In distributed systems, the hardest part is to guarantee reliable communication, that won't break due to some unsynchronized changes in collaborating services. During a live-coding session, we'll see how to ensure backward compatibility using deferred changes and contract testing. We'll as well see how can we use consumer-driven contracts to shorten the phase of the integration testing.
