Apache Kafka®
Now running 4.1
Cloud Kafka just got (a lot) better.
Scale storage and compute independently with Diskless Kafka, and pay only for what you actually use. It’s Kafka, reimagined.
99.99% SLA
50+ connectors
Runs on any cloud
Aiven’s Diskless Kafka is the Kafka you know, re-engineered with a diskless architecture that slashes TCO by up to 80% — while staying compatible with every client, every connector, and every tool you already use.
Run sub‑100 ms streams and 80% cheaper batch topics in the same cluster — no silos, no cluster sprawl, just one cloud‑native engine for every workload.
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. Kafka, reimagined.

Bring your own cloud (BYOC) deployed as stateless service, directly in your VPC with no disks to manage.
Aiven’s Diskless Kafka writes 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.
Apache Kafka stores and replicates data across multiple broker servers using local disks, with a designated leader broker handling writes to each partition while follower brokers maintain copies.
This architecture requires cross-zone disk replication for high availability, which generates expensive network traffic as data is duplicated across different cloud availability zones.

Frequently asked questions
Apache Kafka® is an open source distributed real-time streaming product that powers event-driven architectures and high-performance data pipelines:
- Proven performance: Kafka is trusted by a large proportion of the world’s largest and most demanding companies, across practically every major sector.
- Valuable versatility: From its origins as a real-time user activity pipeline, Kafka has grown into a key enabler of messaging, metrics, log aggregation, stream processing, event sourcing — and more.
Easy integration: Kafka integrates with a long list of event sources and event sinks — including 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.
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:
- Streaming directly into data lake: Stream data directly into Iceberg tables and query it instantly, bringing database-like functionality to your data lake.
- Event-driven microservices: Decouple your services and enable resilient, scalable communication. Use Kafka as the central nervous system for your microservices architecture, allowing teams to build and deploy independently.
- Log & metrics aggregation: Create a unified, scalable observability pipeline. Ship logs and metrics from all your systems into a central Kafka cluster, then sink them into Aiven for OpenSearch® for powerful search, analysis, and visualization.
- Change Data Capture (CDC): Stream every INSERT, UPDATE, and DELETE from your operational databases like PostgreSQL and MySQL into Kafka topics using our managed Debezium connector. Unlock the value of your operational data without impacting source systems.
Yes, we’ve taken great care to equip you with features that make it easier to develop applications with Kafka, including:
- Streamlined topic ownership: Enable application teams to request and own their Kafka topics directly, with built-in approval workflows that ensure governance without bottlenecks.
- Topic catalog for discovery: Our comprehensive topic catalog makes it easy for teams across your organization to discover and reuse existing data streams, preventing duplication and increasing data reuse.
- Quality-first data streams, every time: Our integrated Schema Registry automatically enforces data quality and consistency, preventing breaking changes and simplifying data evolution.
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.
