Some embodiments provide a method. The method interfaces with several nodes of a hosting system to collect statistics that includes available resources of each node for hosting virtual machines. The method identifies a set of nodes with sufficient available resources to host a configuration for a virtual machine based on the collected statistics. The method determines an optimal node from the set of nodes that hosts the configuration with a particular set of performance parameters that yields improved performance than when hosting the configuration using any of the other nodes in the set of nodes. The method deploys the configuration for the virtual machine to the optimal node.
