Reference Method for Load Balancing in Web Services with REST Topology Using Edge Route Tools

Abstract

AbstractDue to the great demand for information technologies, every organization currently offers products and services through web services, thus it is unquestionable that these must work uninterruptedly and stably. The strong implementation of web services with REST topology leads to developing distributed systems facilitating the scalability and portability of web services, but not in stability and performance. The objective of this research is to develop a reference method for load balancing in web services with REST topology using Edge Route tools. A reference method based on web services paradigms was developed and 3 REST APIs Laravel were tested with the information of 3 users randomly chosen at the request of a university tuition module, balancing the load with Treafik and escalating in Docker containers; a load of 7575 client requests was simulated using Apache JMeter and indicators of maximum response time and performance of the REST APIs were evaluated. Regarding the results of the application of the proposed method, the stability in maximum response time was improved up to 1.1 s from 2.2 s on average; likewise, there was a better performance in REST APIs with positive results when evaluating the proposed indicators; the greater the stability, the greater the scaling in containers. Having web services implies planning a broad architecture based on web services paradigms and load balancing to have better stability and performance.
