AWS autoscaling documentation change
Summary
Updated terminology from 'Auto Scaling group' to 'Amazon EC2 Auto Scaling group' throughout the document for branding consistency. Changed 'Elastic Load Balancing' link text to 'ELB'. Minor phrasing edits without technical substance changes.
Security assessment
Changes are purely branding/nomenclature updates (adding 'Amazon EC2' to service names) and link text adjustments. No security vulnerabilities, mitigations, or new security features are mentioned. The updates maintain the same technical content about auto-scaling architecture benefits without introducing security context.
