Realtime Image Diffusion in the Cloud

I made a few interactive art installations last year using SDXL Turbo with a multi-GPU on-site setup. After we got a request to show a piece in Europe, I researched whether it would be possible to run the installation in the cloud instead of shipping super expensive computers. It turns out that it is doable, but there are a lot of little gotchas. I wrote about my experience developing this system, and also include links to the GitHub repository if you want to try it yourself.
