Example resource provisioning systems and methods are described. In one implementation, an execution platform accesses multiple remote storage devices. The execution platform includes multiple virtual warehouses, each of which includes a cache to store data retrieved from the remote storage devices and a processor that is independent of the remote storage devices. A resource manager is coupled to the execution platform and monitors received data processing requests and resource utilization. The resource manager also determines whether additional virtual warehouses are needed based on the data processing requests and the resource utilization. If additional virtual warehouses are needed, the resource manager provisions a new virtual warehouse.
