Node.js Clustering: Don't Let Black Friday Bury Your Server
Picture this: Black Friday midnight sale launches, 30k users slam your Node.js server, and poof—it's dead. Clustering turns that nightmare into a breeze, but only if you do it right.
⚡ Key Takeaways
- Node.js clustering uses all CPU cores to handle traffic spikes like Black Friday without crashing.
- Graceful shutdown enables zero-downtime deploys by draining one worker at a time.
- Self-healing respawns keep your app alive even if individual workers fail under load.
