Apache Kafka is a leading internet-scale streaming data platform, but many developers don't fully understand what a streaming data platform is. More importantly, organisations often don’t recognise how it could revolutionise their whole architecture. This session is aimed at those who want to learn more about how Apache Kafka represents a paradigm shift away from the data architectures of the past. It will explain the essential concepts behind Kafka (including its synergy with microservices-based development), demonstrate an example Kafka Streams application, and illustrate how such applications are composed together into a modern architecture.
