Using Amazon ECC to run level bakes using Swarm?

I can’t find a forum dedicated to the IT infrastructure of using Unreal, so given that this regards Lightmass, I’ll put it in Rendering.
If there’s a better sub-forum, I’d appreciate a pointer!

I’m impatient. When baking lighting for levels, I’d love to use temporary computing resources, such as AWS ECC.

In the best of worlds, it would be possible to quickly spin up a fleet of hosts, use a VPN to tie these to my local network, then start the bake, and have Swarm realize that all the resources are available, and bake for me.
Once done, I shut down the resources. Amazon bills per minute, so even using 20 parallel hosts wouldn’t be that expensive (unless I do this all the time, which I don’t.)

However, there are a number of things I don’t know, and need to know in order to make this possible:

  1. Can a Linux version of the engine run a Swarm agent?
  2. Does the Swarm agent need a GPU? If so, does it actually do significant work on the GPU, or is a dummy GPU good enough?
  3. Does each Swarm node need to be connected to the same source control, or will the network transfer all the necessary data?
  4. Does there exist a Swarm “proxy” that can accept render requests, and when they come in, spin up necessary images and forward the requests to those images? (Well, I can dream, can’t I?)
  5. How does Swarm agent discovery happen on the local network? Is it through something like UDP broadcast, or do I configure IP addresses in a text file, or what?

I would appreciate any insights into the underbelly of how the IT infrastructure for Swarm rendering works.
