Question 4

Your application on EC2 creates images thumbnails after profile photos are uploaded to Amazon S3. These thumbnails can be easily recreated, and only need to be kept for 45 days. The source images should be able to be immediately retrieved for these 45 days, and afterwards, the user can wait up to 6 hours. How would you design this?

Answer 4

• S3 source images can be on STANDARD, with a lifecycle
configuration to transition them to GLACIER after 45 days.
• S3 thumbnails can be on ONEZONE_IA, with a lifecycle
configuration to expire them (delete them) after 45 days.
