Modernization of the backend of the web application based on microservice architecture

Abstract

The article considers the problem of inefficiency of web applications built on the basis of monolithic architecture, in particular in terms of speed, scalability and support. The relevance of the study is due to the increasing load on information systems and the need to ensure high performance when working with a large volume of user requests. The purpose of the work is to justify the feasibility of transitioning from a monolithic architecture of the backend of the web application to a microservice architecture and increasing the efficiency of the system through its structural decomposition. In the process of the study, an analysis of the existing architecture of the application was carried out, its logical and functional components were determined, which allowed for the decomposition of modules and the transition to separate independent services. The main functional microservices were identified , which are responsible for working with users, authorization, processing text, graphic and video data, working with vacancies and resumes, search engines, social networks, payment systems, mail and SMS services, as well as a security and administration module. The proposed architectural solution allowed to ensure independent scaling of individual services, simplify the process of their modernization and optimize the distribution of computing resources. The study contains a comparative analysis of the performance indicators of the web application before modernization and after the implementation of the microservice architecture. The results of testing the functions of administration, search and integration with social networks are presented, which indicate a significant improvement in the system response time. It is shown that the average increase in speed is from several times to several dozen times depending on the type of request. Special attention is paid to the optimization of the cluster infrastructure by redistributing resources and integrating specialized data storage and processing services. The results obtained confirm the effectiveness of using the microservice architecture to improve the server part of web applications and can be used in the development and modernization of complex information systems focused on high load, flexibility and stability of operation.
