message should be resent, the resend determination module also publishes a control message that correlates to the original message. A resend module subscribes in a manner that results in the resend module receiving the control message, and uses the control message to determine that the corresponding original message should be resent, whereupon the original message may be resent using the copy of the original message in the store.

Abstract: A management system for a computer service may have a single set of interfaces through which a local or remote version of the service may be administered. The management system may include a discovery system that determines if a service is provided through a local or remote host and uses the appropriate routines or connections to perform each administrative task. The management system may include a single set of console interfaces, wizards or sequential interactive interfaces, dialog boxes, or other user interface mechanisms that may be used to control a local or remote version of a service.
