SSM stands for Systems Manager, which is a service provided by Amazon Web Services (AWS) that helps to manage and automate infrastructure deployment and configuration. SSM provides a unified user interface that can be used to manage multiple AWS resources such as EC2 instances, on-premises servers, and virtual machines.
SSM enables users to perform tasks such as software patching, compliance auditing, and remote management of instances without having to log in or establish SSH connections to each instance individually. It also offers features like Run Command, State Manager, Inventory Management, Parameter Store, Maintenance Windows and Patch Manager which can help in automating operational tasks.
Overall, SSM simplifies the management of hybrid cloud environments and provides an efficient way of managing resources at scale.
