Serving 10,000 Live Users on a Single 4-Core Server: The Go Way (No Redis, No K8s!) ✨
Ever feel like every chat about “scaling” immediately goes off the rails, spiraling into a giant wishlist of distributed databases, message queues, and all those fancy container orchestration platforms? It’s easy, right? To get totally swept up in this idea that a ton of users always means you need massive, complicated infrastructure. But, what if I told you we’re actually handling a bustling crowd of 10,000 live, concurrent users on just one humble 4-core server? And get this: we’re doing it without even touching Redis for caching or Kubernetes for orchestration. Mind blown, right? 🤯
I know, I know. It sounds almost too good to be true, doesn’t it? In this little chat, I want to pull back the curtain and share our whole journey. We’ll dig into the snag we hit, the core idea that got us unstuck, and all those nitty-gritty Golang implementation bits that turned this seemingly impossible dream into reality. So, get ready to maybe, just maybe, rethink some of your scaling assumptions and discover the surprising punch of smart, lean engineering.
The Problem with “Defaulting to Distributed” 🚧
You know, in our crazy fast dev world today, the instant reaction to needing more scale is often just to throw more machines, more…
