Azure App Configuration
Overview
App Configuration helps developers manage application settings (key/value pairs) and control feature availability (feature toggling). It aims to simplify many of the tasks of working with complex configuration data.
App Configuration supports:
- Hierarchical namespaces (Not Hierarchical RBAC)
- Labelling
- Extensive queries
- Batch retrieval
- Specialized management operations
- A feature-management user interface

Access to App Configuration is either by Access key or RBAC with the App Configuration Data Owner and App Configuration Data Reader roles.
