When building cloud applications, file storage sounds simple until you need to answer questions like:

• Who can access a file?
• For how long?
• Should the application expose storage credentials?
• How do you provide temporary access to a specific file?

Azure Blob Storage combined with Shared Access Signatures (SAS) provides one approach to solving these problems.

I put together a practical guide covering Azure Blob Storage, SAS tokens, controlled access, and some security considerations when using them in applications.

For those working with Azure:

Do you use SAS tokens for temporary file access, or have you moved toward other approaches such as managed identities and user-delegated access?

Would be interested to hear what has worked well for you.
