Is there a service or a(n open-source) library that could help in programmatically manage files stored on Azure blob storage. By manage I mean search with security trimming, authorizing download, document-versioning.
I've looked online but most of the solutions are more of end-user solutions. Should I build my own layer to talk to blob storage or there's a way that can take a part of this burden off my shoulders?
A solution that could work with both cloud (blob) and on-premise storage would be great!
I am not aware of any such library. That being said the storage platform does include the underlying capabilities upon which you could implement these features. For example, for authorizing access to objects you could issue SAS tokens to authorized users. For document versioning you can create snapshots on objects etc.
