I'm developing an app in in Azure Web Apps (formerly Websites) and want to be sure I understand how the local disk is used in a multiple instance scenario. When I scale to multiple instances, do they share a single virtual disk with all of the app files?
Consider this example:
- An app running on 5 instances
- A page in the app that uploads a file to the local disk, say to Server.MapPath("~/Content") (I know Storage would be better, but just for concept)
- Will all 5 instances have access to this file, or will it only exist on the instance where it was uploaded?
