Description:

This talk will introduce the concept of Flux, a unidirectional data flow pattern proposed by Facebook, to implement better client side web applications; and how we took this pattern to the server side to implement realtime, scalable microservices. This talk will take you through our adventurous journey in rewriting a monolithic Waartaa into several microservices and how we implemented:

• Inter process communication
• Keeping services as stateless as possible
• Single source of truth
• Realtime publishers

The end result of this venture is ircb, a scalable IRB bouncer for humans, written using Python 3 asyncio, and on top of homebrewed zeromq based store.

The talk will be organized as:

• Setting the scene
• Why move to microservices?
• Managing state in microservices can be a nightmare?
• Server side Flux to the rescue
• Walk through IRCB architecture
• Demo - concepts in action
• Future
• Questions
