+# Prometheus Kafka Remote Writer
+
+![Architecture Diagram](./diagram.png)
+
+Prometheus Kafka remote writer is a remote writer/adapter to publish metrics from prometheus to a remote storage like kafka.
+The prom-kafka-writer microservice enables to register the remote endpoint and configures the kafka producer endpoint. 
+Prometheus can then be configured to set the remote write to this endpoint and the metrics can be published.
+
