Please use this post as a landing page to get you started with using the EC2 Simple Systems Manager services from Amazon Web Services. Simple Systems Manager or (SSM) is a set of services used to manage EC2 instances as well as on-premises machines (known as managed instances) with the SSM agent installed on them. You can use these services to maintain state, run ad-hoc commands, and configure patch compliance among other things.
