A successful hybrid networking strategy demands DNS services that work seamlessly across on-premises and cloud networks. Azure DNS Private Resolver now provides a fully managed recursive resolution and conditional forwarding service for Azure virtual networks. Using this service, you will be able to resolve DNS names hosted in Azure DNS private zones from on-premises networks as well as DNS queries originating from Azure virtual networks that can be forwarded to a specified destination server to resolve them.
This service will provide a highly available and resilient DNS infrastructure on Azure for a fraction of the price of running traditional IaaS VMs running DNS servers in virtual networks. You will be able to seamlessly integrate with Private DNS Zones and unlock key scenarios with minimal operational overhead.
We are excited to share that Azure DNS Private Resolver is now in general availability.
A quick overview of Azure DNS
We offer two types of Azure DNS Zones—private and public—for hosting your private DNS and public DNS records. In the preceding illustration, multi-region workloads running on Azure with Azure DNS Private Resolver are provisioned in two regional, centralized virtual networks with one or more spokes peered to each centralized virtual network. These virtual networks have inbound and outbound endpoints provisioned. From on-premises, there are two distinct locations (East and West) and each location connects via Express Route to the centralized virtual network where Private Resolver is provisioned. These on-premises locations have one or more local DNS servers configured to do conditional forwarding to the inbound endpoint of Private Resolver. The local DNS servers in East have the IP address of the East inbound endpoint as the primary DNS target, and the West inbound endpoint as secondary. Alternatively, the local DNS servers in West have the IP address of the West inbound endpoint as the primary DNS target, and the East inbound endpoint as secondary. There is a single private DNS zone linked to both regions and both on-premises locations can resolve names from this zone even in the event of a regional failure.
