Allocating resources during failure recovery is provided. A set of one or more service level agreement tiers are identified corresponding to a client workload that was being processed by a failed computing environment. A highest level tier is selected in the set of one or more service level agreement tiers. Recovery resources are allocated in a failover computing environment to the highest level tier sufficient to meet a service level agreement associated with the highest level tier. The highest level tier is recovered in the set of one or more service level agreement tiers using the recovery resources in the failover computing environment. In response to recovering the highest level tier, tier resources of the highest level tier are reduced to a steady state level of processing in the failover computing environment.
