What is AWS Parameter Store used for?

AWS Systems Manager Parameter Store is primarily used for securely storing configuration data and secrets. This service allows you to manage and retrieve important information such as API keys, database connection strings, and other sensitive configuration settings in a centralized and secure manner.

Parameter Store provides multiple options for storing parameters, including plain text and encrypted (using AWS Key Management Service), preventing unauthorized access and ensuring that sensitive data is managed according to best practices for security and compliance.

Furthermore, Parameter Store integrates well with various AWS services, enabling applications and services to easily retrieve parameters programmatically. This helps in keeping configurations consistent and ensuring that sensitive data is not hardcoded into applications, thus improving security by reducing the risk of exposure.

In contrast, the other choices do not accurately represent the intended use of Parameter Store or pertain more broadly to AWS functionalities that are better served by different services.
