Dynamic Service Composition in SOA and QoS Related Issues

Service Oriented Architecture (SOA) is a modern approach to build distributed application and greatly reduce the time, effort and cost to develop the software projects. SOA provides the dynamic paradigm for composing distributed application even in heterogeneous environments. The dynamic composition feature in SOA makes evaluation of a QoS a major challenge. The goal of our paper is to study approaches that enable the management and evaluation of QoS for efficient dynamic service selection and composition.
