I've yet to see an SLA, issued by any company, that would actually compensate the organization for anything resembling their true losses. It simply isn't possible to do that without jacking up the costs to an unbearable level. SLA/SLGs are really only about rebating the lost services, not the lost revenue. You get 1 day of your expenses back, but not 1 day of profit. As for building from the ground up, I think you've been asleep for the past few years, and I find that most smaller companies are more willing and able to build from the ground up. Big companies go buy it from Oracle, etc., small companies build it themselves. My experience is that in the time it'd take to make a big commercial package do what I need, I can build it from scratch. This is true in many areas, but most especially so in web applications. There'll be PHP, Python, Ruby and other bindings (Java for the Enterprisey), and it'll work just great. I’ve written before about why SLAs are useless.

However they are not ready for prime time. Their Service Level guarantees look like a joke. But the main problem for Amazon based deployments is absence of appropriate tools and frameworks. Yes, it is acceptable for a big company like Amazon to build apps ground up from very low database level. But the small/mid sized companies the Amazon obviously targets this might be an overkill.
