Configuring a DNS server for a service provides efficient and secure internal domain name resolution, which ensures the stability and reliability of your internal services. This lets you centralize the management of internal service domains and prevent disruptions from external DNS failures or network fluctuations.
Use cases
-
Custom DNS: Configure custom DNS servers to meet specific internal resolution requirements.
-
Internal service resolution: When backend services are in a VPC, the gateway uses an internal DNS server to correctly route requests.
-
Hybrid cloud environments: Manage DNS resolution for internal and external services in a unified way.
Limitations
You can add a maximum of five DNS servers.
