Messaging architecture at Facebook
The audience will learn design options for building large scale messaging system and how technical, philosophical and organizational considerations surrounding these played out at Facebook.
Building a scalable messaging backend for a Billion user is Hard. This talk covers the initial design days when the Facebook messaging architecture was being decided.
Should back-end stores be eventually or strongly consistent? How much availability is highly available? Should we build services or components? How big does a piece of software have to be before it stops being a component. How can a back-end be built for an application that's yet to be designed? Is it possible to simulate a billion user workload - and does it help?
The issues faced by the design team ranged from the technical to the philosophical - to ultimately the practical. This talk will explore some of these areas.
Given the limited time - it would not be possible to introduce background material. A grasp of scalable key value stores, CAP theorem and eventual consistency, reliable storage systems would be useful in getting more out of the talk.
