RESUMO
SOA is becoming a widespread approach to develop systems. High demand problems may appear in huge systems where SOA and web services are used. This problems can be solved by means of distributed architectures like clusters. This work presents the proposal of a new architecture for request distribution in web service clusters. The proposed architecture provides flexible request distribution. It allows the use of several policies, these related to different objectives, applications and platforms. The architectures dynamic feature enables decisions based on states of the clusters elements, in a transparent way, under clientspoint of view. The architecture was tested using a prototype that implements the proposed ideas in this work. The objectives of the proposal were reached by the prototype and still shown performance improving in many cases, when comparing to an existing solution. The use of a novel policy, related to energetic efficiency for clusters, is also shown on the experiments related to flexibility. Among architectures contributions is a novel software architecture that acts as a facility to create and to test more efficient web services policies
