Abstract: A host recommendation service identifies a virtual machine. An analysis engine retrieves a plurality of metrics for each of a plurality of physical hosts available for executing the virtual machine. The plurality of metrics includes a current level of load on each of the plurality of physical hosts and a level of load on each of the plurality of physical hosts during a prior time period. The analysis engine also identifies a level of load placed on a physical host by the virtual machine during a prior time period. The analysis engine determines a level of priority associated with the metrics and assigns a score to each of the plurality of physical hosts. The host recommendation service transmits an identification of one of the plurality of physical hosts on which to execute the virtual machine.

Abstract: A method for evaluating historical metrics in selecting a physical host for execution of a virtual machine includes receiving, by a host recommendation service, an identification of a virtual machine and a request for an identification of a physical host on which to execute the virtual machine. The method includes retrieving, by an analysis engine in communication with the host recommendation service, a plurality of metrics for each of a plurality of physical hosts available for executing the virtual machine, the plurality of metrics including a first metric identifying a current level of load on each of the plurality of physical hosts and including a second metric identifying a level of load on each of the plurality of physical hosts during a time period prior to the current time period.
