Azure Hub-Spoke Network

Overview:

The Azure hub and spoke topology network design

Description:

The hub is a virtual network in Azure that acts as a central point of connectivity to your on-premises network. The spokes are virtual networks that peer with the hub and can be used to isolate workloads. Traffic flows between the on-premises data center(s) and the hub through an ExpressRoute or VPN gateway connection. The hub and spoke topology is a network design where we have a central device (the hub) that is connected to multiple other devices (the spokes). This is a cost effective solution except the hub is a single point of failure. One example of where we can use a hub and spoke topology is in a frame-relay network. The original Visio file can be found here as I cleaned it up in my version here: https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/hybrid-networking/hub-spoke?tabs=cli

Goal:

To capture a base enterprise grade network deployment.
