A Self Analysing and Reliable SOA Model

Service Oriented Architecture (SOA) provides a new way of application development by using existing services. The required services are collected and loosely composed to meet the user’s specification, where the architecture of SOA is dynamic that is, it can change dynamically at run time to meet the new requirements. This paper proposes an architecture which has the capability to analyze the developed services by comparing the user’s requirements. Finding a method for testing the accuracy of a service is a challenge always. The architecture provides a unified way of self analysis which evaluates the perfectness of developed service, before its delivery, and to find out its accuracy. This calculated perfectness is stored in the service profile of that service. The database is maintained for each service which helps for searching a required service to meet user’s specification and for composition of a new service. When this self analysis of the developed service does not satisfy to meet the user’s requirement because of not satisfying any conditions, it generates the fault. Fault is handled to provide the required correctness for composition of the service by detecting the services responsible for those faults. The architecture provides both reliability and analysis capability by handling fault and by searching a service based on accuracy which provides reliable delivery of service.
