SOA selection and replication based on QoS
Sutheera Puntheeranurak, Aekkawit Chanpen · 2014
Service Oriented Architecture (SOA) which contains a lot of consumers faces with reliability and availability problem. If one service fails, the user expects another alternative service to take the place of. In order to, increase service instance, service replication is adopted. To control the selection and replication of service, this paper proposes a service selection and replication based on Quality of Service (QoS). Service invocation will be even separated to each provider. While service replication will begin only if current service instances are not enough for number of consumers. Thus the system is able to control service replica properly and force service distribution for effecting regular consumer as few as possible.
