Amazon EC2 Systems Manager provides capabilities that enable automated configuration and ongoing management of systems at scale across Windows and Linux workloads running in Amazon EC2 or on-premises at no additional charge. It offers components like Run Command, State Manager, Inventory, Maintenance Windows, Patch Manager, Automation, and Parameter Store to remotely manage servers, define consistent configurations, gather inventory, schedule maintenance windows, automate patching, simplify deployments, and securely store parameters. Using these capabilities is expected to reduce the total cost of ownership for hybrid and cloud environments compared to traditional management tools.
