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

Prerequisites

  • The enterprise real-name verification is completed for your Alibaba Cloud account.

    You can purchase an Anti-DDoS Origin Enterprise instance only after you complete enterprise real-name verification.

  • The cloud assets that you want to protect are public IP addresses of Elastic Compute Service (ECS) instances, public IP addresses of Server Load Balancer (SLB) instances, elastic IP addresses (EIPs), or IP addresses of Web Application Firewall (WAF) instances.

Background information

Anti-DDoS Origin is offered in two editions: Anti-DDoS Origin Basic and Anti-DDoS Origin Enterprise.
  • Anti-DDoS Origin Basic is activated by default. Anti-DDoS Origin Basic provides a basic protection capacity of up to 5 Gbit/s against DDoS attacks free of charge for public IP addresses of Alibaba Cloud resources.
  • Anti-DDoS Origin Enterprise must be purchased. Anti-DDoS Origin Enterprise protects public IP addresses of Alibaba Cloud resources, including ECS instances, SLB instances, EIPs, and WAF instances. Anti-DDoS Origin Enterprise provides shared and unlimited protection capacities. You do not need to change your service IP address. Unlimited protection defends against DDoS attacks based on the total network capacity of Alibaba Cloud. The unlimited protection capacity increases with the increase of the overall network capacity of Alibaba Cloud. You do not need to pay extra fees.
