Abstract:
1. A method to shift information technology workloads, the method comprising: obtaining, using a processor, demand profiles for the workloads in an information technology infrastructure, a respective demand profile representing resource utilization over time to support a respective workload; shifting, with the processor, one or more of the demand profiles in time, the one or more of the demand profiles being shifted in time based on different possible assignments of different ones of the workloads to resources of the information technology infrastructure; evaluating, with the processor, aggregations of the one or more of the demand profiles shifted in time to determine a plurality of different possible workload assignment configurations that meet a target demand profile for an aggregation of the workloads; aggregating the demand profiles shifted in time in accordance with a first one of the different possible workload assignment configurations to determine an aggregate workload demand profile; comparing the aggregate workload demand profile and the target demand profile to determine whether to keep the first one of the different possible workload assignment configurations; and using a selected one of the plurality of different possible workload assignment configurations to assign the workloads to the resources of the information technology infrastructure.
