Summary

Updated terminology from 'Auto Scaling group' to 'Amazon EC2 Auto Scaling group' for consistency and clarity. Fixed blog post title reference.

Security assessment

Changes involve branding updates and terminology consistency rather than addressing security vulnerabilities or documenting security features. No security implications identified in the context of scaling mechanisms.
