Abstract

In this paper, we focus on some design issues in distributed systems Middleware based on Web services,and their impact in future challenges. Middleware performance, Scalability, Management and Ubiquity are considered some of the
most elite challenges facing the designers of future middleware systems. Middleware performance can degrade at some point, the scalability of the distributed application can be difficult to control, managing large heterogeneous applications arises many questions, and finally, mobility and dynamic reconfiguration of applications forms the ubiquity challenge. As a guide for middleware designers, we propose this comparative study between different well known middleware systems considering our proposed design features as points of comparison, besides analyzing their impact on the previously
mentioned challenges.
