Abstract:
1. An apparatus comprising: a plurality of compute nodes; and a load balancer in communication with the plurality of compute nodes and programmed to: receive a connection request from a first client computing device and receive a corresponding first persistence identifier for a virtualized operating system instance from the first client computing device, the virtualized operating system instance is to enable the first client computing device to execute application programs on a first one of the compute nodes; restore, on the first compute node, a stored virtualized operating system instance when the first persistence identifier is associated with the stored virtualized operating system instance; initiate, on the first compute node, a new virtualized operating system instance when the first persistence identifier is not associated with any stored virtualized operating system instance; assign the connection request from the first client computing device to the first compute node; receive a connection disable request from the first compute node, wherein the connection disable request identifies the first compute node; and store a state change associated with the stored virtualized operating system instance.
