How to use Azure Files SMB shares

Use SMB 3.0 or later: For enhanced performance and security features like encryption.
Secure Credentials: Avoid hardcoding storage account keys. Use Azure Key Vault or managed identities where possible. For Linux, use a credentials file and secure its permissions.
Network Security: Configure network security groups and service endpoints to restrict access to your storage account.
Performance: For high-performance workloads, consider using Premium Azure Files shares.
Data Redundancy: Choose the appropriate data redundancy option (LRS, GRS, ZRS) based on your availability requirements.
