In this work the concepts of relatively new, microservice architecture are explored. Due to the great technological difference and progress of the last ten years, the industry has developed the concept of a new way of application development in an effort to fulfill the wishes of users as well as possible, namely a microservice architecture that enables faster delivery, more stable system, easier testing and upgrades. Microservices are not standardized and do not have their own strict rules, but it is clear that in this architecture the application is divided into smaller parts that can be independently run, tested and upgraded. Although this style offers the advantages already mentioned, some of the disadvantages of this style are the complexity of integrating many small parts, difficult to understand the whole system as it can be written in different technologies, and this makes system maintenance difficult, the need for a special component and data transmission network. Some of the challenges of this architecture can be easily solved by using already existing solutions in the implementation of which the Kubernetes and Spring Cloud platforms currently stand out. They offer solutions for system configuration, microservice detection, microservices load balancing, system-wide metric tracking, and advanced fault tolerance solutions. On the example of a developed application for reports in the context of e-business based on microservice architecture, good practices and concepts of this style of development are shown. The application consists of four microservices, and different programming languages and development frameworks were used. Special attention is paid to the possibility of scaling the application and future upgrades.
