Domain Name Service (DNS)

Domain Name Service (DNS) provides high-availability, scalable authoritative domain name resolution and management services. It translates domain names into IP addresses required for network connections to route end users to the desired applications.

Global Deployment

Route end users to your application at a low latency with DNS services deployed in more than 20 countries or regions.

Fast DNS Queries

Accelerate access to your application with Huawei's in-house next-generation DPDK.

Robust Security

Add security to your application by leveraging terabyte-level protection capacity provided by Anti-DDoS Service and more than 10 years of experience with attack defense.

100% Availability

DNS is independently developed by Huawei Cloud. Provide high-performance authoritative services for your end users so that they can have reliable access to your application.

Why Huawei Cloud DNS?

Route Traffic Globally

Get faster responses to DNS queries and enable end users to securely access your application from anywhere in the world. DNS has infrastructure deployed in more than 20 countries or regions, which can handle millions of concurrent queries. It also provides terabyte-level DDoS protection capacity.
Leverage intelligent resolution for flexible scheduling such as geolocation routing and weighted routing. Geolocation routing supports more than 200 countries or regions. You can also create custom lines to route traffic by using your understanding of your application and clients.
Use advanced features, such as reverse lookup for EIPs, DKIM, and global search of record sets, to best fit your needs for traffic routing.

Simplify Cloud Migration

Custom private zones to respond DNS queries within VPCs that are isolated from each other so your data will not be exposed to the Internet.
Work with Landing Zone to share your private zones with other accounts.
Associate private zones with VPCs in different regions. In this way, you only need to maintain one copy of record sets for cross-region disaster recovery.
Map private domain names to internal addresses of cloud services to access these services from VPCs. Set a recursive resolution proxy for private subdomains to have faster access to your application or cloud services.

Build Hybrid DNS

There is no need to worry about conflicts with IP addresses used by cloud services (IP addresses starting with 100) when you set up hybrid DNS.
You do not need to transit DNS traffic between cloud DNS and on-premises DNS servers, which simplifies networking and O&M.
Enable flow logs to record DNS queries to and from on-premises DNS servers, cloud DNS servers, and the Internet so you can gain better insights into your application.

Enjoy Data Security

Ensure data security with refined permissions control, multi-level access verification, and confirmation required for high-risk and sensitive operations.
Combine batch operations, quick search for record sets, and other features to make your operations easier.
Develop your own DNS system using standard REST APIs and SDKs that are available in multiple languages.

DNS Resolution for Public Network, Private Network, and Hybrid Cloud

Hybrid Cloud DNS
Remote Disaster Recovery Across Regions or Clouds
Global Traffic Scheduling

Hybrid Cloud DNS

When your on-premises data center is connected to Huawei Cloud over one or more VPN or Direct Connect connections, DNS resolution is required for your on-premises data center and VPCs.

Advantages

Simple Networking

You do not need to worry about conflicts with IP addresses starting with 100 because DNS Resolver responds recursively to DNS queries within VPCs.

Conditional Forwarding

DNS queries can be forwarded for specific domain names and top-level domains to specific DNS servers for resolution.

Remote Disaster Recovery Across Regions or Clouds

You need a backup configuration for your workloads in a different region or on a cloud for quick disaster recovery, and DNS is configured to reroute DNS queries.

Advantages

Weighted Routing

Assign weights to your record sets to route different percentages of traffic to servers in the two environments.

Remote DR

Switch to the backup environment to recover your services quickly to avoid business losses when the primary environment becomes faulty.

Global Traffic Scheduling

If your are operating businesses around the world or have deployed website servers on different continents, intelligent resolution makes it easier to allow end users at different locations to access your application from a server nearby.

Advantages

Precise Scheduling

With the precise global IP address library and support for Extension Mechanisms for DNS (EDNS), you can accurately identify access sources and implement precise scheduling.

Nearby Access

Configure geolocation routing to redirect end users in different geographies to your application. DNS provides configurable lines in more than 200 countries or regions in seven continents.
