Serverless Socializing

Serverless Socializing: How I Built a Quick Multi-Player Serverless Game Working with a fully remote team, it's been hard to develop some team camaraderie. To help with this, we played various multiplayer, cloud-based games! And of course, I tried to build my own. In this talk, we'll play the game and understand how it is built with a serverless architecture in mind!
