Über das Thema:
„Three years ago we started refactoring a monolithic shop into an e-commerce microservice platform. By now we’ve grown to
150 developers. In this talk we want to share our journey and the lessons we’ve learned the hard way.
After agreeing on a few terms about microservices we want to provide some answers to problems we ran into:
• What kind of organizational structure do you need to reflect the vertical boundaries in software while growing fast?
• 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?
• Can you enable your teams to develop and deploy independently all the way to production?
• How does asynchronous communication with Apache Kafka change the way you think about your entities?
• How can multiple microservices contribute to the same pages? (And why you might have to implement this twice...)
As you see we will share our interpretation of a micro service architecture where developers stay in the driver’s seat and have a
fair degree of independence and participation.“
