    The COS console is the easiest way to work with COS without using any code or programs.


    If this is your first time using COS, you are advised to learn the following concepts first.

    • Bucket: A container for objects stored in COS. Each bucket can store an unlimited number of objects.
    • Object: The basic unit of COS storage. It can be data in any format, such as images, documents, audio and video, and others.
    • Region: A physical location where data centers are hosted on Tencent Cloud. COS data is stored in the buckets in these regions.
