Autonomic service routing using observed resource requirement for self-optimization

A machine readable storage having stored thereon a computer program for routing service requests to service instances in a service providing infrastructure, the computer program comprising a routine set of instructions for causing the machine to perform the steps of:

• receiving a service request;
• computing resource vectors for at least two service hosts, each of said at least two service hosts having a corresponding service providing infrastructure;
• retrieving a resource model for said service request;
• matching said retrieved resource model to each of said resource vectors to identify a best-fit resource vector;
• routing said service request to a selected service host associated with said identified best-fit resource vector;
• monitoring processing of received service requests;
• identifying individual resource components in said service hosts which are consumed during said processing;
• and
• producing resource models for said service requests based upon said identified individual resource components in said service hosts;
• wherein said producing step comprises the step of computing a time series model for each of said service requests based upon said identified individual resource components.
