Which solution will meet these requirements with the MOST operational efficiency?
Create a new AWS Cost and Usage Report. Search the report for cost recommendations for the EC2 instances the Auto Scaling group, and the EBS volumes.
Create new Amazon CloudWatch billing alerts. Check the alert statuses for cost recommendations for the EC2 instances, the Auto Scaling group, and the EBS volumes.
Configure AWS Compute Optimizer for cost recommendations for the EC2 instances, the Auto Scaling group and the EBS volumes.
Configure AWS Compute Optimizer for cost recommendations for the EC2 instances. Create a new AWS Cost and Usage Report. Search the report for cost recommendations for the Auto Scaling group and the EBS volumes.
Explanations:
While the AWS Cost and Usage Report provides detailed insights into usage and costs, it does not provide specific cost optimization recommendations for EC2 instances, Auto Scaling groups, or EBS volumes. This option requires manual searching and analysis, leading to less operational efficiency.
Amazon CloudWatch billing alerts help monitor costs but do not provide specific cost optimization recommendations. This approach involves checking alert statuses manually, which is less efficient than an automated solution.
AWS Compute Optimizer analyzes resource utilization and provides recommendations for cost optimization for EC2 instances, Auto Scaling groups, and EBS volumes. This option automates the process, delivering insights with minimal operational overhead.
While AWS Compute Optimizer offers recommendations for EC2 instances, the AWS Cost and Usage Report alone does not provide targeted recommendations for the Auto Scaling group and EBS volumes. This combination does not fully utilize AWS tools for maximizing operational efficiency.
I rank that the answer is:
Configure AWS Compute Optimizer for cost recommendations for the EC2 instances, the Auto Scaling group and the EBS volumes.
