Python Server in AWS

I have written some Web services in Python.I want to deploy it in AWS, I have created the instance. I tried to run using putty and it was coming up well using the command python Flo.py, which starts the server 0.0.0.0:8080. But the problem is when I close the putty window the server is terminating. How i can start a server in 8080 just like httpd?
