Question

A SysOps administrator manages 200 EBS gp2 volumes attached to production EC2 instances. CloudWatch metrics show the volumes consistently operate well below their baseline IOPS, and the finance team wants to reduce storage costs without impacting the online (attached) workloads. What is the MOST cost-effective action the administrator should take?

Accepted Answer

Migrate the volumes from gp2 to gp3, which offers up to 20% lower per-GB cost and lets you provision IOPS/throughput independently, using in-place modification with no detach required

Answer

Take snapshots of all gp2 volumes, delete the originals, and restore them as sc1 cold HDD volumes to lower storage cost

Answer

Detach each gp2 volume, convert it to an io2 volume, and reattach it to gain higher durability at a lower price

Answer

Enable EBS fast snapshot restore on all gp2 volumes to reduce the ongoing storage charges
