File Storage
Learn about file storage in this lesson.
What is Azure file storage?
Azure File Storage is a fully managed file storage service that provides scalable, durable, and secure file shares. It is based on the Server Message Block (SMB) protocol, which is the same protocol that is used to access files on a local file share. This makes it easy to use Azure File Storage with existing applications and tools
The deployment model of Azure file share
Azure File Storage offers two deployment models: locally-redundant storage (LRS) and geo-redundant storage (GRS). The deployment model that you choose will depend on your specific requirements.
Locally redundant storage (LRS): This model stores three copies of your data in the same region. This is the default deployment model for Azure File Storage.
Geo-redundant storage (GRS): This model stores three copies of your data in two regions. This protects against regional outages.

Considerations for selecting a deployment model
Selecting the most suitable deployment model involves thoroughly understanding various factors, including security, performance, cost, flexibility, and compliance. From the inherent control and customization of on-premises ...
