MAX: Realtime messaging and activity stream engine

What if I told you that we’ve built an open source “WhatsApp”-like RESTful API on the top of Pyramid? We’ve developed MAX: a real-time messaging service and activity stream that has become the key feature for a social intranet at the BarcelonaTech University

We will show how we designed and built MAX with performance in mind using state of the art Python technologies like Gevent, WSGI, and multi-threaded queue processing. We will also show you how we’ve managed to design a simple architecture guaranteeing both high scalability and performance, achieving connecting ratios over 30.000 students, teachers, and university staff.

The API is secured using oAuth 2.0 resource owner password credentials flow powered by our own oAuth server implementation (Osiris) also Pyramid-based. We are using MongoDB as general storage backend and RabbitMQ over websockets to support realtime and messaging.
