Question

A media company runs a CPU-bound video transcoding service on a fleet of EC2 instances behind an Auto Scaling group. The workload is Linux-based, compiled from open-source code, and consistently drives sustained high CPU utilization with minimal memory usage. The engineering team wants to maximize price-performance and reduce compute cost without sacrificing throughput. Which change should the solutions architect recommend?

Accepted Answer

Migrate the fleet to compute-optimized instances powered by AWS Graviton processors (e.g., C7g) after recompiling the application for the Arm64 architecture.

Answer

Migrate the fleet to memory-optimized instances (e.g., R7i) to provide more headroom for the transcoding workload.

Answer

Move the fleet to burstable general-purpose instances (e.g., T3) and rely on CPU credits to handle transcoding spikes.

Answer

Attach additional gp3 EBS volumes with maximum provisioned IOPS to accelerate the transcoding throughput.
