I've been using WebSockets on production in a large scale system for almost a decade. In this session I am going to share variety of challenges I've personally dealt with and some of the ways on how to overcome them. If you'd like to know how to design application that can take advantages of WebSockets when you have a microservices and APIs based back-end, that's the talk you've been looking for!

Topic includes:
- What are WebSockets?
