Product Advantages

  • 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.

  • 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.

  • 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.

Application Scenarios

General DNS Resolution

DNS enables you to map domain names to instances such as ECSs, OBS buckets, and load balancers.

Advantages

  • High Concurrency

    A single node can handle millions of concurrent queries.

  • Multiple Record Types

    You can add multiple types of record sets. 

  • Quick Operations

    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

  • Smooth Deployment

    You can easily deploy applications online and offline and seamlessly update offline changes to the online applications.

  • Easy Maintenance

    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

  • No Code Modification

    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. 

  • Free from DNS Spoofing

    You do not need to worry about DNS spoofing because private domain names are not exposed to the Internet.

  • Lower Latency

    A private DNS server directly responds to requests for private domain names, ensuring lower latency for your end users.
