Datacenter hardware reallocation through workload distribution optimization

A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a processor to cause the processor to perform operations enhancing a distributed system of a datacenter comprising:

• detecting, by a Hardware Management Component of the datacenter, a failure of a failed hardware in the datacenter;
• responsive to the detecting, determining by an Asset Manager Component, the Asset Manager Component extracting hardware data for the failed hardware by executing an application programming interface call on the failed hardware, a lead time for a replacement of the failed hardware;
• determining by injecting the hardware data into the Hardware Management Component to output a replacement decision based on a priority of a workload deployed on the failed hardware and the lead time;
• deciding by the Hardware Management Component whether to replace the failed hardware with a substitute hardware from a lower priority system of the datacenter based on the replacement decision;
• and
• adjusting by a Workload Controller Component the workload deployed on the failed hardware based on the replacement decision, the distributed system is enhanced wherein the workload of the failed hardware of the distributed system is dynamically reallocated from the failed hardware to the substitute hardware.
