Análise de desempenho de middlewares para aplicações web

Abstract

Web services are the main middleware used in web application development, enabling communication between applications and easing the availability of services over the internet. SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) are ways of implementing web services that have become very popular in recent years, using standardized methods of communication, such as XML (Extensible Markup Language). This paper proposes a performance analysis of SOAP and REST middlewares on an e-commerce benchmark. A benchmark application was developed based on real systems, using Java language. The number of customer accesses was gradually increased. The performance of the middlewares was analyzed considering the usage of CPU, RAM memory, disk, network, and execution time of a request routine. This analysis identified the situations in which each middleware performs better, being able to guide the choice between SOAP and REST in future implementations.
