Explanation
AWS Systems Manager Patch Manager is the correct solution because:
- Automated Patching: Patch Manager automates the process of patching managed instances across multiple AWS services (EC2, Lightsail) and hybrid environments (on-premises servers)
- Least Operational Effort: Once configured, Patch Manager runs automatically without manual intervention, requiring minimal ongoing operational effort
- Cross-Platform Support: Supports Windows and Linux operating systems
- Centralized Management: Provides a single interface to manage patching across the entire environment
Why other options are incorrect:
- AWS Shield: A DDoS protection service, not designed for OS/application patching
- Manual RDP connections: High operational effort, not automated, and doesn't scale
- Amazon GuardDuty: A threat detection service that monitors for malicious activity, not a patching solution
Patch Manager allows you to scan instances for missing patches and apply them according to predefined maintenance windows, making it the most efficient solution for automated security updates.
