AWS AppConfig
Deploy application configurations with confidence
Overview
AWS AppConfig, a capability of AWS Systems Manager, allows you to create, manage, and quickly deploy application configurations. AppConfig supports controlled deployments to applications of any size and includes built-in validation checks and monitoring. You can use AppConfig to roll out application configuration changes, just as you do with code, but without the need to deploy new code.
✨ Key Features
- Feature flags and toggles
- Dynamic application configuration
- Configuration validation
- Controlled deployment strategies (e.g., canary, linear)
- Automatic rollback on errors
- Integration with AWS Lambda, ECS, EC2, and mobile apps
- Freeform configuration data (JSON, YAML, text)
🎯 Key Differentiators
- Native integration with the AWS ecosystem
- Pay-as-you-go pricing model can be more cost-effective than per-seat pricing of competitors
- Includes validation and safe deployment strategies as built-in features
Unique Value: Enables developers and DevOps engineers to release application features more quickly and safely by separating configuration changes from code deployments.
🎯 Use Cases (4)
✅ Best For
- A mobile app team gradually rolls out a new UI to its user base, starting with 1% and increasing over time.
- An e-commerce site changes its promotional banner by updating a configuration in AppConfig, without a code deployment.
- A development team uses a validator to ensure that a new configuration value is a valid JSON before it can be deployed.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Storing sensitive data or secrets (better suited for AWS Secrets Manager or Parameter Store)
- Managing infrastructure configuration (better suited for CloudFormation or Terraform)
🏆 Alternatives
While third-party tools like LaunchDarkly offer more advanced features for user targeting and experimentation, AWS AppConfig provides a robust, cost-effective, and natively integrated solution for core feature flagging and configuration deployment on AWS.
