Right-sizing involves adjusting the resources allocated to a system or application to closely match its actual usage needs. This process ensures that resources are optimized, avoiding over-provisioning, and therefore, minimizing the cost of unused capacity while maintaining performance. It is a continuous and deliberate approach to reallocate resources efficiently, which best describes the concept of reducing resources to avoid paying for unused capacity.
Right sizing is the most effective way to control cloud costs. It involves continually analyzing instance performance and usage needs and patterns—and then turning off idle instances and right sizing instances that are either overprovisioned or poorly matched to the workload. https://aws.amazon.com/aws-cost-management/aws-cost-optimization/right-sizing/
Auto-scaling fits best, according to the cloud essentials book: Right-sizing is the process of evaluating current on-premises servers for need and sizing before moving to the cloud. Autoscaling is sizing resources in the cloud.

Auto-scaling differs from right-sizing. Auto-scaling is a dynamic process that operates within defined performance thresholds. Right-sizing is a manual process that more closely aligns a virtual machine instance’s specifications to its workload.
Right-sizing involves adjusting the resources allocated to a system or application to match its actual usage needs. By rightsizing, organizations can optimize their resource allocation and avoid over-provisioning, which leads to paying for unused capacity. This optimization ensures that resources are allocated efficiently, balancing performance requirements with cost considerations.
