AWS AWSEC2 documentation change
Summary
Restructured EBS optimization documentation with added prerequisites, warnings about instance store data loss, and updated CLI/PowerShell commands
Security assessment
While the change adds warnings about data loss when stopping instances, this is standard operational guidance rather than addressing a specific security vulnerability
