  • Automated service configuration snapshots and fallback
    Patent number: 7970740
    Abstract: In general, in one aspect, the invention relates to a method for taking a snapshot of a service instance, including transitioning the service instance to a new state, determining whether to take the snapshot based on the new state, obtaining a property composition of the service instance, and taking the snapshot using the property composition, if the snapshot is to be taken.

  • Two-level service model in operating system partitions
    Patent number: 7526774
    Abstract: The present invention provides, in one embodiment, a multi-level service model operating system environment that may be partitioned into a global zone and one or more non-global zones to isolate processes from processes executing in association with other non-global zones under control of a single kernel instance. In one embodiment, the multi-level service model includes a virtual platform layer and an application layer. The virtual platform layer may include services and resources for supporting the zones, which can be made accessible to the zones in the form of a virtual platform. The application layer may comprise the non-global zones, including an application environment for maintaining a runtime state for the zone's processes and any zone-constructed objects, such as network connections and shared memory segments. In one embodiment, control and management of non-global zones can be provided by a system of states and transitions.

  • Methods and apparatus for representing application dependencies
    Patent number: 7490317
    Abstract: Methods and apparatus for representing application dependencies are disclosed. A software application is executed according to an associated state machine. A set of dependencies relationship rules indicates dependencies of a set of software applications upon the software application based upon the state of the software application. The set of dependencies relationship rules may be represented by a dependencies graph, where the software application and the set of software applications are each represented by a dependency node in the dependencies graph and each line connecting the software application with one of the set of software applications corresponds to one or more dependency statements indicating a change in state in one of the set of software applications in response to a change in state of the software application.
