B
EC2 with FTP server using Amazon EBS, AWS Batch for job queues, and EventBridge for nightly job invocation and file deletion.
C
AWS Transfer Family with FTP server on EBS, AWS Batch for job queues, and S3 notifications for triggering AWS Batch jobs and file deletion upon arrival.
D
AWS Transfer Family with FTP server in S3 Standard, a Lambda function for processing and auto-deletion, and S3 notifications to invoke the function as files arrive.
