On-demand global server load balancing system and method of use

A method of routing requests in a network, comprising:

• computing a performance metric for at least any one of a site, a virtual cluster, and a server of a plurality of servers;
• and
• routing a request to at least any one of the site, the virtual cluster and the server based on the performance metric for balancing workload among the plurality of servers,
• wherein the performance metric includes a response time metric associated with the at least any one of a site, a virtual cluster, and a server of a plurality of servers.

A system for routing requests in a network, comprising at least one component to:

• measure performance of one or more servers in one or more virtual clusters;
• generate a performance metric for each of the one or more servers;
• and
• route a request to one of the one or more servers based on the computed performance metric to balance a workload among the one or more servers.

A system for balancing workload, comprising:

• means for collecting performance measurements for at least any one of a server, a virtual cluster and a site;
• means for generating at least any one of a server performance metric, a virtual cluster metric and a site performance statistic based on the performance measurements;
• and
• means for routing a request to the server based on at least any one of the server performance metric, the virtual cluster metric, the site performance statistic and any combination thereof.

A method to provide a service for establishing a computing infrastructure, comprising the steps of:

• combining computer readable code with a computing platform;
• computing a performance metric for at least any one of a site, a virtual cluster, and a server of a plurality of servers of the combined computing platform;
• and
• routing a request to at least any one of the site, the virtual cluster and the server based on the performance metric for balancing workload among the plurality of servers,
• wherein the performance metric includes a response time metric associated with the at least any one of a site, a virtual cluster and a server of the plurality of servers.

A computer program product comprising a computer usable medium having readable program code embodied in the medium, the computer program product includes at least one component to:
