How Reuters Replaced WebSockets with Amazon Cognito and SQS

The advantages of a serverless architecture are, at this point, not really a matter of debate. The question for every application or component becomes, “How can I avoid having to manage servers?” Sometimes you come across a roadblock: Perhaps you need a GPU; it takes 60 seconds just to load a machine learning model; maybe your task takes longer than the 300 seconds Amazon gives you for a Lambda process and you can’t figure out how to chop it up. The excuses never end.

Perhaps you want to push events into a browser or app through a WebSocket to create something similar to a chat or email application. You could use Nginx and Redis to create topics and have applications subscribe to them via a push stream; however, that means managing some long-running processes and servers. You can fake it and pound your backend once a second, butBut Amazon SQS and Cognito offer an easier way. Each user session can be paired with a Cognito identity and an SQS queue meaning applications can use SQS long-polling to receive events in real-time. At Reuters, we use this in production to support messaging in event-driven web applications and have open-sourced the underlying Serverless stack.
