Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 130 discussion

AWS Compute Optimize helps analyze the usage patterns of AWS resources, such as EC2 instances and Auto Scaling groups, and makes recommendations on how to optimize them for performance and cost using machine learning algorithms.It then generates recommendations that can be used to adjust instance types, purchase options, and other parameters.It provides two types of recommendations: Recommended instance types - recommends instance types that are more cost-effective and better suited to the workload requirements. Recommended purchase options - recommends purchasing options, such as Reserved Instances or Savings Plans, that can help customers save money on their compute resources.

C. Install the Amazon CloudWatch agent on each of the EC2 instances. Turn on AWS Compute Optimizer, and let it run for at least 12 hours. Review the recommendations from Compute Optimizer, and rightsize the EC2 instances as directed.

A - Not possible D - Costliest Option possible now between B and C The question mentions high-memory EC2 instances. You cannot get memory metrics without the Cloudwatch agent installed hence C.

Option C is most cost effective choice.

C is incorrect : When you first opt in Compute Optimizer, it may take up to 24 hours to fully analyze the AWS resources in your account. https://aws.amazon.com/compute-optimizer/faqs/

Option A is not in the running because it will require incurring further expense to address the cost issue. Option D is expensive - the Enterprise Support plan charges a minimum flat fee minimum or a % of your AWS bill. This could be a large amount for the company's hundreds of instances. Option B is expensive - Detailed monitoring scales based on the number of metrics and the number of resources. The company has hundreds of instances so this option could potentially be more expensive than D. Option C - Compute Optimizer will provide improvement suggestions based on 14 prior days usage data from the moment it was enabled. Moreover, the default service option is free. Nothing is said about the custom metrics being used for the CloudWatch agent but it could be the most expensive of all options if mis-used. So either cost 0 or incredibly large if used carelessly.

C. need CW agent for RAm util

C- Compute Optimizer is the easiest solution

C - cost optimizer

C is correct - Optimzer

Option C may be a good solution to rightsize the EC2 instances but may incur additional cost for installing the Amazon CloudWatch agent on each of the EC2 instances. The MOST cost-effective solution to analyze the company’s Amazon EC2 instances and Amazon EBS volumes is to create a dashboard using AWS Systems Manager OpsCenter. The OpsCenter dashboard can be configured to visualize the Amazon CloudWatch metrics associated with the EC2 instances and their EBS volumes. By reviewing the dashboard periodically, usage patterns can be identified, and EC2 instances can be right-sized based on the peaks in the metrics.

The correct answer is C. Installing the Amazon CloudWatch agent on each of the EC2 instances and turning on AWS Compute Optimizer allows the solutions architect to analyze the environment and make recommendations on the sizing of the EC2 instances in a cost-effective way. AWS Compute Optimizer analyzes the utilization of the instances and recommends the optimal instance types for the workloads. This solution is more cost-effective than creating a dashboard and reviewing it periodically, or signing up for the AWS Enterprise Support plan and waiting for Trusted Advisor recommendations.

C is correct, with computer optimizer
