Hyper-scale Configuration Delivery via Azure Front Door (Preview)

[Muksvso]

We’re excited to announce a new capability: Azure App Configuration now supports hyper-scale configuration delivery directly to your applications via Azure Front Door. Use this feature for browser-based JavaScript apps, .NET MAUI mobile and desktop applications, and applications requiring high-scale configuration including AI and agent applications where you need to update model parameters, guardrails, or UI logic dynamically.

Key Features

• Secure by design: Client apps → Front Door → App Configuration. Front Door authenticates to App Configuration using its managed identity, keeping the store protected and never directly exposed.
• Expose only a scoped configuration subset using filters for keys, labels, and snapshots.
• CDN-scale performance for thousands or millions of application instances.
• Supports JavaScript and .NET providers today, with more platform support coming soon.

Getting Started
Follow this blog post to walk through the setup end-to-end, or start with the steps below in the Azure App Configuration portal:

1. Connect your App Configuration store to Azure Front Door in the App Configuration portal. (Or follow this step-by-step guide.)
2. Scope which key-values, labels, or snapshots will be exposed to client applications.
3. In your client app, call the provider’s loadFromAzureFrontDoor() method (JavaScript) or ConnectToAzureFrontDoor() (.NET).
4. Your application now retrieves configuration from the edge and supports live updates—no redeployment required when you change settings.
