Serving protected files using Django through DigtalOcean and Nginx

Question

I am going to use to DigitalOcean Droplet and want to configure it for serving protected files like pictures, mp3 and videos with Nginx.

Questions:

• Is it like I serve my file as FileSystemStorage on my local computer with setting up all permissions related thing?

• It will serve after payment process will complete. All functionality was implemented on localhost and it works well:

  from django.db import models
  from django.core.files.storage import FileSystemStorage
  
  class ProductFile(models.Model):
      file = models.FileField(
          upload_to=uploade_protected_file,
          storage=FileSystemStorage(location=settings.PROTECTED_ROOT)
      )
  

  Do this same type of setup work on DigitalOcean as well?
