What each one is

The product in its own terms, so the numbers below have context.

Apache Kafka

Apache Kafka is a free system for capturing, storing, and processing data streams in real time. It enables organizations to reliably move large volumes of data between applications and systems, with support for transformations, aggregations, and stateful processing.

Independently observed

Confluent Cloud

Leader

Confluent Cloud is a fully managed Apache Kafka service enabling organizations to stream high-volume, low-latency events between systems in real-time. It eliminates operational overhead through automatic scaling, multi-region replication, and costs significantly less than self-managed Kafka deployments.
