A solutions architect needs to advise a company on how to migrate its on-premises data processing application to the AWS Cloud. Currently, users upload input files through a web portal. The web server then stores the uploaded files on NAS and messages the processing server over a message queue. Each media file can take up to 1 hour to process. The company has determined that the number of media files awaiting processing is significantly higher during business hours, with the number of files rapidly declining after business hours. What is the MOST cost-effective migration recommendation?

Chose D1
The better version of Option A would have been the use of Lambda Durable functions which was introduced in Re:Invent 2025 in conjunction with SQS Queues
Chose D2
A. Lambda functions cannot handle 1-hour processing task (max 15 min timeout) B. Amazon MQ more complex and expensive than SQS. Single EC2 instance per task is less efficient than scaling based on queue length. C. Again Lambda cannot handle 1 hour jobs.
