Coordinating service performance and application placement management

Abstract

Apparatus, systems and methods for service and/or business for coordinating tasks of performance management and application placement management in a dynamic fashion. An example process is dynamic in the face of fluctuations in the request load to the distributed computer system and the periodic adjustments to the placement of applications onto servers in said distributed computer system. There are two opposite functional flows in said process: a demand estimation function and a capacity adjustment function. The coordination system involves two subsystems: a demand estimator and a capacity adjuster, along with appropriate interfaces to of the performance manager and the application placement manager. This results in application placement process reacting quicker to demand fluctuations, performance guarantees are better met by rearranging the resources to be allocated to the various classes of service, and the management system works in an unsupervised mode, thus reducing manual administration costs and human errors.
