Analysis of selected features of application based on monolithic and microservice architecture

The article describes the performance of applications built in monolithic and microservice architectures. The base of research includes application supporting prescription management developed with the use of Spring Framework technology and implemented in the Docker Swarm test environment. The tested applications were subjected to various loads in the form of sending HTTP requests that simulated user behaviour. The research has proven that an application created based on microservices architecture offers better traffic handling in case of high load. Scaling a microservice application allows for greater gains in performance measured as quantity served client requests per unit of time than scaling a monolithic application under the same conditions scaling
