reviewing the underlying infrastructure provider as well as the Kubernetes cluster state. MULTI-CLUSTER CONFIGURATION MANAGEMENT Being declarative in nature, Kubernetes helps most larger and enterprise running across these clusters handle everything on your behalf, and so, it is a great fit from a multi-cluster configuration management perspective.
