This topic describes how to purchase an Anti-DDoS Origin Enterprise instance.

Background information

Anti-DDoS Origin is offered in two editions: Anti-DDoS Origin Basic and Anti-DDoS Origin Enterprise. Take note of the following items:
  • By default, Anti-DDoS Origin Basic is activated for Alibaba Cloud assets that have public IP addresses free of charge. Anti-DDoS Origin Basic provides a basic protection capacity of up to 5 Gbit/s against DDoS attacks.
  • Anti-DDoS Origin Enterprise is a paid service that protects Alibaba Cloud assets that have public IP addresses. Anti-DDoS Origin Enterprise provides shared and best effort protection capacities. You do not need to change your service IP address.

    Best effort protection defends against DDoS attacks based on the overall network capacity of Alibaba Cloud. The best effort protection capacity increases with the increase of the overall network capacity of Alibaba Cloud. You do not need to pay extra fees for the increase in capacity.

    For more information about the billing methods of Anti-DDoS Origin, see Billing methods of Anti-DDoS Origin.

    Note If you want to protect elastic IP addresses (EIPs), you can go to the EIP buy page and select Anti-DDoS (Enhanced) for Security Protection. For more information, see Apply for an EIP. For more information about the billing information of the Anti-DDoS (Enhanced) feature, see Pay-as-you-go.
