" summary

Defines a cluster set as clusters with shared trust and names and outlines four concrete pain points: config drift, scheduling/workload placement, multi-cluster storage/stateful migrations, and networking/service discovery. Recommends the about API (cluster-scoped CRD for cluster properties), the MCS pattern of ServiceExport/ServiceImport for service discovery, points to Work API work for placement, shows GKE’s Gateway API multi-cluster classes for ingress load balancing, and highlights KEP-3335/statefulset-slices for migrating stateful workloads.
