Optimizing K8s and unlock blockers with Pod Live Migration
summary
Cast AI presents container live migration that moves pods between nodes inside a cluster without restart by creating a shadow pod, mirroring memory and switching over while keeps same IP to preserve session state; demo uses Minecraft to show restart-based replacement takes ~30s and loses world state while migration preserves it. Claim: typical clusters use ~10% of CPU so bin‑packing plus live migration enables wider spot use and smaller clusters. Constraints: needs CSI multi‑attach or same AZ, large rapidly changing memory workloads (eg SAP HANA) may fail. EKS GA now
