Service selection based on status identification in SOA

Service Oriented Architecture (SOA) has become a new software development paradigm because it provides a flexible framework that can help to reduce development cost and time. SOA promises loosely coupled interoperable and composable services. Service selection in dynamic environment is the usage of techniques in selecting and providing quality of services (QoS) to consumers. The dynamic nature of web services is realized by an environment for collecting runtime information of web services. Based on the collected runtime information, several characteristics of service failures and successes are identified and four service statuses are defined. Based on these statuses, an approach to dynamic availability estimation is proposed along with multiple QoS criteria's such as cost and performance which is called Status Identification based service selection (SISS).
