Optimizing for infrastructure diversity constraints in resource placement

Abstract

A distributed system may implement optimizing for infrastructure diversity in resource placement. A placement request for a resource to be placed at one of multiple resource hosts respectively implemented at infrastructure units may be received. An evaluation of utilization data for the multiple resource hosts may be performed with regard to an infrastructure diversity constraint for placing resources at the infrastructure units. A selection of a resource host may be made based on the evaluation of the utilization data according to the infrastructure diversity constraint. In some embodiments to select the resource host, the effect of placing the resource on candidate resource hosts on an infrastructure-diverse capacity metric may be determined to score the candidate resource hosts. The resource may be placed at the selected resource host.
