Ask HN: Any cloud computing instances cheaper than AWS EC2 Micro?

If you don't have server sided scripts you wouldn't need a virtual root server in the first place, but rather host your pages at github, wordpress or the likes. If you do have active components you could go to Google App Engine, Heroku or PythonAnywhere. If you do need a virtual root server, it's hard to beat a t1.micro, especially if you don't need it 24/7.

You can try appfog(paas).. and if you are coding on nodejs, you can try nodejitsu(paas).

google app engine - free.

App Engine is definitely not free. One of my very small apps used to exceed front-end quota and caused me a bill.
