You were assigned to refactor your existing monolith, legacy system, or other to-be-deprecated code into a shiny new event-driven system. And let us assume that you want to use the Spring Boot and Spring Cloud Stream as your guiding architectural choices while you are in the process. These are not just cool things to use. They are robust tools for building modern microservice-based apps!
In this talk, Viktor Gamov live-code his way to a small, functioning Spring Boot microservice. Apache Kafka integrates the services, and Spring Kafka and Spring Cloud Streams as the API of choice. You will see how to use Spring and Kafka together, apply the opinionated design patterns, and avoid the antipatterns while building event-driven architectures and real-time stream processing systems. As a bonus, we will ship this microservice to production in Kubernetes using Spring Boot tools!
