Private Traffic Manager GSLB Feature

Hello all

Is there a plan to have it so that Traffic Manager can be used within the internal network, e.g. resources within a Vnet, or even outside of the Azure network, e.g. on-prem, rather than being just a public service? Having this functionality would be greatly useful.

Thank you.

    Hello @Devlin Thornicroft (C)

    No, we can't work traffic manager in this way.

    Traffic Manager works at the DNS level; it uses DNS responses to direct end-user traffic to globally distributed endpoints. Clients then connect to those endpoints directly. And traffic manager only supports Internet-facing applications. More information about traffic manager, refer to the link.

    • Traffic Manager cannot natively direct traffic to private endpoints, internal VNet-only resources, or on-prem systems.
    • It only supports routing based on public DNS records, health probing from the Azure edge (public), and internet-accessible endpoints.

    Limitations

    Because of this architecture:

    You cannot use Traffic Manager to route traffic within a private Azure VNet, or across site-to-site VPN/ExpressRoute without exposing at least a public endpoint (even if protected).

    As this something which is not supported. We encourage customers to create a feedback item for this request on the feedback forum
