Hussein Nasser has a slick new course out for backend engineers looking to build scalable, real-time applications. The course focuses on the tricky design challenges of creating systems that need constant, two-way communication, like chat apps or online games. It's all built around the widely-supported WebSockets protocol.
You'll start with a deep dive into how WebSockets works under the hood, then learn how to scale it up for massive traffic using various proxies. To cap it off, you'll put your new skills to the test by designing both a chat system and a game from the ground up.
