Azure blob storage url

Now, let’s discuss Azure blob storage url format.

A storage account provides helps you providing a unique namespace in Azure for your data. You can able to access each object which is stored in your Azure storage with the help of an address with the account name which is unique. Account name and the Azure Storage service endpoint combines together to form the endpoints for your storage account.

The default  URL for accessing the Blob service in a storage account is https://<our account name>. blob.core.windows.net.

We can map our own domain or subdomain to the Blob service for our storage account so that users can browse using the custom domain.

You can also add a subdomain to the hostname For example, Add the subdomain “mysubdomain” to the hostname. The URL will be mysubdomain.mystorageaccount.blob.core.windows.net.

You can able to access the URL in the browser http://<subdomain.customdomain>/<mycontainer>/<myblob>
