In this blog post I’ll go through an example, in repeatable steps, of how to get up and running with the Tornado chat demo on ActiveState’s public sandbox for Stackato.
ActiveState’s Stackato PaaS (Platform-as-a-Service) is based on VMware’s open-source PaaS, Cloud Foundry, and offers an enterprise PaaS solution that will run on any public cloud, private cloud, laptop or desktop.

In this post I will look at the technology infrastructure behind Summify.com, a website that strives to make our lives easier and helps us deal with the information overload we all experience every time we sit down at our computers. Summify has aggregated over 200 million stories from the web and serves them up on-demand through a series of different mediums. The website uses Tornado to push real-time updates out to the users and they have developed over a dozen backend systems, some of which I will cover in this blog post.
