The technology of splitting a monolith into independent microservices, which resulted in the development of a web application for a medical institution. It is shown that for “light” services it is worth using frameworks such as Micronaut or Express.js, and for “heavy” services it is worth using SOA architecture. Also, microservice architecture allows you to more clearly and visually localize/monitor “hot nodes” and thus develop recommendations. Kubernetes orchestration allows you to quickly manage the main processes that block secondary ones. A successful solution was the use of Security as a separate microservice. The created web application allows you to perform parallel processes by different authorized users without losing data processing speed. For example, for 100 simultaneous users, the response time of any operation in 99% of cases should not exceed 4 seconds when using MSA with standard server settings. The probability of an error does not exceed 0.1% of all cases.
