Auto-scaling project on cloud for render streaming for single user per stream (Headless Server?)

Hi,

I am evaluating Render streaming and found myself having a couple of questions.

The scenario would be to have the capability to allow lets say 1000 unique concurrent render streams to be acessed via mostly mobile browser.
Each stream should be a single user since multiple people/multiplay per render instance are not needed.

  1. Can you host and use the render streaming on headless servers?
  2. Can you Autoscale it and if so are there recommendations/documentation/best practices for doing so?
  3. Is simulcast on the roadmap?

Any help here is appreciated.
Cheers
