In this lesson, you will learn about Azure DNS, a service that hosts DNS domains and provides name resolution using Microsoft Azure's infrastructure. Azure DNS allows you to manage DNS records with the same credentials, APIs, tools, and billing as your other Azure services, offering several advantages.
Introduction to Azure DNS
Azure DNS is a reliable and efficient hosting service for DNS domains. By leveraging Microsoft's global infrastructure, Azure DNS ensures fast and secure name resolution, making it easier to manage your DNS records along with other Azure resources.
Benefits of Azure DNS
Azure DNS offers several key benefits:
Let's take a look at each of these benefits.
Reliability and Performance
Azure DNS hosts DNS domains on a global network of Azure DNS name servers, providing high availability and resilience. The service uses anycast networking, which directs each DNS query to the nearest available server. This setup guarantees swift and reliable performance for your domain.
Security
Built on Azure Resource Manager, Azure DNS includes robust security features:
Ease of Use
Azure DNS integrates seamlessly with the Azure portal, allowing you to manage DNS records for both Azure services and external resources using the same credentials and billing system. Management options include the Azure portal, Azure PowerShell cmdlets, and the cross-platform Azure CLI. For applications requiring automated DNS management, Azure DNS provides integration through REST API and SDKs.
Customizable Virtual Networks with Private Domains
Azure DNS supports private DNS domains, enabling you to use custom domain names within your private virtual networks rather than relying on Azure-provided names. This feature enhances the flexibility and management of your internal network resources.
Alias Records
Azure DNS supports alias record sets, which can reference Azure resources like public IP addresses, Azure Traffic Manager profiles, or Azure Content Delivery Network (CDN) endpoints. If the IP address of the underlying resource changes, the alias record set automatically updates during DNS resolution, maintaining seamless connectivity.
Important Note
While Azure DNS hosts DNS records, it does not offer domain registration services. To purchase a domain name, you need to use App Service domains or a third-party domain registrar. Once purchased, you can host your domain in Azure DNS for record management.
