AWS autoscaling documentation change

Service: autoscaling · 2025-11-22 · Documentation low

File: autoscaling/ec2/userguide/ts-as-instancelaunchfailure.md

Summary

Updated terminology from 'Auto Scaling group' to 'Amazon EC2 Auto Scaling group' throughout the document for consistency and full service name accuracy

Security assessment

The changes are purely terminological updates to use the full service name ('Amazon EC2 Auto Scaling group') rather than the abbreviated form. There is no evidence of security vulnerability fixes, security incident references, or new security guidance. The modifications maintain existing security-related content (like key policy configurations) but only update naming conventions.
