AWS ebs documentation change
Summary
Updated documentation about volume initialization process, added details about Provisioned Rate for Volume Initialization, and restructured console steps.
Security assessment
The changes focus on performance optimization during volume initialization (e.g., introducing Provisioned Rate for Volume Initialization) and clarify operational steps. No explicit security vulnerabilities, encryption changes, or access control updates are mentioned. The encryption section remains unchanged except for link corrections.
