Question

A CloudOps engineer manages a data-processing EC2 instance using a 500 GiB gp2 EBS volume. During nightly batch jobs, CloudWatch shows VolumeQueueLength consistently above 10 and VolumeReadOps saturating, causing job delays. The application requires higher throughput but not more storage capacity, and the team wants to minimize cost while allowing throughput to be tuned independently of volume size. Which action best resolves the bottleneck?

Accepted Answer

Migrate the volume to gp3 and provision the required IOPS and throughput independently of the volume size.

Answer

Increase the gp2 volume size to 1,000 GiB to raise the baseline IOPS allocation.

Answer

Migrate the volume to a Cold HDD (sc1) volume to lower cost while increasing throughput.

Answer

Enable EBS-optimized instance settings and attach an additional gp2 volume in a RAID 0 array.
