Abstract: In a data processing system having a processor and a memory protection unit (MPU), a method includes scheduling, in the processor, a new process to be executed; writing a process identifier (PID) corresponding to the new process into storage circuitry of the MPU; in response to updating the storage circuitry with the PID, configuring the MPU with region descriptors corresponding to the new process; configuring, by an operating system of the processor, the processor to execute the new process in parallel with the configuring the MPU with the region descriptors; and when the configuring the MPU is complete, giving control to the new process to execute on the processor.

Abstract: Methods comprise receiving a request to perform a predefined operation on at least one of a virtual machine and a workload executing on a host in a first cloud computing environment, identifying a set of credentials to access the first cloud computing environment, and initiating performance of the predefined operation on the at least one of the virtual machine and the workload, wherein the predefined operation comprises at least one of: (i) deleting, and (ii) shelving the at least one of the virtual machine and the workload.
