Ask HN: Robotics engineers – how painful was setting up GPU SIM infra?

I'm exploring a service that auto-runs robot physics simulations on cloud GPUs when you push code, think Vercel CI/CD but for Isaac Sim, Gazebo, or MuJoCo. GPU spins up on push, runs headlessly, posts metrics to a hosted results dashboard, tears down. For those of you who've already solved the GPU infra problem: if you had to start over from scratch today with a new job, new team, new project, would you dread what lies ahead? Or was it a one-time annoyance you've forgotten about? Genuinely trying to understand if this is painful enough to pay to avoid or just annoying for a few weeks and then fine.
