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.
- A purchase request is submitted on the Application for Anti-DDoS Origin page.
You must submit your company information so that Alibaba Cloud can determine your business needs.
- The cloud assets that you want to protect include public IP addresses of ECS instances, public IP addresses of SLB instances, elastic IP addresses (EIPs), or IP addresses of WAF instances.
Background information
- Anti-DDoS Origin Basic is enabled by default. It provides a basic protection capacity of up to 5 Gbit/s against DDoS attacks for public IP addresses of Alibaba Cloud resources free of charge.
- Anti-DDoS Origin Enterprise must be purchased. It 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.
