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.
  • By default, Anti-DDoS Origin Basic is activated free of charge for Alibaba Cloud assets that are assigned public IP addresses. 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 assigned 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.
