Overview
Managed identities (e.g., Azure Managed Identities, AWS IAM Roles for EC2) solve the problem of 'secret management' for applications. Instead of storing a password or API key in a configuration file, the cloud provider automatically provides the identity to the resource.
How it Works
The cloud provider manages the lifecycle of the credentials (rotation, storage) and makes them available to the application via a local metadata service. The application then uses these credentials to get an access token for other services.
Benefits
- Improved Security: No credentials stored in code or configuration files.
- Reduced Overhead: No need to manually rotate or manage secrets.
- Ease of Use: Simplifies the process of connecting cloud services securely.
