Resumo: |
One of the most relevant topics in computing today is the Service Oriented Computing. This paradigm involves, in general, the use of Web services for the implementation of business capabilities. Service oriented systems, promote the reuse and interoperability insofar as they are developed using widely diffused and accepted standards (mainly based on the HTTP protocol). In this context, two protocols have been used for the invocation of Web services: SOAP and REST. This paper proposes an approach, consisting of a methodology and a model to evaluate the performance of Web services. The methodology aims to detail the activities necessary for the achievement of a performance evaluation study specifically focused on services, while the model is intended to represent with an acceptable level of similarity, the actual system. Additionally, it was also proposed a case study comparing the measurement and simulation of results. In particular, considering that the two most important communication protocols, SOAP and REST have been proposed in recent years to support design for implementing Web services, the case study focuses on a comparative test of these protocols, in order to evaluate performance issues in real-world scenarios. In the measurement phase, an environment was created with two kinds of Web services installed on a server. But the simulation model was created based on the assessed scenario in the measurement phase. In all tests performed in this work show that the SOAP achieved a lower result compared to performance compared to REST in the study developed. |
