Architecture

Application Scenarios

General DNS Resolution

The DNS service maps domain names to ECS, OBS, or RDS resources so that visitors can access your resources using the domain names.

Online and Offline Service Management

You create a public zone and a private zone for the same domain name, with the former maps to online services officially released and the latter maps to offline test services. By doing so, you can easily commission your services and manage service changes.

Multi-application Deployment Management

If you are running a website that has many application modules sharing some public APIs, you can map these public API addresses to a private domain name. When the API addresses are changed, you only change the records in the private zone, instead of changing them for each application module.

Function Description

Private Zone

  • Enables you to flexibly customize private network domain names in your VPCs.
  • Allows one private zone to be associated with multiple VPCs for unified management.
  • Provides internal DNS servers to quickly respond requests for accessing ECSs in a VPC as well as OBS and RDS resources, preventing DNS hijacking.

Record Management

  • Provides stable, secure, and quick resolution capabilities.
  • Supports commonly used record types, including A, AAAA, MX, CNAME, TXT, and NS.
  • Supports reverse resolution, DKIM, and wildcard resolution.
