AWS r53recovery documentation change
Summary
Updated terminology from 'EC2 Auto Scaling' to 'EC2 Amazon EC2 Auto Scaling' throughout the document for consistency, including headings, parameter names, and links. No functional changes to the process or security requirements.
Security assessment
The changes are purely editorial, standardizing terminology to include redundant 'Amazon EC2' branding. There are no modifications to security guidance, vulnerability fixes, or new security features. The existing IAM policy reference remains unchanged in substance.
