What is the MOST efficient way of monitoring and managing all service limits in the company’s accounts?
Use Amazon CloudWatch and AWS Lambda to periodically calculate the limits across all linked accounts using AWS Trusted Advisor, provide notifications using Amazon SNS if the limits are close to exceeding the threshold.
Reach out to AWS Support to proactively increase the limits across all accounts. That way, the customer avoids creating and managing infrastructure just to raise the service limits.
Use Amazon CloudWatch and AWS Lambda to periodically calculate the limits across all linked accounts using AWS Trusted Advisor, programmatically increase the limits that are close to exceeding the threshold.
Use Amazon CloudWatch and AWS Lambda to periodically calculate the limits across all linked accounts using AWS Trusted Advisor, and use Amazon SNS for notifications if a limit is close to exceeding the threshold. Ensure that the accounts are using the AWS Business Support plan at a minimum.
Explanations:
While CloudWatch, Lambda, and SNS are valid for monitoring and notifications, AWS Trusted Advisor cannot be used to calculate service limits across all linked accounts.
Proactively increasing limits through AWS Support may resolve immediate issues, but it doesn’t offer a sustainable, automated approach for ongoing management of service limits.
CloudWatch, Lambda, and Trusted Advisor cannot programmatically increase service limits; limits must be raised through support requests or via the console, not automated functions.
This option correctly utilizes CloudWatch, Lambda, and Trusted Advisor for monitoring and notifications. It also ensures that the company is using AWS Business Support, which provides proactive service limit management and faster response times.
I classify that the answer is:
Use Amazon CloudWatch and AWS Lambda to periodically calculate the limits across all linked accounts using AWS Trusted Advisor, and use Amazon SNS for notifications if a limit is close to exceeding the threshold. Ensure that the accounts are using the AWS Business Support plan at a minimum.
