Abstract: A service method and associated system is provided. The method includes generating event types for events and services associated with the events. Virtual or physical machines associated with the services are provisioned and a message associated with a first event is published. The message is routed to a queue of a second service and the second service is notified of the message. The services are enabled and a selection for a sub-set of the services is received. The selection is enabled.

Abstract: Techniques, systems, and articles of manufacture for automatically propagating updates in a data center. A method includes dividing multiple virtual machines in a data center into one or more equivalence classes, wherein each equivalence class is based on a signature corresponding to an offline, online and/or manual update, automatically creating an offline and/or online virtual machine manifest for a first virtual machine of the multiple virtual machines based on one or more file system changes during the offline, online and/or manual update for the first virtual machine, wherein said manifest is applicable to each additional virtual machine in the same equivalence class as the first virtual machine, and applying the offline and/or online virtual machine manifest for the first virtual machine to the remaining multiple virtual machines in the same equivalence class to automatically update the remaining multiple virtual machines in the same equivalence class.

Abstract: Techniques, systems, and articles of manufacture for automated application reconfiguration. A method includes identifying, for each of one or more configuration files in a pre-configured source virtual machine, a corresponding configuration file in a target virtual machine, identifying one or more mis-configured and/or missing points of variability in the one or more identified configuration files in the target virtual machine based on information derived from the one or more configuration files in the source virtual machine, and reconfiguring the target virtual machine by replacing each identified mis-configured point of variability with a given value based on the information derived from the one or more configuration files in the source virtual machine, and adding each identified missing point of variability at a given location with a given value and a given format based on the information derived from the one or more configuration files in the source virtual machine.
