A computer program product includes program instructions configured for execution by a processor to perform various operations. The operations include accessing a system resource database including, for each of a plurality of disaggregated computing hardware resources within a composable computing system, hardware characteristics that describe the disaggregated computing hardware resource, wherein the hardware characteristics include a physical location of the disaggregated computing hardware resource. The operations further include identifying a first workload request that requests performance of a first workload, identifying a physical location requirement for the first workload, selecting a subset of the disaggregated computing hardware resources to be included in a first computing subsystem for performance of the first workload in compliance with the physical location requirement for the first workload, provisioning of the first computing subsystem, and assigning the first computing subsystem to perform the first workload.
