Microservices with Java

Microservices are an architectural style that promises many benefits, but also comes with challenges. The implementation can be based on various Java Open Source frameworks. The programming language, communication log, persistence solution and the libraries used can vary for each Microservice. You can therefore choose the most effective tools for a specific problem. In the Spring Boot, Dropwizard and WildFly Swarm examples, we implement different, decoupled services in this seminar, which communicate with each other through lightweight protocols. Here, we consider typical aspects such as centralized configuration options, service registration/discovery, monitoring/health checks and resistance to failure. At the end of the seminar, you will have a good overview of the most well-known models and their respective characteristics and effects. You could also try out the typical elements of a Microservice architecture directly on concrete examples.
