Flexible Routing
DNS routes traffic based on multiple criteria, including endpoint health and geographic region. You can configure traffic routing to resolve specific end user requests.DNS routes traffic based on multiple criteria, including endpoint health and geographic region.

High Performance
A single DNS node can handle millions of concurrent queries. Huawei's global infrastructure allows your end users to quickly access the closest application endpoints that are healthy, minimizing latency.A single DNS node can handle millions of concurrent queries.

Easy-of-Use
You can easily configure DNS records using the console or APIs. DNS immediately handles queries once you create a zone and add record sets to it.You can easily configure DNS records using the console or APIs. DNS immediately handles queries once you create a zone and add record sets to it. -
Robust Security
DNS offers built-in DDoS mitigation and works with Anti-DDoS to ensure that requests from your legitimate end users are not affected.DNS offers built-in DDoS mitigation and works with Anti-DDoS to ensure that requests from your legitimate end users are not affected.

General DNS Resolution
DNS enables you to map domain names to instances such as ECSs, OBS buckets, and load balancers.
Advantages
A single node can handle millions of concurrent queries.
You can add multiple types of record sets.
You can import up to 500 record sets on the DNS console. The record sets you add are effective within a minute.
Service Management
You can create public and private zones for the same domain name and deploy your applications online and offline.
Advantages
You can easily deploy applications online and offline and seamlessly update offline changes to the online applications.
You can test offline applications in a VPC without interrupting online applications.
Application Deployment
You can map private IP addresses of servers to private domain names in specific VPCs, thereby allowing the servers to communicate by using domain names.
Advantages
If a server becomes faulty, you only need to change its IP address in the DNS record set. You do not need to change the code.
You do not need to worry about DNS spoofing because private domain names are not exposed to the Internet.
A private DNS server directly responds to requests for private domain names, ensuring lower latency for your end users.
