What would be really nice to see would be tools to make it easy to migrate between these cloud platforms. The nice thing about making an old-school apache-served website is that you know if your host does wrong by you, you can just move. In many cases, the moving process is simply ordering service, uploading your files, and pointing your domain to the new host.

I realize that this is mainly just the difference between newer technology and decades of standardization, but until cloud providers reach that point, the prospect of bad/missing support is really frightening.
