AWS SSM Documents and Run Command for System Automation

Managing servers individually is inefficient and prone to errors. To maintain security, consistency, and speed, modern cloud administrators rely on automated orchestration to manage fleets of instances at scale. This text-based course guides you through AWS Systems Manager (SSM) with a focus on Run Command and SSM Documents, enabling you to automate routine maintenance and software deployments without opening SSH or RDP ports. You will start with foundational concepts, understanding how the SSM Agent communicates and how IAM roles secure your infrastructure. Next, you will explore writing custom SSM Documents in both JSON and YAML, and executing them securely across hybrid fleets. You will also learn modern cloud practices, including how to integrate these automation tasks into CI/CD pipelines and track execution state with basic observability tools. What you'll learn: - Understand the core architecture of AWS Systems Manager and agent-based instance management - Configure IAM policies to grant secure, least-privilege access for executing remote commands - Create and version custom SSM Documents using structured JSON and YAML formats - Execute commands across multiple instances simultaneously using target tags and rate control - Implement automated patching and software installation tasks without manual remote access - Integrate SSM automation with basic monitoring and notification workflows to track execution status This course begins with essential terminology and setup requirements before moving into step-by-step configuration and automation scenarios. It is designed for system administrators, cloud engineers, and IT professionals who are new to AWS Systems Manager. No prior experience with SSM is required, though a basic understanding of cloud concepts and command-line interfaces will help you progress quickly.
