Avaliação arquitetural do Sistema SUAP: uma análise sistematizada sobre desempenho

Abstract

Information systems have become increasingly robust, working with high data volumes, objects and processes. In the context of the Federal Institute of Rio Grande do Norte (IFRN), a system was developed to attend all the administrative and academic activities of the institution: the SUAP, Unified System of Public Administration. Over the course of 11 years, the application has evolved from just one module to over 40, in addition to the dizzying growth of users – which today permeates the number of 35 thousand. These aspects often impact directly and negatively on systems performance, leading software architects to seek alternatives to scale better their applications. In the case of the IFRN, even after high investments in infrastructure, SUAP performance problems persist. In order to make better use of the available hardware structure, it is necessary to understand the reasons for these performance problems, so that these computational resources are used dynamically and incrementally, managed more efficiently and able to withstand surplus loads without prejudice to application performance. Thus, the need to evaluate more comprehensive aspects of the current architecture of the application is presented, so that elements that impair it’s performance can be known. This work aims to perform a systemized SUAP’s performance analysis through the application of the Architecture Trade-off Analysis Method (ATAM) and the execution of a set of performance tests that allow the identification of it’s main points of slowness. With this, it is hoped to contribute to the definition of a strategy for performance tests that can be incorporated into the SUAP’s development process.
