Variations discussed herein pertain to identifying a resource usage of applications in a first data center; and for the applications in the first data center, writing those usages to a database. Variations also pertain to identifying a resource usage of applications in a second data center; reading the first data center loads from the database; determining, from the read loads, which applications in the first data center will fail over to the second data center should the first data center fail. For those applications, computing a shadow load that represents predicted computing resource requirements of those applications in the second data center based read loads; and developing a failover resource allocation scheme from the shadow load and a current local resource load of the second data center such that the second data center can take on the resource usage load of those applications if the first data center goes offline.
