This section explains basic concepts about the object storage service.

Overview of the Object Storage Service

The Object Storage Service adopts the standard HTTP protocol and HTTPS protocol, which enables end users to locate and use their data with the Uniform Resource Identifier (URI). The object storage service abandons the directory tree structure and simplifies read/write semantics, facilitating massive data storage and management through Web.


Buckets are object containers and can be regarded as directories accessible from the network. Buckets cannot be nested, thereby avoiding complex multi-layer container structure.


Objects represent data and can be regarded as files accessible by the network. Objects are stored in a bucket.


Account is the credential to use object storage service. Accounts represent resource owners who can add, delete, query, or configure buckets as well as upload, download, or query objects.


Users are subject to, created by, and managed by accounts. The accounts grant permission to users to control their using of storage resources.

Figure 1-7 illustrates the relationship among buckets, objects, accounts, and users.
