Virtualization Layer in a Virtual Computing Infrastructure

摘要

A cloud computing environment having a plurality of computing nodes is described. The plurality of computing nodes may be organized into a plurality of clusters, each of the plurality of clusters including a cluster controller. A virtual computing environment is created on each of the plurality of computing nodes. Communication with the virtual computing environment is enabled. An authorization to service a launch plan is received from a user. The launch plan includes at least one instance to launch. Bandwidth information is requested from each of the cluster controllers of the plurality of clusters. A score is computed for each of the plurality of clusters that responded to the requested bandwidth information. The launch plan is assigned to a cluster from the plurality of clusters based on the computed scores.
