In this talk, Beuzit will explain how Amadeus embraced EDA, and where they are in their journey. After a brief description of use cases, he will guide you through the steps of their progression: from discovery of Kafka / Kafka Streams to their first production implementation and the expansion of EDA across the company, sometimes relying on other technologies such as NATS.io. As part of this overview, Beuzit will give you a glimpse of some advanced patterns they implemented, an related challenges they presented. He will conclude by describing some challenges that await them in the months to come, with a special focus on their event mesh vision and why Solace PubSub+ is a promising approach for that.
