In cost optimization, which action directly aligns resource capacity with actual demand?

• A. Over-provisioning
• B. Auto-scaling to peak load
• C. Right-sizing resources to match usage
• D. Maintaining fixed capacity

Answer: (C)

Aligning resource capacity with the actual demand is essential for cost optimization. Right-sizing resources to match usage means adjusting compute, memory, and other allocations to reflect what is truly needed, so you pay only for what you actually use while still meeting performance needs. This directly reduces waste from idle capacity and avoids paying for over-provisioned resources. Over-provisioning deliberately allocates more than necessary, leading to higher costs and unused capacity. Auto-scaling to peak load can still incur high costs if you keep enough capacity for the peak, even when demand is low. Maintaining fixed capacity lacks responsiveness and often results in paying for unused resources during low-demand periods or throttling during spikes.
