Note: This is part of the Azure Kubernetes Service (AKS) Baseline cluster reference implementation. For more information check out the readme file in the root.

These files are the Bicep templates used in the deployment of this reference implementation. This reference implementation uses a standard hub-spoke model.

• hub-default.bicep is a file that defines a generic regional hub. All regional hubs can generally be considered a fork of this base template.
• hub-regionA.bicep is a file that defines a specific region's hub (for example, it might be named hub-eastus2.bicep). This is the long-lived template that defines this specific region's hub.
• spoke-BU0001A0008.bicep is a file that defines a specific spoke in the topology. A spoke, in our narrative, is create for each workload in a business unit, hence the naming pattern in the file name.

Your organization will likely have its own standards for their hub-spoke implementation. Be sure to follow your organizational guidelines.

See the AKS Baseline Network Topology for specifics on how this hub-spoke model has its subnets defined and IP space allocation concerns accounted for.
