+## Apache Kafka
+
+[Apache Kafka](https://kafka.apache.org) is an open-source, distributed streaming platform designed for high-throughput, fault-tolerant, and scalable real-time data processing. It acts as a messaging system that enables applications to publish, subscribe to, store, and process streams of data (events or messages) efficiently.
+
+## Access the Kafka cluster
+
+The address to the boot strap servers in Oracle Backend for Microservices and AI is:
+
+`kafka-cluster-kafka-bootstrap.kafka.svc.cluster.local:9092`
+
+An example Spring Boot application.yaml could look like this:
+
+```yaml
+spring:
+  kafka:
+    bootstrap-servers: kafka-cluster-kafka-bootstrap.kafka.svc.cluster.local:9092
+```
+
+## Strimzi Operator
+
+The Kafka cluster is deployed using the [Strimzi](https://strimzi.io) operator. The cluster is using Zookeeper.
