  • Metadata-Support: Each object is identified by an unique key and metadata can be used for more organizational control.
  • S3 compatible API: supports S3 compatible APIs so that you can rely on huge number of existing tools. Please refer to Tools.

The Contabo Object Storage is based on Ceph. It is not fully compatible with AWS S3 API. E.g. logging is not supported. For the very most use cases you shouldn't notice any difference.
