Automated Trading with IB and Amazon EC2

I took Interactive Brokers (IB) account for trading in NSE (India) around 18 months back. My idea was to use IB API and make an automated trading system to run small scalping and market making programs. IB is probably the only one offering API trading for NSE in India. I made a scalping program using IB Java API and was running it from my MacBook. I am not sure, if you know that a MacBook can sometimes behave like a powerful server.
