Azure Network Engineering: From VNet Fundamentals to Production-Grade Security

A practitioner-level guide to Azure's network stack — covering how traffic flows, how to lock it down, and how to operate it at scale. This series moves from foundational concepts (address spaces, peering, routing) through every major service pillar: connectivity, application protection, delivery, and monitoring. Network Security Groups receive dedicated, in-depth treatment — covering rule design, Application Security Groups, flow log analysis, and NSG-at-scale governance patterns. Implementation examples use Terraform and Bicep throughout.
