CLUSTER CREATION AND MANAGEMENT FOR WORKLOAD RECOVERY

摘要

Aspects of the disclosure relate to managing migration of one or more applications from a primary computing device to recovery computing devices using a controller. Resource data that includes application resource requirements and resource capacities is monitored. An application exists as a single instance on the primary computing device. A recovery cluster for the application consisting of recovery computing devices is determined. A division of the application into a plurality of application instances is identified. In response to the resource data being updated, a new recovery cluster is determined. In response to the new recovery cluster, a new plurality of application instances is identified. Once a triggering event on the primary computing device is detected, the controller migrates the new application instances to the new recovery cluster. Other uses of the disclosure are possible.

1. A method for migrating an application operating in a single application instance on a primary computing device to a recovery cluster, comprising:
monitoring resource data that includes application resource requirements for the application and resource capacities of potential recovery computing devices; determining, based upon the resource capacities of the potential recovery computing devices, a first recovery cluster for the application that satisfies the application resource requirements; identifying, in response to determining a first recovery cluster, a first division of a single application instance into a first plurality of application instances; determining, in response to updates to the resource data, a second recovery cluster having recovery computing devices selected from the potential recovery computing devices; identifying, in response to determining a second recovery cluster, a second division of the single application instance into a second plurality of application instances; detecting a triggering event related to an ability of the primary computing device to process the application; and migrating the second plurality of application instances to the second recovery cluster in response to the triggering event.
