What is Load Balancer?

A system that distributes incoming traffic across multiple servers to prevent any one from being overwhelmed

Why It Matters

Load balancers keep your site running smoothly during traffic spikes and improve reliability

Real-World Example

During a sale, a load balancer sends customers to different servers so no single one crashes

“Understanding terms like Load Balancer matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
