Coordinating service performance and application placement management

A method comprising coordinating performance management and application placement management, said step of coordinating comprising:

• estimating capacity needs for various service classes of service requests;
• computing desired capacities of at least one application for said service requests;
• deciding whether the desired capacities are satisfied by the current application placement;
• making no change to current application placement if the desired capacities are satisfied;
• determining a new application placement based on the desired capacities and a projected load if the desired capacities are not satisfied;
• computing corresponding capacity constraints for all pairs of service classes and servers;
• and
• computing an optimal allocation of capacities among the service classes so as to optimize the quality of service.

A method for provisioning at least one application to satisfy a quality service level for at least one service, said method comprising:

• coordinating a service performance manager and an application placement manager in a computer system, said service performance manager managing performance of said at least one service, and said application placement manager managing placement of at least one application, said application satisfying a service request for a particular service, the step of coordinating comprising the steps of:
• computing a desired capacity to achieve said quality of service level defined for said particular service;
• said application placement manager employing said desired capacity in determining a placement of said at least one application onto at least one server in said computer system in accordance with a placement policy;
• computing a capacity limit of said particular service to said at least one application based on said placement;
• and
• said performance manager determining an allocation of capacity to satisfy said quality of service level subject to said placement and capacity limit.

An apparatus to provision at least one application to satisfy at least one quality of service guarantee, said at least one application satisfying a plurality of service requests for a particular service, said apparatus comprising:

• means for computing a desired capacity to achieve said quality of service level defined for said particular service;
• means for employing said desired capacity in determining a placement of said at least one application onto at least one server in a computer system in accordance with a placement policy;
• means for computing a capacity limit of said particular service to said at least one application based on said placement;
• and
• means for determining an allocation of capacity to satisfy said quality of service level subject to said placement and capacity limit.
