Object Storage Service Compatible with OpenStack Swift

The object storage service (compatible with OpenStack Swift APIs) has a distributed and scalable architecture and provides RESTful APIs. All the resources can be located by URLs. Data is organized in an account/container/object non-mesh structure. Massive data can be stored.


The object storage service is available only with an Account. As the owner and administrator of resources, an Account can add, delete, and query Containers, configure the attribute of Containers, and upload, download, and query Objects.

An Account can be regarded as a top-layer resource container or root directory that stores data.


Containers store Objects and are regarded as directories that can be accessed through the network. Containers cannot be nested, thereby avoiding complex multi-layer structure.


Objects represent data and are regarded as files that can be accessed through the network. An Object is always stored in a Container.

Figure 1-7 shows the relationship among Accounts, Containers, and Objects.
