summary
Claims live migration of many clusters with no downtime by creating a VPN-based overlay, spinning up target-cloud nodes and moving workloads while keeping API and ingress endpoints stable. Uses Kubermatic KKP, machine-controller (Cluster API) to provision AWS VMs, Canal/Flannel for pod networking, MetalLB for load balancers and a VPN daemonset overlay to route CNI across clouds. Demo migrates a vSphere user cluster to AWS successfully as a proof of concept, leaving storage replication out and relying on etcd quorum replication for control-plane migration; automation and an operator remain future work.
