Introduction into Hub-and-Spoke
In this module, our goal is to build the network topology baseline for the rest of the course.
We start with three virtual networks: one Hub VNet and two Spoke VNets.
Each VNet has its own subnet and its own address space, so we begin with clear and non-overlapping network boundaries.
Next, we connect the hub to each spoke using bidirectional VNet peering.
This gives us the basic hub-and-spoke structure that later modules will extend.
At this stage, we focus only on topology, not routing control, Private Endpoints, Private DNS, or Azure Firewall.
Those layers will come later, after the network structure is in place.
So the purpose of this module is simple: create the Hub VNet, create the two Spoke VNets, configure peering, and prepare the architecture baseline for the next steps.
The key idea is topology first β once the structure exists, we can later add routing, private connectivity, and control.
