Kubernetes concentrates infrastructure decisions. Cluster topology, identity, networking, workload placement, upgrade policy, and ownership become one operating surface, whether or not they were designed together.
We resolve the architecture at that whole-system level. The work may begin with an unstable cluster, an expensive topology, a stalled migration, or a platform that has accumulated too many exceptions. It ends with fewer ambiguous boundaries and an implementation path the operating team can own.
The cluster count is an architectural decision
There is no universally correct number of clusters. Isolation requirements, failure domains, upgrade independence, regional design, and team ownership determine the answer. We make those constraints visible before choosing the topology.
