1. A method for balancing use of resources between nodes of a multi-node system, the method comprising the steps of:

  • detecting a service-level violation on a first node from a set of nodes in the multi-node system;

    wherein the set of nodes hosts a multi-node server that includes a first server instance on the first node;

    determining a first number of sessions running on the first server instance to migrate to a second server instance of the multi-node server on a second node of said set of nodes;

    migrating at least a portion of said first number of sessions to said second server instance;

    determining whether said service-level violation on the first node persists; and

    if said service-level violation persists, repeating the step of determining a first number of instances and the step of migrating.
