Event-Driven at Scale: Evolving Architectures with Kafka, Java, and AWS
Conference (INTERMEDIATE level)
Room 1
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.
