Abstract:
This paper introduces a P2P-based approach to sustain the high-availability ofWeb services using a similaritybased replication strategies. To this end three strategies known as active, passive, and hybrid, are studied. This approach takes replication one step further by focussing on Web services that offer the same functionality as the originalWeb service does (i.e., the one to back up). This functionality similarity is built upon communities that gather similarly-functional Web services. To prove the suitability of the selected replication strategy for Web services high-availability, a P2P testbed on top of the JXTA platform is developed.
