SSM Parameter Store Overview
Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management and secrets management.

You can store values as plain text or encrypted data.
You can reference Systems Manager parameters in your scripts, commands, SSM documents, and configuration and automation workflows by using the unique name that you specified when you created the parameter.

Labels can help you remember the purpose of a parameter version when there are multiple versions.
