The solution will receive batches of large image files, resize the files, and store the files in an Amazon S3 bucket for up to 6 months. The solution must handle significant variance in demand. The solution must also be reliable at enterprise scale and have the ability to rerun processing jobs in the event of failure. Which solution will meet these requirements MOST cost-effectively?
