How do I enable continuous deployment of Node.js applications to Amazon EC2?

Question

I am a node.js developer. I have used Heroku and Joyent's no.de platform before .

For both of these platforms , the deployment used to be simple

git push heroku master ( Heroku )

git push joyent master ( Joyent's node)

The above commands used to do the magic . They enabled me to push the code from my local machine to the cloud server, deploy it and automatically restart the server .

Now I am planning to use Amazon AWS as its more configurable to my needs. How do I setup a similar thing on Amazon EC2 for continuos deployment ?

I am using an Ubuntu AMI.

Is there any tool that help me achieve this ? If there are any resources/tutorials that might help me - please let me know.

Thanks !
