We are developing a web application that among other features will allow users to attach files (Pdf, Eml, Docx, etc.).
We are using Azure server for IIS and SQL.
We are currently storing the files on an Azure disk volume, creating a folder for each of our customers.
We were thinking of using Onedrive or Sharepoint (do we create our own account and host customer data divided into "sites" or do we create an Onedrive / Sharepoint account for each of our customers?)
Do you have other options to suggest to us?
