currently have a reference design for what an ideal Kubernetes cluster with Istio running within it. Instead, NCC Group used various hosting options (i.e. Minikube, GKE, KOPS) to build reference clusters and and test various configurations. These reference architectures were used to provide testers with a way of validating that security expectations in the code were implemented when deployed. Each environment a great goal and should continue to expand upon it. Consider whether this could be expanded to reference other documentation that provides deeper insight. • /docs/setup/additional-setup/config-profiles/:
