Storage
CoreAmazon EBS
Explicit performance metrics, volume optimization, snapshots, and EC2 storage.
Key points
- EBS operations require correlation of volume IOPS, throughput, latency, queue, instance bandwidth, and snapshots.
Best-known use cases
- D1.3, D2.3, and D3.2: tune or recover the named EC2 block volume from measured performance or recovery evidence.
What candidates often confuse it with
- EBS provides block storage for EC2; EFS and FSx provide shared file systems and S3 provides object storage.
Key takeaway
Before changing an EBS family, prove whether the volume, instance bandwidth, workload pattern, or recovery state is limiting.
