Load balancing web server

What is a server? It is something that manages network resources and serves clients who are connected to it. In other words, it is a computer that is designated for supplying information in many forms, so that other computers can use it. Now there may be several requests from hundreds, even thousands of clients in a big network. And all requests are coming in at the same time. So it is not unlikely that the server gets over burdened and is thus unable to serve anyone properly. 2 things can happen in such a scenario. #1 - the responses to all actions of a client is delayed. And #2 - the server is unable to serve the client at all.

It is much like a busy street on peak hour. Everyone wanting to go at the same time and thus no one being able to do so. So what do the traffic department do? It diverts traffic to avoid snarl-ups. The same is the case with a busy server. It takes the help of a 'load balancing web server' to ease the flow.

So the goal of a load balancing web server is to distribute incoming requests among a bunch of web servers in order to increase response time and throughput.

Advantages

• It eliminates downtime by automatically redirecting traffic in the event of server failure or network congestion.
• Improves website or application speed by distributing the load among multiple servers, maximizing reliability, responsiveness and throughput for a better customer experience..
• The organization can easily expand to meet increased demand by adding servers, without having to change the necessary configuration or take the existing servers down for an upgrade..

There is a popular saying - "2 heads are always better than 1". It is something like this. You are actually taking stock of the situation and leveraging the power of more to serve one, so that the network is able to function efficiently.
