You might have heard the word “load balancing” several times but what do you think is that? The term defines the idea of dividing the work load equally among others when one person is unable to handle it. Similarly when we talk about web hosting it refers to distributing the load on single server to other server when a single server can’t handle it. When you click or type a web address you are routed through a host server to view the page. This means a load balancer spreads the “work” of running a website across multiple servers in order to ensure that the servers hosting the site aren’t overloaded.
