Storage > Object Storage > Overview

Object Storage is an online storage service that can store large-capacity data.



Capacity can be expanded almost infinitely. Users can store as much data as they want when they need it, without worrying about storage capacity.

Control Accessibility

Access permissions can be set per container. Containers set to private can only be accessed by authorized users. When a container is set to public, anyone can access the objects inside the container using a public URL.

Ensure Data Reliability

To store data safely, a total of 3 copies of each object are created. While creating the copies, the integrity of the replicated data cannot be guaranteed and therefore the data is inaccessible. So, if you send a GET request immediately after storing data, you might get a failure response. If at least two copies are identical, the replication is considered successful, and the storing is completed and the data becomes accessible.

Provide a Convenient Web Console

For user convenience, a web console is provided to manage data in a hierarchical directory structure. When an application accesses data, the RESTful API can be used with the object ID. When a user directly accesses data, they can use a web console with a familiar directory structure. You can manage objects by grouping them using folders.

Provide RESTful API

HTTP(s)-based REST API is provided to control containers and objects. The API allows you to use object storage in your applications.



The basic management unit of object storage, which refers to the data to be stored. Generally a file is used as an object.


A virtual unit that binds multiple objects. It helps to manage objects hierarchically, similar to folders in Windows or directories in Linux.


Refers to the top-level folder. Basically, a container becomes the unit of access permission setting. All objects must exist in a container.

Storage Account

A user account for object storage. NHN Cloud Object Storage is isolated on a per-account basis.

API Endpoint

HTTP URL provided to access object storage with REST API. You can access object storage by making a request with the URL.
