Patent ID: 8762339

Claim:
A method for implementing disaster recovery for an application, comprising: selecting a subscription backup site for the application from a plurality of sites, the subscription backup site being a primary host site for a separate set of applications and having a virtual space that is able to accommodate the workload requirements for the application; deflating the application to operate in a dormant state having a small fraction of resources allocated with respect to the workload requirements for the application, wherein the dormant state allows resources to be shared between the application and the separate set of applications, and the small fraction of resources is greater than zero; and in response to a disaster on a primary site of the application: pooling resources from a plurality of constituents of the subscription backup site to create resources for the application; reducing a resource entitlement of the separate set of applications to increase the created resources for the application in response to an insufficiency of the pooled resources, wherein the reducing includes reducing a non-critical workload of the separate set of applications before a reducing a critical workload of the separate set of applications; and inflating the application on the subscription backup site by allocating the created resources to enable the application to execute on the subscription backup site.
