If you’re looking to run a business website for 365 days, well, you need to balance the load your web infrastructure is taking for you.
In this case, load balancing will help your organization maintain a flawless web infrastructure.
It will help your developers in distributing the network load between various interface cards. This will also help you in dispersing the load. Moreover, it will improve the website’s responsiveness.
Well, now let us look at what a load balancer is.
A load balancer is the interconnecting thing present between the server and the client. It will help you decrease the load that your application receives in the form of traffic.
How? Let’s find it out.
Basically, the load balancer accepts your incoming network along with the traffic your website and application are generating.
Now the balancer will distribute it across multiple servers so that there’s no load on a single server.
There are various open-source load balancers present in the market today that will help you take offload from your server.
