As strain increases on a website or business application, eventually, a single server cannot support the full workload. To meet demand, organizations spread the workload over multiple servers called "load balancing", this practice prevents a single server from becoming overworked, which could cause it to slow down, drop requests, and even crash. Load balancing lets you evenly distribute network traffic to prevent failure caused by overloading a particular resource. This strategy improves the performance and availability of applications, websites, databases, and other computing resources. It also helps process user requests quickly and accurately. From a user perspective, load balancing acts as an invisible facilitator that sits between a client and a group of servers, ensuring connection requests don’t get lost. Without load balancing, applications, websites, databases, and online services would likely fail when demand gets too high.
