Confluent 17,245 , founded in 2014 by the engineers who created Kafka 129 at LinkedIn, sells the managed Kafka service with the most built-in extras: clusters run on Kora, its cloud-native Kafka engine, on AWS 24 , Google Cloud 1 and Azure 6 , with Schema Registry, connectors, Flink 129 and governance in the same console and on the same bill. Confluent Cloud 17,245 was not run here: the book creates no accounts with paid services. The limits, prices and trial terms below come from Confluent's pricing page and documentation on 2 October 2026, in US dollars at the base regional rate (regions with a multiplier cost more), and they change often.
