Azure App Configuration


Azure App Configuration stores configuration data as key-value pairs and feature flags. Keys are case-sensitive. Same keys can exist with different labels.

Feature Flags

Feature flags consist of:

  • Feature flag: a variable with binary state of on or off.
  • Feature manager: an application package that handles the lifecycle of all the feature flags in an application.
  • Filter: a rule for evaluating the state of a feature flag.

Private Endpoints

Private endpoints can be used for Azure App Configuration to allow clients on a virtual network (VNet) to securely access data over a private link. Network traffic between the clients on the VNet and the App Configuration store traverses over the VNet using a private link on the Microsoft backbone network, eliminating exposure to the public internet.
