About S3 Clusters
-----------------

.. include:: /includes/about-s3-clusters-part1.inc

The infrastructure of the object storage consists of the following entities: object servers (OS), name servers (NS), and the S3 gateways (GW).

These entities run as services on the |product_name| nodes. Each service should be deployed on multiple |product_name| nodes for high availability.

This section shows a sample object storage deployed on top of an storage cluster of five nodes that run various services. The final setup is shown on the figure below.
