Deployment of a web application with Nginx on VPS: performance analysis in a digital medical records system

Abstract

The purpose of this study is to document and analyze the deployment of a web application for psychological medical records implemented with Nginx on a virtual private server (VPS), developed as part of the Software Engineering Project course and applied in a real environment. The methodology adopted corresponds to a descriptive study of an applied nature, in which a production environment based on decoupled client-server architecture was configured and its performance was evaluated using load tests with Apache JMeter, considering metrics such as response time, median, standard deviation, and throughput. The results showed stable response times close to 217 ms, no errors during the execution of 1000 concurrent requests, and consistent server behavior under moderate load. It is concluded that the Nginx-based configuration on VPS is a viable and controllable alternative for applied academic projects that require transferring solutions developed in the classroom to real production environments, maintaining adequate stability and performance for small and medium-scale clinical management applications.
