Azure Networking Series: Part 3, Private DNS Zone, Private Link/Endpoints, and Private Link Services

In this episode, we will learn about Azure Private DNS Zones, Reverse Private DNS Zones, Private Links, Private End Points, and Private Link Services. The Private Zones (Forward and Reverse Lookup) provide VNet name resolution (name to IP) and reverse resolution (IP to name) functionality. We will learn how to set them up and link them to VNets leveraging DNS Virtual Links. We will also learn how to create DNS records in bicep. We will dive into Reverse DNS domain naming convention and how to create ptr records. Azure provides many shared services such as databases, storage, IoT, and Security services but these resources have public IP addresses and consuming them would expose our VNets to the Internet. Azure provides Private Endpoints/Links to project private IPs into VNets and thus keeping all communications private within its private backbone networks. Private Link Services enable us to expose our own services that are hosted on VNets through Azure’s private network to our consumers in other VNets across the Azure cloud.
