> Theoretical development costs seem like they'd be much lower on platforms where you expect lower error rates. Then again, that theoretical becomes quite practical when your app that runs on EC2 breaks down because it isn't as scalable as you thought it might be. Google has already thought about the tough questions like "what happens if an entire datacenter goes offline?" and GAE has that designed in. Developing for failure doesn't make sense when you're operating on a small scale, but it makes a lot of sense when you do need to scale. I'd rather take a bit of a development hit up front when there are few users than take the hit when a site really gains traction.
