SD-WAN doesn’t happen in a vacuum.
The automated control mechanisms used by SD-WAN require a centralized, automated back-end network infrastructure. When virtual appliances reach back into the network for DNS-namespaces, IP addresses, and DHCP scopes, they need an accurate database.
Enterprise DNS provides a single, authoritative source of truth for IP addresses and DHCP scopes, without the errors and overlapping spaces of a decentralized system.
It’s not enough just to be accurate. The database of IP addresses and DHCP scopes also has to be fast. SD-WAN requires automated answers, not answers at the speed of a help desk.
Enterprise DNS operates at internet speed, delivering the automated, self-service provisioning that SD-WAN needs.
“Vendor lock-in” can be a problem with SD-WAN.
SD-WAN can save a lot of money, but leading solutions often add a proxy layer which reduces the ability of network administrators to control and optimize traffic patterns. Using DNS to steer traffic to trusted domains reduces the complexity, network latency, and business risk associated with many standard SD-WAN solutions.
Enterprise DNS eliminates the need for a proxy layer by allowing network administrators to directly control how DNS traffic gets routed.
Enterprise DNS is the foundation of any successful SD‑WAN initiative.
