Purchasing an AAD Instance (International Edition)

Before using AAD protection, you must purchase AAD instances.

  • After you purchase an AAD instance, refunds are not supported.
  • If an AAD instance has expired for more than 30 calendar days, AAD will stop forwarding service traffic and the instance will become invalid. If you do not need to use AAD anymore, switch your service traffic from AAD to the origin server 30 calendar days before the expiration date.

Prerequisites

Ensure that the account used for purchasing AAD instances has both the CAD Administrator and BSS Administrator roles or has the Tenant Administrator role.
  • BSS Administrator: has all permissions on account center, billing center, and resource center. It is a project-level role, which must be assigned in the same project.
  • Tenant Administrator: has all permissions on all services except on IAM.

Specifications Restrictions

  • Each user can purchase a maximum of five instances by default. If the quota is insufficient, submit a service ticket to apply for a higher quota.
  • If your service servers are located in Chinese Mainland, you are advised to purchase AAD. You have obtained an ICP license for your domain names to be protected by AAD.
  • If your service servers are located outside Chinese mainland, you are advised to purchase AAD (International Edition).
