What change should be made to alleviate the performance problem?

A SysOps administrator is responsible for a legacy. CPU-heavy application. The application can only be scaled vertically Currently, the application is deployed on a single t2 large Amazon EC2 instance The system is showing 90% CPU usage and significant performance latency after a few minutes

What change should be made to alleviate the performance problem?
A . Change the Amazon EBS volume to Provisioned lOPs
B . Upgrade to a compute-optimized instance
C . Add additional t3. large instances to the application
D . Purchase Reserved Instances

Answer: B

Explanation:

To address the performance issues of a CPU-heavy application running on a t2.large EC2 instance, the best course of action is to upgrade to a compute-optimized instance. Compute-optimized instances provide a higher ratio of CPU resources compared to memory, making them ideal for applications that require high CPU performance.

Upgrade to a Compute-Optimized Instance:

Identify a suitable compute-optimized instance type, such as the c5.large, which offers better CPU performance compared to the t2.large.

Stop the current EC2 instance and change the instance type to the chosen compute-optimized instance.

Reference: Amazon EC2 Instance Types

Considerations:

Ensure that the new instance type is compatible with the existing AMI and EBS volume configuration.

Monitor the application performance after the upgrade to ensure that the new instance type meets the application’s requirements.

This approach directly addresses the high CPU utilization and performance latency issues.
