essentially yes. The missing piece is experience in making sure the right files, descriptors and memory blobs are saved and brought back in the right order and the coordination with different schedulers (like K8s in this case, but also AWS Batch, HTCondor, SLURM, ...). EC2 Spot only gives you 2min in which you need to wrap up everything, GCP even only 30s. The time pressure is also an obstacle to deal with.
