Example resource management systems and methods are described. In one implementation, a resource manager is to be coupled to one or more virtual data warehouse instances that each comprise a plurality of computing resources. A resource manager receives a query directed to database data. The resource manager determines a plurality of tasks associated with the query. The resource manager distributes the plurality of tasks among the one or more virtual data warehouse instances to cause each computing resource of the plurality of computing resources of the one or more virtual data warehouse instances to process a respective task of the plurality of tasks. The resource manager receives results obtained from the processing of the plurality of tasks. The resource manager uses the results to respond to the query.
