What is a Load Balancer?
A load balancer is an application or hardware-based reverse proxy that distributes traffic across multiple servers. Load balancers aim to ensure that no single server gets overwhelmed by requests.

More About Load Balancers
If you use cloud hosting or a Virtual Private Server (VPS), your website might be hosted across multiple servers. When a visitor tries to access your site, a load balancer routes that connection to the server that can best handle it.
Load balancers are essential for websites that receive high amounts of traffic. A load balancer acts as a reverse proxy that takes incoming requests and forwards them to web servers. The goal of a load balancer is for no single server to receive more requests than it can handle. That way, you ensure that your website offers the best possible performance even when under stress.
