especially when the reasoning is that of costs. S3 IA may cost more when accessing, but still better than outbound traffic costs for EC2 and EBS…perhaps someone could give a sample comparison of costs ?
I agree with Phbardwaj. One requirement was that the solution should be scalable. Well… a single EC2 instance + EBS volumes doesn’t scale very well… Wheres S3-IA does… I guess "the lowest possible AWS cost" outweighs scalability in this case.
