AWS AppConfig
AWS AppConfig is a fully managed service to manage and deploy configuration data securely and dynamically across your applications without requiring you to redeploy the entire service.
It allows you to create, manage, and deploy configuration changes separately from your application code, making it easy to update configurations without interrupting application availability.
1. Old Way of Configuration Changes
In the traditional approach, configuration changes were typically handled using hard-coded configurations, static configuration files, or inline configurations within application code. When updates were needed:
- Hard-coded configuration files or static files stored in the application needed to be modified.
- Re-deployment of the entire application was required to implement small configuration changes.
- This led to frequent deployments, longer development cycles, downtime, and manual error-prone processes in production environments.
2. AWS AppConfig provides the following key benefits
- Decouples Configuration Data from the application code, allowing you to manage configurations independently.
- Supports deployment strategies like blue-green, canary, and rollback, helping to minimize risk and downtime by allowing incremental updates.
- Supports versioning of configurations, enabling you to test changes in one environment and easily roll back if needed.
- Integrates seamlessly with AWS Lambda, ECS, EC2, and EventBridge, facilitating automated and scalable configuration management across various environments.
- Support Real-Time Monitoring using Amazon EventBridge, which allows you to trigger workflows based on configuration event
