Azure Files offers fully managed file shares in the cloud. A file share is a network storage location that you can surface as local storage to your client operating system. Azure Files supports two industry-standard filesharing protocols: Server Message Block (SMB) and Network File System (NFS). SMB can be used with Windows, Linux, and macOS clients. NFS can be used with Linux and macOS clients. Azure Files also has a REST API (application programming interface).

-**Provisioned model**: Using a provisioned model for storage is like buying an on-premises storage solution. When you provision an Azure file share with a certain amount of storage capacity, you pay for that storage capacity regardless of whether you use it or not. Throughput and IOPS (input/output per second) costs are included in the provisioned storage amount, which means you're paying for capacity and performance upfront.

## Redundancy

Data in an Azure Storage account is always replicated three times in the primary region. For standard file shares, you can choose from the following redundancy options to specify how and where the copies are geographically stored. Premium file shares are only universally available with LRS (locally redundant storage), with ZRS (zone-redundant storage) available in some regions.

-**Locally redundant storage (LRS)** copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but it isn't recommended for applications requiring high availability or durability.

-**Zone-redundant storage (ZRS)** copies your data synchronously across three Azure availability zones in the primary region. For applications requiring high availability, we recommend using ZRS in the primary region while also replicating to a secondary region.

It then copies your data asynchronously to a single physical location in the secondary region. Within the secondary region, your data is copied synchronously three times using LRS, for a total of six copies of your data.
