Question 1 of 30
A company is running a web application on AWS that experiences variable traffic patterns throughout the day. The application is currently hosted on an EC2 instance with 4 vCPUs and 16 GB of RAM. During peak hours, the instance is often at 80% CPU utilization, while during off-peak hours, it drops to around 20%. The company wants to optimize costs by right-sizing their resources. If the average CPU utilization during peak hours is 80% and during off-peak hours is 20%, what would be the most effective right-sizing strategy to ensure that the application runs efficiently while minimizing costs?
Implement an Auto Scaling group to dynamically adjust the number of instances based on traffic patterns.
Upgrade the EC2 instance to a larger instance type with more vCPUs and RAM.
Downgrade the EC2 instance to a smaller instance type to save costs during off-peak hours.
Keep the current instance size and monitor performance for a longer period before making changes.
