Compare AWS Config vs. AWS Systems Manager

AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With Config, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines. This enables you to simplify compliance auditing, security analysis, change management, and operational troubleshooting.

AWS Systems Manager is a management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems. These capabilities help you define and track system configurations, prevent drift, and maintain software compliance of your EC2 and on-premises configurations. By providing a management approach that is designed for the scale and agility of the cloud but extends into your on-premises data center, Systems Manager makes it easier for you to seamlessly bridge your existing infrastructure with AWS.

Systems Manager is easy to use. Simply access Systems Manager from the EC2 Management Console, select the instances you want to manage, and define the management tasks you want to perform. Systems Manager is available now at no cost to manage both your EC2 and on-premises resources.
