Misconception: "Just add Nginx and everything is solved." In reality a load balancer only distributes traffic – it won’t speed up a slow DB query.

📷 When all traffic lands on one server it crashes. A load balancer sits in front, decides which server gets each request, and keeps the system alive.

Health checks are the silent hero – they pull unhealthy instances out of rotation automatically.

[Deepak Mandal @Prime__23]

Round Robin is simple but assumes every request is equal. Weighted Least Connections considers server capacity and current load.

Think of a movie theater with one ticket window vs 5 counters. More counters = faster service, but you still need a rule to assign patrons.

Many think “just add Nginx and you’re done”. It only spreads load – it can’t fix slow DB queries or memory leaks.

This setup didn’t happen in one Amazon cart — it was built slowly, piece by piece, while working full-time and figuring things out along the way.Still not “perfect,” but it’s mine.Drop your setup below 👇

Would love to see what you’re building with.

I used to think load balancing simply means:

“Send traffic to multiple servers.”

But while writing about it, I realized the real job is different:

• avoid overloaded servers
• route traffic to healthy instances
• handle traffic spikes
• reduce single-server dependency
