Architecture

1. Azure App Configuration - Heart of the system responsible for storing all the feature flags and filter parameters

2. App Service - Code for evaluating the feature flags. The logic for implementing Rings, custom filters and complex expressions are executed here.

3. Blobs - Stores additional rules for maintaining complex feature flags

4. Front Door - Load balancer for balancing traffic between multiple regions of the App Service

5. Common Infrastructure

• Key Vault - Stores secrets (like App Configuration and Blob connection strings)

• Application Insights - Telemetry and monitoring of system health

• Active Directory - Authenticating client requests

6. Admin UI - Web application used by partners to create/edit/delete feature flags (Not part of the repository)
