A dynamic aware-feedback system for service replica management

Cloud service provides a new model of distributed computing. The virtualization technology makes it easy to manage the computing unit, the service, as a data file block. So the optimization to a data network, such as P2P, CDN, etc. can be reused in service network. However, since software service is not a static data file but dynamic running instruction set, there will be a lot more factors to be taken into account than pure data circumstance. This paper discusses the technology of service network optimization, and proposes a new method and system of service replica management to improve the service oriented distributed software performance.
