Overview

Anti-DDoS Origin Basic is activated by default. It provides a mitigation capacity of up to 5 Gbit/s for assets that belong to your Alibaba Cloud account free of charge. The assets include Elastic Compute Service (ECS) instances and Server Load Balancer (SLB) instances that are assigned public IP addresses. If the mitigation capacity of 5 Gbit/s does not meet your business requirements, we recommend that you purchase Anti-DDoS Origin Enterprise, Anti-DDoS Pro, or Anti-DDoS Premium instances to increase the mitigation capacity for your assets. For more information, see Billing methods of Anti-DDoS Origin, Billing methods of Anti-DDoS Pro, or Billing of Anti-DDoS Premium.

Assets that can be protected

You can use Anti-DDoS Origin to protect Elastic Compute Service (ECS) instances, Server Load Balancer (SLB) instances, elastic IP addresses (EIPs), EIPs that are associated with NAT gateways, simple application servers, Web Application Firewall (WAF) instances, and Virtual Private Cloud.
