Event-Driven at Scale: Evolving Architectures with Kafka, Java, and AWS

What does it really take to scale event-driven architecture in a real-world platform? Inthis talk, we’ll share how XM, a global fintech company for online trading, evolved fromsimple 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 differentcombination of tools, from Spring Kafka and Kafka Streams to Flink, Lambdas, andKafka Connect. We’ll walk through what drove each choice, what paid off, whatbackfired, and how we wired everything together into something that actually runs inproduction.Expect a practical, experience-based look at building and operating event-drivensystems at scale. You’ll see real-world topologies, lessons we learned the hard way, andthe kind of tips we wish someone had told us earlier.
