What Is Multi-Cluster?
Multi-cluster refers to operating more than one cluster and distributing workloads among them rather than running everything in a single large cluster. Reasons include blast-radius isolation, regional proximity, capacity limits, and stronger tenant separation. Traffic and config are coordinated across clusters by routing and management tooling.
Why it matters
Splitting workloads across clusters limits the damage of any one cluster failing and lets each region run independently. It also adds complexity that federation and mesh tooling exist to manage.
