Using ELB and CNAD Advanced to Improve the DDoS Protection Capabilities of ECSs Application Scenarios CNAD Advanced enhances the DDoS protection capabilities of cloud services, such as Elastic Cloud Server (ECS) and Elastic Load Balance (ELB), ensuring service security.

Cloud Native Anti-DDoS Advanced (CNAD) provides higher DDoS protection capability for cloud services on Huawei Cloud such as Elastic Cloud Server (ECS), Elastic Load Balance (ELB), Web Application Firewall (WAF), and Elastic IP (EIP).
Quick access to Cloud Native Anti-DDoS 2.0 Cloud Native Anti-DDoS 2.0 (CNAD 2.0) provides higher DDoS protection capability for cloud services on Huawei Cloud such as Elastic Cloud Server (ECS), Elastic Load Balance (ELB), Web Application Firewall (WAF), and Elastic IP (EIP).
Best Practices of Cloud Native Anti-DDoS (CNAD) Basic Accessing a Black-holed Server Through ECS
Accessing a Black-holed Server Through ECS Application Scenarios When your server is under a traffic flooding attack, a black hole will be triggered to block all accesses from the Internet. You can connect to a black-holed server through an Elastic Cloud Server (ECS).
After the attack ends, Huawei Cloud automatically removes the blackhole from the ECS and restores Internet access. When a server (ECS) enters is put in the blackhole, you handle it by referring to Table 1.
Routine maintenance Accessing a Black-holed Server Through ECS Use an ECS to remotely access the server that has been blackholed.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Once a dedicated EIP is associated with an ECS, it can be added to Unlimited Protection Advanced Edition and Cloud Native Anti-DDoS 2.0 for enhanced security. To purchase an Anti-DDoS Service dedicated EIP, perform the following steps: Procedure Log in to the management console.

It includes the following information: Traffic displays the traffic status of the selected ECS, including the incoming attack traffic and normal traffic. Packet Rate displays the packet rate of the selected ECS, including the attack packet rate and normal incoming packet rate.
After the attack ends, Huawei Cloud automatically removes the blackhole from the ECS and restores Internet access. When a server (ECS) enters is put in the blackhole, you handle it by referring to Table 1.
Related Services AAD can protect public IP addresses of services such as ECS, ELB, WAF, and EIP.
Figure 1 Typical causes Solution An ECS is used as an example. If the EIP of the ECS is exposed, you can reassign an unexposed EIP to the ECS to change the IP address of the origin server. Figure 2 Mechanism Procedure Log in to the management console.
HUAWEI CLOUD Anti-DDoS will trigger a black hole to block access from the Internet within a time period when detecting an ECS is under volumetric flood attacks.
CNAD Advanced protects Huawei Cloud resources, such as ECS, ELB, WAF, and EIP, by public IP addresses. Parent topic: Function Consulting
