Avaliação de Desempenho para Sistemas Baseados em Container no Contexto de Indústria 4.0

Abstract

The need for scalable and flexible solutions has grown with the advent of Industry 4.0. In this scenario, software virtualization (containers) has been gaining ground by enabling rapid deployment in any environment. This technology is already present in large datacenters and, more recently, in embedded devices. The need to explore containerization in solutions that require a commitment to response time raises the following question: does the use of containers impact the performance and security of any adopted application or device?To address this question, scenarios were proposed to evaluate the impact of container adoption on a system by simulating various levels of workload in cyber-physical systems. The proposed tests were carried out on two distinct hardware platforms, both with computational resource constraints: one aimed at Internet of Things (IoT) applications and the other aimed at applications in industrial automation systems. From these analyses, it was possible to infer that the overhead introduced by adopting containers is similar to the system’s native performance. Although present, this impact does not significantly compromise the application.
