1. A method of managing memory of a control plane for services in a computer system, comprising: executing a service host process of the control plane on a software platform of the computer system, the service host process including runtime software configured to manage lifecycles of objects representing the services, the objects being associated with the service host process and being marked as available; determining an amount of memory in the computer system consumed by the objects; marking a plurality of the objects as paused in response to determining that the amount of memory consumed by the objects exceeds a threshold; storing at least a portion of a runtime context of each of the plurality of objects in storage of the computer system; and disassociating the plurality of objects from the service host process to reclaim the memory consumed by the objects.
