I found today http://modulus.io, they use different clouds. But definitly at a better price as dotcloud/nodejitsu/heroku, especially for smaller projects with SSL. Nice are the backend statistics without paying for any extra service.

But i think in the next months many new PaaS services will rise, thanks to docker ;-)

And i hope many new without amazon (amazon is not bad, but expensive).

I don't think it's too far off.
