Multi-layer QoS management in a distributed computing environment

A computer program product for multi-layer quality of service (QoS) management in a distributed computing environment, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• receiving a workload to run in the environment;
• identifying a workload quality of service (QoS) class for the workload;
• translating the workload QoS class to a storage level QoS class;
• scheduling the workload to run on a compute node of the environment;
• communicating the storage level QoS class to a workload execution manager of the compute node;
• communicating the storage level QoS class to one or more storage managers of the environment, the storage managers managing storage resources in the environment;
• extending, by the storage managers, the storage level QoS class to the storage resources to support the workload QoS class;
• monitoring, by the storage managers, for hot spots, wherein the hot spots indicate increased loading with particular QoS classes;
• notifying, by the storage managers, a workload scheduler of the hot spots;
• scheduling, by the workload scheduler, workloads to avoid the hot spots;
• notifying, by the workload scheduler, the storage managers which workloads have been rescheduled to non-hot spots;
• replicating, by the storage managers, data to the non-hot spots where the rescheduled workloads will run;
• and
• moving, by the storage managers, storage resources from non-hot spots to the hot spots.
