Question

A company’s application is having performance issues. The application is stateful and needs to complete in-memory tasks on Amazon EC2 instances. The company used AWS CloudFormation to deploy infrastructure and used the M5 EC2 instance family. As traffic increased, the application performance degraded. Users are reporting delays when the users attempt to access the application. Which solution will resolve these issues in the MOST operationally efficient way?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Modify the CloudFormation templates. Replace the EC2 instances with R5 EC2 instances. Deploy the Amazon CloudWatch agent on the EC2 instances to generate custom application latency metrics for future capacity planning. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon CloudWatch collects metrics, logs and alarms to monitor and react to operational health. AWS CloudFormation provisions infrastructure as code repeatably.
