What is Ozone used for?

Ozone is a distributed storage system for data analytics and object store workloads, supporting S3 and Hadoop ecosystem integration. It is a good fit for build cost-effective, scalable data lakes for analytics workloads with tiered storage support; S3-compatible storage for applications, backups, and unstructured data at any scale; and reliable storage foundation for Hadoop, Spark, and other data processing frameworks.

Is Ozone open source?

Yes. Ozone is open source under the Apache-2.0 licence. Its source code is on GitHub at apache/ozone and is written mainly in Java.

Yes. Ozone is open source, so the software itself is free to use.

Can I self-host Ozone?

Yes. Ozone can be self-hosted on your own server or infrastructure.

What is Ozone an alternative to?

Ozone is an open-source alternative to Google Cloud Storage. Other open-source alternatives to Google Cloud Storage include SeaweedFS, RustFS and Ceph.

Is Ozone actively maintained?

Yes. The most recent commit to Ozone was on 14 October 2026. The project has 1.3k stars on GitHub.
