   Table 1 Bucket parameters

   Parameter	Description
   Region	Geographic area where a bucket resides. For low latency and faster access, select the region nearest to you. Once the bucket is created, its region cannot be changed.
   Bucket Name	Name of the bucket. A bucket name must be unique across all accounts and regions. Once a bucket is created, its name cannot be changed. According to the globally applied DNS naming rules, an OBS bucket name: Must be unique across all accounts and regions. The name of a deleted bucket can be reused for another bucket or a parallel file system at least 30 minutes later after the deletion. Must be 3 to 63 characters long. Only lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot start or end with a period (.) or hyphen (-), and cannot contain two consecutive periods (..) or contain a period (.) and a hyphen (-) adjacent to each other. Cannot be formatted as an IP address. NOTE: When you access OBS through HTTPS using virtual hosted-style URLs, if the bucket name contains a period (.), the certificate verification will fail. To work around this issue, you are advised not to use periods (.) in bucket names.
   Storage Class	Storage classes of a bucket. Different storage classes meet different requirements for storage performance and costs. The Standard storage class is for storing a large number of hot files or small files that are frequently accessed (multiple times per month on average) and require quick retrieval. The Warm storage class is for storing data that is less frequently accessed (less than 12 times per year on average) and requires quick retrieval. The Cold storage class is for archiving data that is rarely accessed (once a year on average) and has no requirements for quick retrieval. For details, see Storage Classes Overview.
   Bucket Policy	Controls read and write permissions for buckets. Private: No access beyond the bucket ACL settings is granted. Public Read: Anyone can read objects in the bucket. Public Read and Write: Anyone can read, write, or delete objects in the bucket.
   Default Encryption	After default encryption is enabled for a bucket, all objects uploaded to the bucket are automatically encrypted. The obs/default key is used by default. You can also click Create KMS Key to create a key on the KMS console. Then select the created key on OBS Console for encryption. If the default encryption has been enabled for the bucket, uploaded objects are automatically encrypted.
   Tags	Optional. Tags are used to identify and classify buckets in OBS. Each tag is represented by a key-value pair. For more information, see Tag Overview.
