J-Fall 2018: Ansgar Brauner & Sebastian Gauder – A competitive food retail architecture with microservices

Three years ago we started refactoring a monolith into a microservice platform. We want to share the lessons we’ve learned the hard way and provide some answers to problems we ran into:

  • What kind of organization helps to reflect the vertical boundaries in software while your team grows?
  • How do you define bounded contexts with many teams and features?
  • Are there ways to guide your teams and enable autonomy on all levels in your organization?
  • How does Eventing change the way you think about your entities?
  • How can multiple microservices contribute to the same pages?

As you see we will share our interpretation of an architecture where developers stay in the driver’s seat and have a fair degree of independence.
