Abstract
A traditional registry, such as a global UDDI server, is not designed to accommodate transitory devices, e.g., devices that may frequently attach and detach from a network, often-times without warning, such as virtual machines offering or desiring services that are periodically instantiated and then suspended or destroyed. To accommodate such transitory devices, a dynamic resource/service registry may be implemented that leverages lower-level protocols or state to determine appropriate registry updates to keep the registry state consistent with currently-active virtual machines. For example, a virtual machine monitor (VMM) may track creation and suspension or deletion of a virtual machine (VM), and resources advertised by the VM, where the VMM appropriately adds or removes registry entries for the VM as the state of the VM changes or provides hooks (e.g. notifications) or other instrumentation based on said state or protocols to enable other associated modules or agents (e.g. management modules or the registry) to take appropriate actions.
