                AWS Systems Manager is the operations hub for your AWS applications and resources and a secure end-to-end management solution.
                The program's primary functionalities include creating a maintenance window, creating a document, sending a command to a document,
                listing documents, listing commands, creating an OpsItem, modifying an OpsItem, and deleting AWS SSM resources.
                Upon completion of the program, all AWS resources are cleaned up.
