"This talk covers the ins and outs of choreographed microservice systems in depth, looking at everything from architecture and implementation details to design techniques.

Choreographed microservices talk to each other asynchronously, blindly broadcasting notifications into a service cloud. Those notifications are handled by whatever client services are interested. These systems eliminate many of the problems associated with orchestrated systems (which work more like synchronous function calls) and are typically much faster than orchestrated systems, but they have their own idiosyncrasies and implementation challenges. This practically-focused session explores the inherent problems in orchestrated systems, and then looks at how choreography can solve those problems. Three approaches to choreography: http-based, pub/sub messaging based, and brokerless swarming systems. We’ll introduce appropriate messaging architectures and frameworks and look at several practical examples. Finally, we'll look at Event Storming: one of the best approaches to designing choreographed systems. You'll come away from this session understanding both why you should be using choreography for most high-level APIs and how to design and build these systems.\"
