AWS Secrets Manager and Parameter Store are both AWS services for managing sensitive information, but they serve slightly different purposes:
AWS Secrets Manager is tailored for securely storing and automatically rotating secrets like API keys, database credentials, and tokens. It provides built-in secret rotation, cross-region replication, and fine-grained access control. It’s ideal for managing highly sensitive credentials requiring regular rotation.
AWS Parameter Store (part of Systems Manager) is a more general configuration management service. It stores plain text or encrypted parameters and supports hierarchical organization. While it can manage secrets, it doesn't have built-in rotation and is more cost-effective for general configuration data.
Use Secrets Manager for critical secrets with rotation needs, and Parameter Store for broader configuration management.
