Expand description

Amazon Web Services Systems Manager is a collection of capabilities that helps you automate management tasks such as collecting system inventory, applying operating system (OS) patches, automating the creation of Amazon Machine Images (AMIs), and configuring operating systems (OSs) and applications at scale. Systems Manager lets you remotely and securely manage the configuration of your managed nodes. A managed node is any Amazon Elastic Compute Cloud (Amazon EC2) instance, edge device, or on-premises server or virtual machine (VM) that has been configured for Systems Manager.

With support for IoT Greengrass core devices, the phrase managed instance has been changed to managed node in most of the Systems Manager documentation. The Systems Manager console, API calls, error messages, and SSM documents still use the term instance.

This reference is intended to be used with the Amazon Web Services Systems Manager User Guide.

To get started, verify prerequisites and configure managed nodes. For more information, see Setting up Amazon Web Services Systems Manager in the Amazon Web Services Systems Manager User Guide.
