What is Azure App Configuration?
Azure App Configuration is a managed service for centralized configuration management and feature flags. The service separates configuration from code and enables runtime changes without redeployment for modern cloud applications and microservices.
Core Features
- Key-Value Store: Hierarchical configuration values with labels for environments
- Feature Flags: Feature activation by percentage, user group, or schedule, including a dedicated feature management UI
- Key Vault References: Secure referencing of secrets without duplication
- Configuration Snapshots: Versioned snapshots for consistent rollouts
- Event Grid Integration: Push notifications on configuration changes
- Geo-Replication: Optional replication (Standard/Premium tier) for improved resilience and regional failover
Typical Use Cases
Feature Rollouts: Teams gradually enable new features for 1%, 10%, then 100% of users. If issues arise, the feature is immediately disabled without code rollback.
Environment-Specific Configuration: Microservices load configuration from App Configuration at startup. Labels distinguish Development, Staging, and Production.
A/B Testing: Product teams test different variants with different user groups. Feature flags control variant selection while analytics measures results.
Benefits
- Separation of configuration and code for safer deployments
- Immediate changes without redeployment
- Built-in auditing of all configuration changes
- Native integration with Azure services and popular frameworks
- Four-tier pricing model (Free to Premium) for different throughput, storage, and availability needs

Frequently Asked Questions
What is the difference from Azure Key Vault?
Key Vault securely stores secrets and certificates. App Configuration stores application configuration and feature flags. Both are typically combined by having App Configuration reference Key Vault secrets.
How do feature flags work?
Feature flags enable or disable features at runtime. They can be rolled out by percentage, filtered by user groups, or scheduled, without redeployment.
Which SDKs are supported?
Native providers or SDKs are available for .NET, Java/Spring, JavaScript/Node.js, Python, and Go. Other languages can use the REST API directly.
How are changes propagated?
Applications can poll configuration or receive push notifications via Event Grid. Refresh intervals are configurable.
What does Azure App Configuration cost?
There are four tiers: Free (no cost, 1,000 requests/day, no SLA), Developer, Standard, and Premium. Standard and Premium offer unlimited stores per subscription, higher throughput and storage limits, and an SLA. See the official pricing page for details.
