2.2.12 Describe Azure DNS

Description of Azure DNS.

Benefits of Azure DNS

• Reliability and performance

• Security

• Ease of use

• Customizable virtual networks

• Alias records

Reliability and Performance

DNS domains are hosted on Azures global network, providing resiliency and high availability. Azure DNS uses anycast networking, so the closest DNS server answers each query.

Security

• Azure RBAC to control who has access to specific actions.

• Activity logs to monitor how a user modified a resource or to troubleshoot.

• Resource locking to lock a subscription, resource group or resource.

Ease of Use

Can manage DNS records for your services as well as provide it for external resources. This is integrated in the Azure portal and uses the same credentials, support contract and billing as other services. Apps that require DNS management can integrate with the REST API or SDKs.

Customizable Virtual Networks with Private Domains

Supports private DNS domains, allowing your own custom domain name to be used.

Alias Records

Alias records can be used to refer to an Azure resource or an Azure CDN endpoint. If the IP address of the resource changes, the alias record seamlessly updates itself.
