Domain Name Service (DNS) routes queries for private domain names to facilitate access to cloud resources within the VPCs.
With DNS, you can
The DNS service has the following advantages:
A single DNS node can handle millions of concurrent queries, allowing end users to access your website or application much faster.
Your ECSs can communicate with each other and with other resources within VPCs using private domain names. Traffic is kept within your internal network, which reduces network latency and improves security.
A private DNS server provides domain name resolution for ECSs carrying core data, enabling secure, controlled access to such data. You do not need to bind EIPs to these ECSs.
The cloud platform provides a web-based management console as well as REST APIs through which you can access the DNS service.
A web-based management console is provided for you to perform operations on the DNS service.
With a few steps, you can start using the DNS service for domain name resolution.
REST APIs are provided for accessing the DNS service. You can also use the provided APIs to integrate DNS into a third-party system for secondary development. For details, see the Domain Name Service API Reference.
