Abstract <p>The prospects for using microservice architecture in the development of flexible automated production control systems at mechanical engineering enterprises are considered. Methods for designing and implementing automated production control systems based on microservice architecture are discussed, and the advantages and disadvantages of this approach are shown. A prototype of a flexible automated system, developed using the Java language and the Spring framework, was proposed for the butt welding section of a metal disc production plant. The developed concept is a set of software modules in the form of microservices for independent data processing at each stage of the production process, which increases the fault tolerance and reliability of the entire system.</p>
