Through this thesis we have studied and described the whole process of application development using microservice architecture. We highlighted the advantages of using this architecture over monolithic, especially from the aspect of application scaling. Although the monolithic approach is faster, it has a number of limitations when scaling which could cause some problem in the future. The ability to scale is a very important factor when developing web applications. At all times, we want to provide users with the best possible experience when interacting with our system, and monitoring a large number of microservices without tools like Kubernetes would be an extremely difficult and even impossible task. In this paper, we have demonstrated the advantages of the Kubenetes system, which allows us to manage a large number of different microservices. We have submitted a description of the service in the form of YAML files to the Kubernetes system, and Kubernetes itself takes care that the cluster always matches the description. In the event of a service failure, Kubernetes will restart it and switch to another work node if necessary. Also, Kubernetes is able to scale the entire application itself. It constantly monitors the load of our services and in case of increased traffic can independently launch a new copy of a particular service. Everything happens automatically. This way, we don’t have to worry that a sudden increase in traffic will crash the entire app.
