Live Kafka cluster

Send a message through a
3-broker Kafka cluster.

This page talks to a real Apache Kafka 4.1.2 cluster running in KRaft mode on a Linux VPS, deployed entirely with Ansible. Your message is produced over a TLS + SASL/SCRAM listener, replicated across three brokers, then read back by a consumer.
