In this session, we outline the development of a policy-driven scheduler that allows the Nova administrator (as well as Nova tenant administrators) to control placement decisions by writing policy statements that dictate which VMs or containers can be placed on which hosts. The DevOps-friendly, policy-driven scheduler plugs into the existing scheduler framework, to enable people to easily and quickly express custom scheduling rules and constraints, and at the same time provide assurances related to performance, security, and data integrity.
