Which cloud concept is demonstrated by using AWS Compute Optimizer?

AWS Compute Optimizer is a service that analyzes the configuration and utilization metrics of your AWS resources to recommend optimal configurations. Its primary goal is to help you identify over-provisioned or under-provisioned resources, such as Amazon EC2 instances, Amazon EBS volumes, and AWS Lambda functions. By providing recommendations for the most appropriate resource size and type based on actual usage data, Compute Optimizer directly enables the practice of rightsizing. Rightsizing is the process of matching workload requirements to the most cost-effective and performant resource, which is the core function of this service.

A. Security validation involves assessing resources against security best practices and standards, a function performed by services like AWS Security Hub and Amazon Inspector.

C. Elasticity is the ability to automatically scale resources up and down to meet demand, which is primarily managed by services like AWS Auto Scaling.

D. Global reach refers to the ability to deploy applications across AWS's worldwide infrastructure of Regions and Availability Zones, a fundamental characteristic of the platform itself.

1. AWS Compute Optimizer User Guide: In the "What is AWS Compute Optimizer?" section

the documentation states

"AWS Compute Optimizer recommends optimal AWS resources for your workloads to reduce costs and improve performance... To get started

you opt in to Compute Optimizer. It then begins analyzing the AWS resources in your account." The guide includes specific sections on "Rightsizing recommendations for EC2 instances."

2. AWS Well-Architected Framework

Cost Optimization Pillar (Whitepaper): This official whitepaper defines rightsizing in the section "COST 4 - Right size workloads." It states

"Right sizing is the process of matching instance types and sizes to your workload performance and capacity requirements at the lowest possible cost." It later recommends using tools like AWS Compute Optimizer to implement this practice.

3. AWS Documentation - Rightsizing recommendations: The official AWS documentation for Cost Management has a dedicated page on this topic

which states

"AWS offers several tools that you can use to right-size your resources. You can use AWS Cost Explorer

Amazon CloudWatch

and AWS Compute Optimizer."
