Software architecture is considered one of the most important indices of software engineering today. Software Architecture is a technical description of a system indicating its component structures and their relationships, and is the principles and rules governing designing. The success of the software depends on whether the system can satisfy the quality attributes. One of the most critical as...

When developing large software systems it is hard to predict their performance behavior at early development stages. This paper presents an engineering methodology for performance prediction based on high-level application architectures that are simulated within the real infrastructure setup. This methodology is realized in a performance simulation framework. Our results show that a software sy...

∗ Work partially supported by funds from the FIRB project “Performance Evaluation of Complex Systems: Techniques Methodologies and Tools” and by the University of Rome TorVergata CERTIA Research Center. Abstract — Distributed simulators are increasingly being used for their intrinsic advantages in terms of reusability, fault tolerance, performance, and geographic distribution. The development o...
