System and method for selectively hibernating and restarting a node of an application instance

Abstract:

A node of an application instance in a distributed computing environment can be selectively hibernated and the execution of the node selectively restarted by first detecting a condition of the node that satisfies a criterion for hibernating the node. The node may then be hibernated by suspending execution of the node on a server and initiating execution of a listener. The listener can use a network port that the node used before the execution of the node was suspended. At a later time, a request from a client to the application instance can be received by the listener. The request can be a request to restart execution of the node. Responsive to the request and a determination that the server has a predefined amount of resources for permitting execution of the node, the execution of the node on the server can be restarted.
