Publication number: 20240419428Abstract: Updates are managed across partitions in a distributed cloud allocation system. Updates are managed in a variety of dimensions, e.g., by partition, time, or upgrade domain, to maintain a sufficient number of allocator instances to maintain service. An update service may receive, organize, schedule, and deliver updates to VM allocator instances to limit service disruptions. Updates may be aggregated based on partition scope. Updates to one or more partitions may be batched in a single update. Delivery and timing of updates may be configurable on a per partition basis. Allocator instances may receive batched updates at the same or different times. An update service may dynamically adapt to prevailing service conditions if an essential update is in progress and/or request demand is above a threshold.Type: ApplicationFiled: June 13, 2023Publication date: December 19, 2024Inventors: Kyung Hoon SEO, Abhisek PAN, Robert Warren GRUEN, Yaswanth MALLEEDI, Ishai MENACHE, David Allen DION, Thomas MOSCIBRODA
