2. Configure bucket parameters.

   Table 1 Bucket parameters

   Parameter	Description
   Region	Geographic area where a bucket resides. For low network latency and quick resource access, select the nearest region. Once a bucket is created, the 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, you cannot change its name. An OBS bucket must be named according to the globally applied DNS naming rules as follows: A bucket name must be unique across all accounts and regions. A bucket name must contain 3 to 63 characters. Only lowercase letters, digits, hyphens (-), and periods (.) are allowed. A bucket name 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. A bucket name cannot be 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 features low access latency and high throughput. It is therefore suitable for storing a massive number of hot files (frequently accessed every month) or small files. The Warm storage class is ideal for storing data that is semi-frequently accessed (less than 12 times a year), with requirements for quick response. The Archive storage class is suitable for archiving data that is rarely-accessed (averagely once a year), without requirements for quick response. For details, see Storage Classes Overview.
   Bucket Policy	Controls read and write permissions for buckets. Private: Only users granted permissions by the ACL can access the bucket. 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 the default encryption is enabled for a bucket, all objects uploaded to the bucket are encrypted. The obs/default key is used for encryption 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 KMS encryption. If the default encryption is enabled for a 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.
