Providing optimized quality of service to prioritized virtual machines and applications based on quality of shared resources

摘要

Quality of service is provided to prioritized VMs and applications, based on the varied quality of different shared computing resources. Each VM or application has an associated priority. A quality rating is dynamically assigned to each shared computing resource. Requests for shared computing resources made by specific VMs or applications are received. For each specific received request, the current priority of the requesting VM or application is identified. In response to each received request, a specific shared computing resource is assigned to the specific requesting VM or application. This assignment is made based on the current priority of the requesting VM or application and the current quality rating of the shared computing resource, thereby providing quality of service to the requesting VM or application corresponding to its current priority.

1. A computer-implemented method comprising:
dynamically assigning a quality rating to each one of a plurality of shared computing resources, wherein
the quality rating quantifies a plurality of static and dynamic qualitative factors concerning the each one of the plurality of shared computing resources, andthe each one of the plurality of shared computing resources is accessible by one or more applications executed by one or more virtual machines executed by a physical computer; receiving one or more requests for a shared computing resource from one or more requesting applications, wherein
each of the one or more requesting applications is assigned a priority; identifying, for each of the one or more requests, the priority of the requesting application; and in response to the each of the one or more requests, assigning a shared computing resource to the requesting application, wherein
the assigning is based on the priority of the requesting application and the quality rating of the shared computing resource.
