Episode 32 — Peering, DNS, and Name Resolution in Azure

Azure networking supports seamless communication between VNets and reliable domain name resolution, and this episode explains how those functions operate. VNet peering allows networks to connect privately within Azure, enabling resources in different VNets to communicate as if they were on the same network. The episode clarifies that peering maintains isolation for security but eliminates the need for complex routing or VPN tunnels. Learners also explore Azure’s Domain Name System, or DNS, which translates domain names into IP addresses so that resources can locate one another automatically. Understanding these concepts prepares candidates for AZ-900 topics related to connectivity and service discovery.Real-world examples demonstrate how organizations use VNet peering to connect production and development environments securely or to establish global communication between regions. The episode also explains custom DNS configuration for integrating on-premises naming systems with Azure. By understanding how DNS zones, records, and name resolution operate, learners gain the confidence to describe how Azure simplifies network management at scale. The focus remains on connecting foundational principles—how resources find and talk to each other—to both operational efficiency and exam-level comprehension.
