EC2 was innovation, but many people didn’t see it. S3 was more distinctly new although still not the first object store or even object store over HTTP as a service, but if you were there a LOT of people did not share that perception and said it cost too much, would never scale, or required too much software to be modified. I’m not saying that to diminish the importance of S3 but simply that we often wildly overstate the importance of being first to ship an idea versus easy to work with, low-drama for operations, etc.
