Web services requests are larger than requests encoded with binary protocol. The extra size is really an issue in either low speed connections or extremely busy connections. Traditional Byzantine Fault Tolerance (BFT) replication mechanism can be used to mitigate the threats to the Web Service-Business Activities (WS-BA) coordination service. The present lightweight BFT algorithms mitigate the threats and avoid the runtime overhead associated with traditional BFT algorithm. Some of the problem found in present system is less security, low performance and less data availability.
