When a website or business application is under strain, one server can no longer handle the entire load. Organizations use "load balancing" to spread the load across multiple servers. This prevents one server from becoming overwhelmed, which can lead to it slowing down, dropping requests, or even crash. Load balancing allows you to evenly distribute network traffic in order to avoid overloading any resource. This strategy improves performance and availability of websites, applications, databases, and other computing resources. It helps users process their requests quickly and accurately. Load balancing is an invisible facilitator between a client's computer and a group servers. It ensures that connection requests are not lost. Applications, websites, databases, online services, and other services that depend on load balancing would most likely fail if there was too much demand.
