A method, system, and computer-readable storage device for selecting a heterogeneous platform configuration is described herein. In one aspect, a heterogeneous evaluation system may receive a platform configuration request from the tenant system. The platform configuration request can specify a job list and a quality of service metric. The heterogeneous evaluation system may then generate a heterogeneous platform configuration selection based on simulations of sub-lists formed from the job list. The heterogeneous platform configuration selection can specify a first platform configuration for a first duster and a second platform configuration for a second duster. The heterogeneous evaluation system can communicate the heterogeneous platform configuration selection to the tenant system.
