For a straight web site, I'm sure any of these are fine if not "pricey". What do you folks use for web service hosting? Sure, it can be just a web host like any other. But Heroku (last time I checked) does not support any form of long-polling and/or streaming for instance.

I can setup a VPS with nginx proxying to tornado/node.js/etc that does streaming without a problem. However, there's the issue of scaling it out that's pain. You can use Linode's API or something similar but eek, what a mess.

Thoughts?
