A company has an application. Once a month, the application creates a compressed file that contains every object within an Amazon S3 bucket. The total size of the objects before compression is 1 TB. The application runs by using a scheduled cron job on an Amazon EC2 instance that has a 5 TB Amazon Elastic Block Store (Amazon EBS) volume attached. The application downloads all the files from the source S3 bucket to the EBS volume, compresses the file, and uploads the file to a target S3 bucket. Every invocation of the application takes 2 hours from start to finish. Which combination of actions should a solutions architect take to OPTIMIZE costs for this application? (Choose two.)
