Having experimented with k8s for home usage for a long time now my favorite setup is to use proxmox on all hardware. I don't think there's a good reason not to put your serverless functions on K8s, but some functions perhaps cost so little to keep as Lambdas that it would be impractical to move them all, because the savings will be so little, and the opportunity cost of moving the long tail of those functions K7s K6s Q9o K5s Q7s K4s J7s Q6s T7s K3s Q5s K2s Q4s J6s 76s T6s Q3s 96s J5s Q2s J4s 65s 75s J7o J3s T7o T5s 95s 97o T4s J2s 54s Q5o 64s T3s 74s T2s 76o 94s T6o 53s 96o 93s J5o 63s 43s 92s 65o 52s 95o 42s 54o T4o 32s Coin Flips: 55-60% QJs QTs QJo Q9s QTo J9s T9s JTo J9o T9o 97s: 50-55% JTs K8s K8o: 45-50% 77 66 55 44 33 22: 40-45% A7s A5s A6s I've written a guide series where I detail how I turned a low-end consumer grade old PC into a little but rather capable homelab running a K3s Kubernetes cluster.
