Run an image-encoding workload whose CPU utilization is consistently high.
Prioritize compute capacity over memory capacity when selecting an instance family.
Which choice is most appropriate?
Choose a Compute Optimized EC2 instance family for sustained CPU-intensive processing and validate the workload's measured needs.
Detailed explanation
S3 storage class selection does not change an EC2 instance's CPU capacity.

Foundation review
Family selection
The workload bottleneck should drive the family choice; changing unrelated S3 settings cannot add CPU.
Sustained versus burst
A constant high load differs from a short burst and should not rely on credits alone.
