📄️ Storage Container Manager

Storage Container Manager (SCM) is the leader node of the block space management.

📄️ Ozone S3 Gateway

Apache Ozone’s S3 Gateway (often called S3G) is a component that provides an Amazon S3-compatible REST interface for Ozone’s object store.

📄️ Datanodes

Datanodes are the worker bees of Ozone. All data is stored on data nodes. Clients write data in terms of blocks.

Recon serves as a management and monitoring console for Ozone. It gives a bird's-eye view of Ozone and helps users troubleshoot any issues by presenting the current state of the cluster through REST based APIs and rich web UI.
