AWS autoscaling documentation change
Summary
Updated documentation to consistently use 'Amazon EC2 Auto Scaling' instead of 'Auto Scaling' throughout the file for branding consistency
Security assessment
The changes are purely terminological updates to align with branding standards (adding 'Amazon EC2' prefix to 'Auto Scaling'). No security-related content was added, modified, or removed. The existing security considerations around instance replacement patterns and scale-in protection remain unchanged.

Amazon EC2 Auto Scaling will usually replace instances one at a time, with a pause between replacements. However, if the specified maximum instance lifetime doesn't provide enough time to replace each instance individually, Amazon EC2 Auto Scaling must replace more than one instance at a time. Several instances might be replaced at once, by up to 10 percent of the current capacity of your Auto Scaling group. To avoid replacing too many instances at once, either set a longer maximum instance lifetime or use instance scale-in protection to temporarily prevent individual instances from being terminated.
