Amazon Systems Manager document

An AWS Systems Manager document (SSM document) defines the actions that Systems Manager performs on your managed instances. Systems Manager includes more than 100 pre-configured documents that you can use by specifying parameters at runtime. Pre-configured documents can be found in the Systems Manager Documents console by choosing the Owned by Amazon tab, or by specifying Amazon for the Owner filter when calling the ListDocuments API operation. Documents use JavaScript Object Notation (JSON) or YAML, and they include steps and parameters that you specify.
