Policy: AWS > Well-Architected Tool > AWS Well-Architected Framework > Performance Efficiency > PERF 02. How do you select your compute solution? > Re-evaluate compute needs based on metrics

Use system-level metrics to identify the behavior and requirements of your workload over time. Evaluate your workload's needs by comparing the available resources with these requirements and make changes to your compute environment to best match your workload's profile. For example, over time a system might be observed to be more memory-intensive than initially thought, so moving to a different instance family or size could improve both performance and efficiency.

See Re-evaluate compute needs based on metrics for more information.
