FAULT TOLERANT SYSTEM IN WEB SERVICES

Abstract

The web technology has been increasingly used for critical applications and services. However quality of services (QoS) must remain in priority. Qualities such as high availability, performance, reliability and security have been an issue. Aiming to solve this limitation, this research will proposed an architecture providing dependability for web services in an e-commerce. The architecture is designed using NCAPS mechanism which apply replication and redundancy components mechanism for server side execution. All the components involved will be a renew version of previous work done. Firstly the client server physical design is proposed and then the detailed component in the structure of server is suggested. The discussion is divided into several side which includes network, middleware, duplex manager, and linking. Then the strength and weakness of the proposed architecture is outlined.
