A Framework for Performance Analysis of Client/Server Based SOA and P2P SOA

An analytical framework is developed to derive the response time and service availability of client/server based SOA and P2P based SOA. The impact on the response time and service availability for varying load conditions and connectivity for both client/server and P2P SOA implementation is studied. It is found that the response time reduces significantly in P2P based SOA depending on network connectivity and service replication factors. Service availability is also found to be much higher in case of P2P based SOA and the gain are enhanced for higher values of load. In our analysis the impacts of search latency and bandwidth penalty resulting from UDDI distribution are not yet considered.
