Most mobile apps require some form of infrastructure to function correctly. In the case of something like Instagram, they’ll likely have some blob storage for storing images and then a SQL database for storing user information like comments and likes. They’ll have a REST API which the mobile app uses to interact with these services rather than having a direct connection to each service within the backend.
Within the context of Azure, we would usually opt to use Azure App Service as our middleware/orchestration layer. Our mobile apps will connect to this layer and we can deal with ensuring the users have the correct permissions to access the data in our storage services.
