Which service offers secure storage for configuration and secrets management?

The selected service, AWS Systems Manager Parameter Store, provides a secure way to store configuration data and secrets. It is designed to help manage sensitive data such as passwords, database strings, and configuration settings in a secure manner. Parameter Store offers encryption at rest and in transit, ensuring that data is not exposed. It also allows fine-grained access control through AWS Identity and Access Management (IAM), making it easier to govern who can access specific configurations and secrets.

This service integrates well with other AWS services and can be used in various scenarios, such as retrieving configuration data for applications deployed across different environments. The ease of use and security features make it a suitable choice for managing sensitive information securely.

In contrast, while AWS Secrets Manager is also used for managing secrets, the question specifically emphasizes configuration and secrets management. AWS Key Management Service focuses on managing cryptographic keys, and AWS Config is more about resource configurations and compliance tracking rather than storing secrets. Thus, Systems Manager Parameter Store is the most fitting option for the requirements laid out in the question.
