Scaling images stored at S3

Before going to use Amazon S3 service, I want to know clearly as to the process of resizing images hosted on S3. My plan is - I want to move original image to S3, when user requests different sizes of thumbnails, I need to resize this and serve the image?

What is the best solution to achieve this? Need I to use EC2 for image processing? In that case it costs more, I think.

Answer 1

Resizing on the fly is slow and expensive, and disk is cheaper than CPU. You're better off pre-building the thumbnails at the time you obtain the image, and then storing them statically in S3 alongside the full images.
