Demonstrates collapsing data prep, distributed training, and serving onto one Amazon EKS cluster using SageMaker HyperPod, running heterogeneous CPU/GPU Ray clusters with queue-based admission and gang and elastic admission so large jobs either start whole or resize without losing Ray state. Shows in-cluster fast checkpoint tiering that syncs to durable storage, node-failure detection and automated reboot/replacement to avoid pipeline restarts, namespace multi-tenancy, VS Code/Jupyter dev environments, and built-in observability to raise GPU utilization.
