    Storage Class

    OBS storage classes (Standard, Warm, and Cold) are designed to meet customers' varying requirements on storage performance and costs.

    • Standard: features low access latency and high throughput.
    • Warm: applicable to storing semi-frequently accessed (less than 12 times a year) data requiring quick response.
    • Cold: applicable to archiving rarely-accessed (once a year) data.

    For details about the storage classes, see Bucket Storage Classes Overview.

    Bucket Name

    Enter the bucket name, which must be globally unique.

    Name the bucket according to the globally applied DNS naming rule as follows:

    • Must contain 3 to 63 characters, starts with a digit or letter, and supports only lowercase letters, digits, hyphens (-), and periods (.)
    • Cannot be an IP address
    • Cannot start or end with a hyphen (-) or period (.)
    • Cannot contain two consecutive periods (.), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
