How to drive an Event-driven Architecture for microservices

Event-driven Architecture logoAn Event-driven architecture (EDA) could be a candidate to realize a communication-basis between microservices and an approach to get the services mostly decoupled. The architectural pattern exist for a couple of years and has been described in papers and articles like [1,2,3].
However in this and the following post I won’t repeat the theory in detail, I’d rather like to describe how to sketch an EDA based system and just sometimes use quotations of the papers above – like [1]:

An event is a notable thing that happens inside or outside your business.


Prototype sketching with Apache Camel

Almost every new project contains legacy code, legacy components or systems. Besides the business-logic a lot of boilerplate code has to be created; only to realize the integration of the legacy parts. Additionally at the beginning of a project it is not clear if the chosen approach works to integrate the legacy components. Coding different scenarios to integrate several technologies is not done within a few hours, more likely in a couple of days. I.e an architecture or integration prototype would be helpful to verify the ideas and figuring out possible issues and challenges up front. Weiterlesen
