Various embodiments of a system and method for diminishing workload imbalance across multiple database systems are described. Embodiments may include a resource balancer configured to, for each of a multiple database systems hosting database resources assigned to different user entities, generate a system usage score for that database system based on database usage scores of respective database resources hosted by that database system. Each usage score of a given database resource may indicate a quantity of work performed by the respective database system to process one or more requests directed to that database resource. The resource balancer may also be configured to generate one or more instructions to move a database resource from a first database system having a first system usage score to a second database system having a smaller system usage score in order to diminish an imbalance of workload across the database systems.
