Abstract

This paper presents an adaptive framework for managing dynamic replication of Web services in a distributed environment including the Service-Oriented Architecture (SOA) environment. The framework aims to improve the web services availability and to reduce the response time by supporting an automatic replication of the consumed web services according to environment changing conditions that might occur at the services provider side such as failure or increasing loading. For example, if one service or server fails, the framework replicates automatically the consumed service on another particular selected server based on some Service-Level Agreements (SLAs) including their performance and availability. Further, the framework balances the incoming requests using Round Robin a load-balancing algorithm. Moreover, the proposed framework is designed to predict the load of the involved candidate servers within the replication process through utilizing a statistical regression technique.
