S4 Applications Simulator for Performance Evaluation

摘要

Big Data is now a widely studied concept in the field of massive processing of information, but testing systems and applications in this field is a difficult task, because the real environments to be used are of a large scale and many times impossible to reproduce. Usually, for this task executions in virtual settings, called simulations, are used. The present article presents a simulator for applications developed to be executed on the Apache S4 distributed computing platform for multiple hardware and software scenarios. A version in which mobile devices as well as processing units are used is proposed. The results show that the simulator without mobile devices gets good prediction performance results considering the processing and communication times between the elements of the S4 applications, and the other version with mobile systems shows a decrease in performance in different simulation configurations. However, adding replication in the elements that are communicated with the cellphones has shown substantial improvements in the application's performance.
