Infinitely scalable chat

nelsonic commented 8 years ago

Last month @tanzim introduced you to AWS Lambda ... this time we're going to show you how to build a chat/messenger app that scales to _hundreds of thousands of messages per second_ without deploying a single Docker Container or manage a Database.

Overview

Instead of using a (traditional) Node.js Web Server, we'll be using Lambda Functions. (Don't worry, its still node.js...)
Instead of a (traditional) Database, DynamoDB.
Instead of Pub/Sub and Socket.IO we will use AWS SNS
If there's time we can also show how to do Facebook/Twitter/Google Auth using AWS Cognito

We will be writing the code for the app over the next couple of weekends. It will be similar to our previous demo app: https://github.com/dwyl/hapi-socketio-redis-chat-example in that there will be _end-to-end tests_ and _detailed documentation_, but that's where the similarity ends!

During the talk we will do a full stack/code/deployment walkthrough (aprox 15 mins) and then do AMA/Q&A (5 mins)

We already have extensive practical notes on using AWS Lambda: https://github.com/dwyl/learn-aws-lambda ... these are going to be expanded into an end-to-end tutorial which everyone can follow.

If you are curious about the future of web apps, give us a thumbs up.
