Um estudo comparativo entre arquiteturas de software para aplicações Web

Abstract

CONTEXT: Software architecture is a concept related to element organization on a high level of the system, encompassing its structures and their communication. In the web applications development context, the tendencie is that their code become too much complex to maintain because of the lack of organization of the system. To develop easy to maintain and scalable softwares, it’s important that the application structure is well defined and architected. MOTIVATION: However, it’s possible to perceive that there are not recent studies about the software architectures usage, in a way of presenting definitions and comparisons between the architectures using practical examples. OBJECTIVE: Therefore, this study has the objective to present the main software architetures used in Web applications development, presenting its characteristics, advantages, disavantages and the main differences of its usage. The architectures addressed in this study are: monolith, client server, micro services, message oriented architecture and publisher subscriber. METHODOLOGY: To achieve this objective, this study will be divided in two parts. At the first one, there were done researches about the main software architectures used in Web application development, highlighting the usage context, advantages, disavantages and main difference of usage of each one with practical examples. The second stage, which is the main contribution of this study, will consist of research based on interviews with several experienced web developers. The main goal of this stage is to collect perceptions about the use of software architectures in web systems development. PRELIMINARY RESULTS: As preliminary results of this study, there were developed a simple Web application, implemented using all architectures mentioned separately, in order to obtain initial perceptions about their usages utilizing metrics of effort, performance and reliability. BENEFITS: The results of this study can facilitate the decision making of developers and help professors on the didatic material building about software architectures. Also, researchers can benefit themselves using the charcteristics of the architetcures discussed in this study.
