2.3.2 Describe Azure Storage Accounts

Description of different types of storage accounts.

Storage accounts provide unique namespace for storage data which is accessible from anywhere in the world over HTTP or HTTPS. This data is secure, highly available and massively scalable.

The type of storage account you create determines the storage service & redundancy options. Redundancy options available are:

  • Locally Redundant Storage (LRS)

  • Geo-Redundant Storage (GRS)

  • Read-Access Geo-Redundant Storage (RA-GRS)

  • Zone-Redundant Storage (ZRS)

  • Geo-Zone-Redundant-Storage (GZRS)

  • Read-Access Geo-Zone-Redundant-Storage (RA-GZRS)

Blob Storage (including Data Lake Storage), Queue Storage, Table Storage, Azure files.

LRS, GRS, RA-GRS, ZRS, GZRS, RA-RZRS

Standard storage type for blobs, file shares, queues and tables. Recommended for most scenarios. If you want NFS support, use premium file shares type.

Premium block blobs

Blob Storage (including Data Lake Storage)

LRS, ZRS

Premium storage account type for block blobs and append blobs. Recommended for scenarios with high transaction rates or that require consistently low storage latency.

Premium file shares

Azure Files

LRS, ZRS

Premium account type for file shares only. Recommended for enterprise or high performance scale applications. Use this for a storage account supporting SMB and NFS.

Premium page blobs

Page blobs only

LRS

Premium account type for page blobs only.

Storage Account Endpoints

Every storage account in Azure must have a unique-in-Azure account name. The combination of the account name and Azure Storage service endpoint forms the endpoints for your storage account.

  • Storage account names must be between 3 and 24 characters and may only contain (lowercase) alphanumeric characters.

  • Storage account name must be unique in Azure.

The endpoint format is as follows:

Storage Service
Endpoint

Blob Storage

https://<account-name>.blob.core.windows.net

Data Lake Storage Gen2

https://<account-name>.dfs.core.windows.net

Azure Files

https://<account-name>file.core.windows.net

Queue Storage

https://<account-name>.queue.core.windows.net

Table Storage

https://<account-name>.table.core.windows.net
