AWS ebs documentation change
Summary
Updated gp3 volume specifications (max IOPS, throughput, size) and added tip recommending io2 Block Express for latency-sensitive workloads
Security assessment
The changes document performance improvements and feature updates for EBS volumes but contain no security-related context or vulnerability fixes.
