Exam CLO-002 topic 1 question 35 discussion

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/

he correct answer is C. Right-sizing. Explanation: • Right-sizing refers to the process of adjusting the resources allocated to a system or application to match the actual workload demands. This involves decreasing or increasing resources to ensure that you’re not over-provisioning (which would result in paying for unused capacity) or under-provisioning (which could lead to performance issues).

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.

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.
