BALANCING MAINFRAME AND DISTRIBUTED WORKLOADS BASED ON PERFORMANCE AND COSTS

In an approach for balancing mainframe and distributed workloads, a processor receives a request to allocate an application workload to a mainframe platform and a distributed computing platform. The application workload includes a plurality of work units. A processor collects performance and cost data associated with the application workload, the mainframe platform, and the distributed computing platform. A processor determines the mainframe platform and the distributed computing platform for the plurality of work units of the application workload, based on the analysis of the performance and cost data. A processor allocates the plurality of work units of the application workload to run on the mainframe platform and the distributed computing platform respectively to balance performance and cost in real time.
