Everyone knows how to build a monolith application. But nowadays trends and technologies require other approaches and other skills. People today strive to build distributed applications. It's not easy! In this discussion I will present a simple and practical introduction to a few patterns that will help you to build your next distributed application. We will start from a short journey to the history of classic monolithic applications. After that we will see the gradual evolution from those monolithic architectures to the real distributed event-driven applications. I'll provide you with the tools and knowledge you need to start designing and developing your next distributed application.
