A payments company runs a self-managed Apache Kafka cluster in its data centre, carrying card-authorisation events between thirty microservices. Every service uses Kafka client libraries and relies on Kafka features such as consumer groups, partitions keyed by card number and replaying a topic from an offset. The company is moving to AWS and wants to stop patching brokers and managing ZooKeeper, without changing any producer or consumer code. The consuming services run as containers, and every event must also be archived to cheap storage for seven years of dispute handling, without writing custom archiving code.
