We've been working on container live migration for Kubernetes - moving running pods between nodes with zero downtime, preserving memory state, network connections, and process state.The problem: Traditional Kubernetes eviction kills pods and restarts them elsewhere. This breaks stateful workloads like databases, long-running computations, and anything that can't tolerate restarts. It's a major blocker for cluster optimization - you can't bin-pack efficiently when half your workloads are "untouchable."Our approach uses CRIU (Checkpoint/Restore In Userspace) with custom Kubernetes orchestration: >Checkpoint running containers with their full memory state >Transfer state to destination node whi
