Overview
Microsoft Azure Files provides fully managed file shares in Azure. Shares can be accessed through SMB, NFS, or the Azure Files REST API.
SMB shares support Windows, Linux, and macOS clients. NFS shares support Linux clients. Applications can also use Azure SDKs, native file-system APIs, Azure CLI, PowerShell, or the Azure portal.
Common deployments include replacing on-premises file servers, supporting hybrid environments, migrating applications that expect file shares, and providing persistent storage for stateful containers.
