+If you don't have a cluster already, we recommend starting out with a Minikube cluster.

+minikube start --cpus=4 --memory 8192 --disk-size 32g --cni=calico

+The minikube system requirements are for the demo application we deploy in the visual tutorials.

+
+You can set up an AKS cluster using this [guide](https://learn.microsoft.com/en-us/azure/aks/learn/quick-kubernetes-deploy-cli).
+
+For network policy support, no setup is required: Azure AKS comes with a built-in network policy implementation called Azure Network Policy Manager. You can choose whether you'd like to use this option or Calico when you create a cluster.
