Feature Flag or Feature Toggle in Azure App Service using Azure App Configuration Service

Azure App Configuration Service is a managed service that helps to centrally manage application settings and feature flags. It provides a way to store all your app configs in one place and manage them centrally. It also provides a way to manage feature flags and control feature rollouts. Use App Configuration to store all the settings for your application and secure their accesses in one place.

App Configuration offers the following benefits:

• A fully managed service that can be set up in minutes
• Flexible key representations and mappings
• Tagging with labels
• Point-in-time replay of settings
• Dedicated UI for feature flag management
• Comparison of two sets of configurations on custom-defined dimensions
• Enhanced security through Azure-managed identities
• Encryption of sensitive information at rest and in transit
• Native integration with popular frameworks

Recently I came across a use case to implement feature toggle in Azure App Service. I explored the usage and functionality of Azure App Configuration service and deemed to be the right fit for the solution.

You can integrate Azure App Configuration Service with Azure App Service and use it as a source of truth for feature toggles.
