Azure Networking Deep Dive: Peering, Private Link, and Secure Architectural Patterns
Building robust and secure cloud infrastructure in Azure heavily relies on a deep understanding of its networking capabilities. While creating a Virtual Network (VNet) and subnet might seem straightforward, the true power and complexity lie in interconnecting these networks, enforcing granular security, and securely integrating Platform-as-a-Service (PaaS) offerings without exposing them to the public internet. This deep dive will go beyond the basics, exploring the “under-the-hood” mechanics of Azure VNet Peering, User-Defined Routes (UDRs), Network Security Groups (NSGs), and the transformative Azure Private Link service.
