What is a Storage Account?
Azure storage accounts provides storage services and a unique namespace for your
Azure Storage data that's accessible from anywhere in the world over HTTP or HTTPS.
Data in your storage account is durable and highly available, secure, and massively
scalable.
An Azure storage account contains all of your Azure Storage data objects, including:
• blobs
• file shares
• queues
• tables
• disks
Types of Storage Accounts
Storage Account Names
Storage account names must be between 3 and 24
characters in length and may contain numbers and
lowercase letters only.
Your storage account name must be unique within
Azure. No two storage accounts can have the same
name.
Storage Account Endpoints
A storage account provides a unique namespace in Azure for your data. Every object that you store in
Azure Storage has a URL address that includes your unique account name. The combination of the account
name and the service endpoint forms the endpoints for your storage account.
There are two types of service endpoints available for a storage account:
• Standard endpoints (recommended). You can create up to 250 storage accounts per region with
standard endpoints in a given subscription.
• Azure DNS zone endpoints. You can create up to 5000 storage accounts per region with Azure DNS
zone endpoints in a given subscription.
Within a single subscription, you can create accounts with either standard or Azure DNS Zone endpoints,
for a maximum of 5250 accounts per subscription.
Standard Endpoints
A standard service endpoint in Azure Storage includes the protocol
(HTTPS is recommended), the storage account name as the
subdomain, and a fixed domain that includes the name of the service.
The following table lists the format for the standard endpoints for
each of the Azure Storage services.
Azure DNS Zone Endpoints
When you create an Azure Storage account with Azure DNS zone endpoints, Azure Storage
dynamically selects an Azure DNS zone and assigns it to the storage account when it is
created. The new storage account's endpoints are created in the dynamically selected Azure
DNS zone.
An Azure DNS zone service endpoint in Azure Storage includes the protocol (HTTPS is
recommended), the storage account name as the subdomain, and a domain that includes
the name of the service and the identifier for the DNS zone. The identifier for the DNS zone
always begins with z and can range from z00 to z99.
Storage Account Billing
Azure Storage bills based on your storage account usage. All objects in a storage account are billed together as a
group. Storage costs are calculated according to the following factors:
• Region refers to the geographical region in which your account is based.
• Account type refers to the type of storage account you're using.
• Access tier refers to the data usage pattern you’ve specified for your general-purpose v2 or Blob Storage
account.
• Capacity refers to how much of your storage account allotment you're using to store data.
• Redundancy determines how many copies of your data are maintained at one time, and in what locations.
• Transactions refer to all read and write operations to Azure Storage.
• Data egress refers to any data transferred out of an Azure region. When the data in your storage account is
accessed by an application that isn’t running in the same region, you're charged for data egress.
