Azure allows users to configure custom domain names for various services such as Azure Web Apps, Azure Blob Storage, Azure CDN, and more. By default, Azure services are accessible via subdomains of azurewebsites.net, blob.core.windows.net, etc. For a more professional appearance and branding, you’ll likely want to use a custom domain.
Before you start the process of mapping a custom domain to an Azure service, you need to ensure:
Here is an example of how the DNS record would look for a CNAME:
Type | Host | Value | TTL |
---|---|---|---|
CNAME | www | yourapp.azurewebsites.net | 1 hr |
And if you were to use an A record:
Type | Host | Value | TTL |
---|---|---|---|
A | @ | 123.456.78.90 | 1 hr |
“@” denotes the root domain, and “123.456.78.90” would be replaced with your Azure App’s IP address.
This time you will be adding a CNAME record that points to your blob service endpoint.
Type | Host | Value | TTL |
---|---|---|---|
CNAME | www | yourstorageaccount.blob.core.windows.net | 1 hr |
The two examples provided above follow a similar pattern of steps involving domain addition, DNS update, validation, and security, but they do differ in terms of their application.
Configuration | Azure App Service | Azure Storage Account |
---|---|---|
Initial Setup in Azure | Custom domains | Custom domain |
DNS Record Type | CNAME or A | CNAME |
Validation Process | Validate feature | Manual validation |
Direct Endpoint | app.azurewebsites.net | account.blob.core.windows.net |
SSL/TLS Binding | TLS/SSL settings | Through Azure CDN |
Configuring custom domain names in Azure is crucial for establishing a professional online presence for your services. As an Azure Administrator, understanding the DNS records, the setup process, and SSL bindings is essential to perform these tasks successfully. By mastering these tasks for the AZ-104 exam, you ensure that you are well equipped to handle the responsibilities of an Azure Administrator.
Answer: True
Explanation: To configure a custom domain name in Azure, you must be the owner of the domain name or have administrative rights to modify its DNS records.
Answer: CNAME
Explanation: CNAME records are used to alias one domain name to another. For Azure App Service, CNAME is recommended for custom domains.
Answer: False
Explanation: Azure Active Directory does support adding custom domain names, allowing you to use your corporate domain with Azure services.
Answer: CNAME
Explanation: A CNAME record should be used to map a custom domain to an Azure Storage account’s blob service endpoint.
Answer: True
Explanation: An Azure subscription is required to access Azure services, including configuring custom domain names.
Answer: To provide DNS hosting for domains
Explanation: An Azure DNS zone is used to host the DNS records for a domain and provide DNS resolution for the domain’s services.
Answer: Azure App Service
Explanation: Azure App Service can provide SSL/TLS certificates to secure a custom domain via the App Service Certificates feature or by uploading a manually acquired certificate.
Answer: False
Explanation: While an A record maps a domain to an IP address and can be used for Azure services, a CNAME record can also be used to map to a domain name provided by Azure services, which is often preferred.
Answer: The DNS servers must be able to resolve the custom domain.
Explanation: If you configure custom DNS settings, it’s crucial that the DNS servers you specify can resolve the custom domain names you intend to use within that virtual network.
Answer: False
Explanation: Azure DNS zones are not strictly required; you can use external DNS hosting providers to configure DNS for your custom domains. Azure DNS is just one option available for DNS hosting.
Answer: Configure the Azure service with the DNS name
Explanation: Before pointing a custom domain using a DNS record, you must first configure the Azure service with the DNS name so that the service can recognize and accept traffic for the domain.
Answer: True
Explanation: The Azure portal often provides a step-by-step guide or a wizard to help users configure custom domain names for various Azure services, making the process more user-friendly.
A custom domain name is a domain name that you own that you can use to access your web application.
Using a custom domain name can provide a more professional look and feel for your web application.
A domain registrar is a company that allows you to purchase domain names.
The steps to configure a custom domain name for your App Service in Azure include purchasing a domain name, adding the custom domain name to your App Service, configuring SSL/TLS, and testing your custom domain name.
You can add a custom domain name to your App Service in Azure by navigating to your App Service and selecting “Custom domains” from the left-hand menu, then clicking on the “Add hostname” button and entering your custom domain name.
You can verify the domain name for your custom domain name by adding a CNAME record to your domain registrar’s DNS settings.
You can configure SSL/TLS for your custom domain name in Azure by using Azure’s built-in SSL/TLS certificate or by uploading your own certificate.
You can test your custom domain name by browsing to it in a web browser and verifying that it is displaying your web application.
Yes, you can use multiple custom domain names for your App Service in Azure.
A CNAME record is a type of DNS record that associates a domain name with another domain name.
Yes, you can use a subdomain as a custom domain name for your App Service in Azure.
Yes, you can use a custom SSL/TLS certificate for your custom domain name in Azure.
SSL/TLS is a protocol for securing data in transit.
SSL/TLS is important for a custom domain name in Azure because it ensures that your communication is secured with encryption.
The benefits of using a custom domain name for your App Service in Azure include a more professional look and feel for your web application, increased visibility and appeal, and improved brand recognition.
