99.99% SLA
50+ connectors
Runs on any cloud
Aiven for Kafka is the Kafka you know, re-engineered with a diskless architecture that slashes TCO by up to 80%. All while staying compatible with every client, every connector, and every tool you already use.
Run sub‑100 ms streams and up to 80% cheaper diskless topics in the same cluster. No silos, no cluster sprawl, just the same Kafka supporting different topic profiles inside the same cluster.
Leaderless architecture writes straight to S3/GCS, erasing cross‑AZ fees and disks. Scale storage and compute independently, and pay only for what you actually use.
Keep every client, connector, and tool. Just upgrade and go! It’s upstream-aligned, fully open source, and offers zero lock-in.

Powering mission-critical event streaming for top engineering teams
Why Aiven?
Our managed service makes it easy for you to build event-driven capabilities and applications, with predictable billing and backed by our 99.99% uptime SLA.
Infinite scalability with tiered storage
From real-time analytics to historical insights, build apps that handle it all. Aiven for Kafka scales compute and storage independently with tiered storage.
Built-in Schema Registry with Karapace
Ensure data integrity and prevent breaking changes with our open-source, Karapace-powered Schema Registry. It's fully integrated and managed for you.
Predictive consumer lag monitoring
Get ahead of bottlenecks. Our platform provides insights to help you identify consumer lag issues early, crucial for auto-scaling consumers and ensuring smooth data flow.
Automatic failure recovery
Self-healing clusters with automatic node recovery ensure your services stay online, and we run multi-node clusters across availability zones to guarantee our 99.99% uptime SLA.
Follower fetcher
Reduce network traffic, lower latency, and improve resource utilization by allowing consumers to read data from replica brokers instead of only the leader broker.

See how fast you can deploy a fully-managed Kafka cluster, produce your first message, and consume it in real time.
Apache Kafka® is an open source distributed real-time streaming product that powers event-driven architectures and high-performance data pipelines:
Easy integration: Kafka integrates with a long list of event sources and event sinks such as Postgres, JMS, Elasticsearch, and AWS S3
Aiven for Kafka is a managed version of the Apache 2.0-licensed open source Kafka. Aiven handles all the operational overhead of running a Kafka cluster, including server provisioning, patching, high-availability, backups, and security. Allowing you to focus on building your application, rather than on managing infrastructure.
Aiven has also made improvements to Kafka, such as through KIP-1150, which means Kafka can now write data directly to object storage, like AWS S3, using a leaderless architecture where any broker can handle any partition.
This eliminates expensive local disk replication for topic data, though brokers still leverage small amounts of disk for metadata.
The most common use cases are messaging, website activity tracking, operational monitoring, log aggregation, stream processing, event sourcing, and commit logging. These applications generally leverage more foundational or abstract use cases including:
Yes, we’ve taken great care to equip you with features that make it easier to develop applications with Kafka, including:
Data flow visualizer: Visually map your data flow across Aiven services and easily expand your pipelines.
Aiven offers standard Kafka security to connect using mTLS and/or SASL authentication with authorisation using ACLs.
Data at rest is always encrypted whether that be on disk or object storage.
There is also the option to enhance your security setup with Aiven's permission system offering a less cumbersome experience than ACLs.
We don't just run Kafka, we help build it. Our team includes dedicated Apache Kafka® open-source committers, ensuring deep expertise and a direct contribution to its evolution.
