Chapter 1. Overview of AMQ Streams

AMQ Streams is based on Apache Kafka, a popular platform for streaming data delivery and processing. AMQ Streams makes it easy to run Apache Kafka on OpenShift.

AMQ Streams provides three operators:

Cluster Operator
Responsible for deploying and managing Apache Kafka clusters within an OpenShift cluster.
Topic Operator
Responsible for managing Kafka topics within a Kafka cluster running within an OpenShift cluster.
User Operator
Responsible for managing Kafka users within a Kafka cluster running within an OpenShift cluster.
