# Systems Manager Parameter

Systems Manager Parameter in AWS is a resource that stores configuration data and secrets in a secure, hierarchical way. It allows you to manage values such as database strings, passwords, or license codes, and retrieve them programmatically or through the AWS Management Console. Parameters can be plain text, encrypted with AWS KMS, or organized with naming conventions for easier management. This helps centralize configuration, improve security, and simplify automation across AWS services and applications.
