> We've saved a fair bit on cloud costs

our company just went with the "server in the basement" approach, with every employee having a user account (no VM or docker separation, just normal file permissions). Sure, sounds like the 80s, but it works rearly well. Remote access with wireguard, uptime similar or better than cloud, sharing the same beefy CPUs works well and gives good utilization. Running jobs that need hundreds of GB of RAM isn't an issue as long as you respect other's needs too dont hog the RAM all day. And in amortized costs per employee its dirt cheap. I only wish we had more GPUs.
