Design of highly concurrent course selection system based on microservice

At present, the main problem of college course selection system is that when facing a large number of requests in a short time, there will be server downtime. The high concurrency solution adopted by large-scale distributed systems will use a large number of server resources, which is not suitable for small and medium-sized web applications deployed on a single server. Therefore, it is necessary to propose an available high concurrency processing scheme for small and medium-sized web applications. This paper mainly uses micro service architecture combined with flow limiting technology to design a mainstream high concurrency scheme. This scheme can be applied to the course selection system to improve the efficiency of students' course selection. Using micro service architecture, the complex business functions are divided into several small service modules, which solves the challenges faced by the traditional system, so as to build an efficient, A stable course selection system.
