The Practical Road towards CQRS and Event Sourcing

3 May 16:00 - 16:50 Room C4


The terms ‘Command Query Responsibility Separation (CQRS)’ and ‘Event Sourcing (ES)’ pop up often these days. But have you already tried building such a system yourself? The concepts by themselves are quite straightforward.

However, building the infrastructural component you need for CQRS and ES from scratch is challenging. And a waste of your valuable time. Axon provides numerous building blocks to support developers on their journey towards a CQRS and ES-based application and has been used in production for over a decade. In this session, we will live-code an application from scratch. You will see how to apply CQRS and ES to your application.

We will also discuss how "location transparency" helps keep your architecture flexible, giving you the power to evolve your architecture as the need arises.
