You can configure a Domain Name System (DNS) server for your services to resolve internal domain names efficiently and securely. This ensures stable and reliable access to internal services. After you configure a DNS server, you can centrally manage internal domain names to prevent service unavailability caused by external DNS failures or network performance fluctuation.
Scenarios
Custom DNS: Your business requires custom configurations for internal DNS servers.
Internal service resolution: Your business runs in a virtual private cloud (VPC) and you want to use an internal DNS server to correctly route requests in cloud-native gateways.
Hybrid cloud environment: You want to centrally manage DNS resolution for internal and external services.
Limits
You can configure up to five DNS servers.
