[Demo+Webinar] New Product Updates to Make Serverless Flink a Developer’s Best Friend | Watch Now

A Complete Comparison of Apache Kafka vs Confluent

Used by over 70% of the Fortune 500, Apache Kafka has become the foundational platform for streaming data, but self-supporting the open source project puts you in the business of managing low-level data infrastructure. With Kafka at its core, Confluent offers complete, fully managed, cloud-native data streaming that's available everywhere your data and applications reside.

Here are the major differences between Confluent and Kafka, as well as a complete stackup of features - from connectors, security, and monitoring, to governance.

To truly tap into Kafka, you need Confluent

Cloud-native

Eliminate your ops burden with a truly cloud-native Kafka solution

While Kafka is a powerful distributed system, modern enterprises do not want to be in the business of supporting the open source distribution in-house. ZooKeeper needs to be managed, partitions rebalanced, failover and scaling processes designed — the list goes on. Confluent completely re-architected Kafka from the ground up to provide teams with a truly cloud-native experience that delivers an elastically scalable and globally available service ready to deploy, operate, and scale in a matter of minutes.

Complete

Accelerate time-to-value and reduce TCO with a complete data streaming platform

Kafka is a powerful platform, but it doesn’t offer everything you need out-of-the-box. With open source Kafka alone, you’re on the hook to build and maintain foundational tooling and infrastructure, such as connectors, data governance and security, disaster recovery capabilities, and more. And when ready to deploy, the platform creates a significant ongoing operational burden — one that only grows over time. Your business has better things to do. Confluent provides a holistic set of enterprise-grade capabilities designed to eliminate the need to spend costly dev cycles building and maintaining tools, helping customers save up to 60% in TCO and quickly realize value from their real-time use cases.

Everywhere

Seamlessly connect your data and applications everywhere they reside across hybrid and multicloud architectures

Kafka helps to streamline digital architectures in real time, avoid complex point-to-point integrations, and break data silos. To truly meet that goal though, you need a solution that spans all of your environments, both on-premises and across cloud providers. Confluent exists everywhere your applications and data reside, providing you the freedom to leverage a fully managed service on all leading public clouds and self-managed software you can deploy for on-premises workloads, whether on bare metal, VMs, or Kubernetes. Best of all, you can seamlessly connect it all together in real time with Cluster Linking to create a consistent data layer across your entire business.

"For me to go hire a bunch of engineers to babysit Kafka, I don’t have the ability to go do that. And being able to offload those concerns is just such a relief for us and lets us focus on delivering value to the organization and not worrying about ops and other overhead... Just things like spinning up Kafka clusters and getting prototypes up and running very quickly, Confluent has been really helpful there. Those sort of exercises might take a long time for my team to do if we were doing this on vanilla open source Kafka. With Confluent, we can turn that around very quickly."
