Update: agent-based access and operations automation
- Session Manager provides controlled sessions without inbound 22 or 3389, but still requires SSM Agent, an instance role, operator IAM permissions, and outbound access to SSM.
- Run Command executes commands at scale, Automation orchestrates multi-step operations, and Patch Manager uses patch baselines and maintenance windows.
- A managed node does not grant every command; documents, targets, concurrency, error thresholds, and logging remain explicit configuration.
