A company runs a batch processing job that takes 2 hours to complete on a single large EC2 instance. The job is CPU-intensive and runs once per day. The company wants to reduce costs without changing the job's duration. What is the most cost-effective approach?

Use a larger instance type to finish the job faster.

Move the job to a different AWS Region with lower prices.

Keep the current instance running 24/7 to be ready for the job.

Use Spot Instances for the batch job.

A company is migrating a legacy application to AWS. The application currently runs on a physical server that is heavily underutilized, with CPU usage averaging 5%. The company wants to reduce costs. What is the most appropriate design principle to apply?

Use a Dedicated Host to maintain control over the physical server.

Right-size the EC2 instance to match the actual CPU and memory requirements.

Move the application to a serverless architecture.

Use the largest available EC2 instance to ensure future growth.
