Load balancing allows us to distribute incoming network traffic across multiple servers resulting in high availability and reliability.

Load balancing is a technique used to distribute incoming network traffic across multiple servers in a way that ensures high availability and reliability. The goal of load balancing is to maximize the use of available resources, ensure that no single server is overwhelmed by too much traffic, and maintain high levels of performance for the end users.

With the growth of the Internet, modern websites are often required to handle millions of concurrent requests from users. To meet this high demand, it is necessary to scale the infrastructure horizontally, which involves adding more servers to the network. This approach allows the website to handle large volumes of traffic in the most efficient manner.

A load balancer acts as a traffic controller in such networks, and sits in front of the servers. The load balancer receives incoming client requests and then routes them to one of the available servers. This way, the load balancer distributes the incoming traffic across multiple servers, ensuring that no single server is overwhelmed by too much traffic.

The load balancer continuously monitors the health of the servers, and in the event that a server goes down, it will redirect incoming traffic to the remaining online servers. This ensures that the end-users are not impacted by any single server failure and that the website remains highly available and reliable.

Additionally, when a new server is added to the network, the load balancer will automatically start sending requests to it without any manual intervention. This makes it easy to scale the infrastructure as needed and ensures that the load balancer is always distributing traffic to the available servers in the most efficient manner.

In conclusion, load balancing is a critical component of modern computing that helps websites handle large volumes of traffic in a highly available and reliable manner. The goal of load balancing is to maximize the use of available resources, prevent any single server from being overwhelmed, and maintain high levels of performance for end-users.
