What does it really take to scale event-driven architecture in a real-world platform? In

this talk, we’ll share how XM, a global fintech company for online trading, evolved from

simple service-to-service calls to a sprawling, event-driven ecosystem built on Kafka,

Java, Spring, and AWS.

As our systems (and headaches) grew, we tackled each new use case with a different

combination of tools, from Spring Kafka and Kafka Streams to Flink, Lambdas, and

Kafka Connect. We’ll walk through what drove each choice, what paid off, what

backfired, and how we wired everything together into something that actually runs in

production.

Expect a practical, experience-based look at building and operating event-driven

systems at scale. You’ll see real-world topologies, lessons we learned the hard way, and

the kind of tips we wish someone had told us earlier.
