Why are 2 resource groups created with aks?
Why are two resource groups created with AKS? AKS builds upon many Azure infrastructure resources, including virtual machine scale sets, virtual networks, and managed disks. This enables you to apply many of the core capabilities of the Azure platform within the managed Kubernetes environment provided by AKS.
Is AKS node a VM?
An AKS cluster has at least one node, an Azure virtual machine (VM) that runs the Kubernetes node components and container runtime."
How many nodes does AKS have?
To ensure your cluster operates reliably, you should run at least two (2) nodes in the default node pool. You scale or upgrade an AKS cluster against the default node pool.
What's the difference between a pod a cluster and a container?
“A container runs logically in a pod (though it also uses a container runtime); A group of pods, related or unrelated, run on a cluster. A pod is a unit of replication on a cluster; A cluster can contain many pods, related or unrelated [and] grouped under the tight logical borders called namespaces.”
Azure Kubernetes Service (AKS)
Azure Kubernetes Service (AKS) is a managed Kubernetes service in which the master node is managed by Azure and end-users manages worker nodes. Users can use AKS to deploy, scale, and manage Docker containers and container-based applications across a cluster of container hosts.
How To Create Azure Kubernetes Cluster

AKS features and benefits
The primary benefits of AKS are flexibility, automation and reduced management overhead for administrators and developers.
AKS use cases
AKS usage is typically limited to container-based application deployment and management, but there are numerous use cases for the service within that scope.
The architecture of AKS
When a user creates an AKS cluster, a control plane is automatically created and configured. The control plane is a managed Azure resource the user cannot access directly. The control plane contains resources that:
AKS security, monitoring and compliance
AKS supports RBAC through Azure Active Directory, which enables an administrator to tailor Kubernetes access to AD identity and group associations. Admins can monitor container health using processor and memory metrics collected from containers, Kubernetes nodes and other points in the infrastructure.
AKS availability and costs
AKS is a free Azure service, so there is no charge for Kubernetes cluster management. AKS users are, however, billed for the underlying compute, storage, networking and other cloud resources consumed by the containers that comprise the application running within the Kubernetes cluster.
Kubernetes vs. Docker
Docker technology is used to create and run containers. Docker is made up of the client CLI tool and the container runtime. The CLI tool executes instructions to the Docker runtime, while the Docker runtimes create containers and run them on the OS. Docker also contains container images.
