If you'are looking for hosting some Python in the cloud, let me introduce you to http://python-cloud.com/
This PaaS platform can automatically scale up and down your application regarding your traffic. You can also finely customize if you want vertical, horizontal or both types of scalability. The consequence of this scaling is that you pay as you go: you only pay for your real consumption and not the potential one. Deployment via git. Non AWS, hosted in tier-4+ datacenters. Free trial!
