Load Balancing – The Online Traffic Police

    load balancing

    Have you ever wondered how many people are accessing the internet throughout the day? Millions! But then don’t you feel that the servers which are responsible for providing information on the internet are susceptible to breakdowns? Of course, they are.

    So many people are trying to get their hands on similar data. But then, why does it not? That is because the web world has traffic police too! Well, of course, no, they are not the uniformed traffic police with whistles that we have in our real world, but their role is similar to them, though. They are the ones responsible for load balancing in the internet world. What is it? Let’s take a more detailed look at it.

    What is load balancing?

    In order to understand what load balancing is, you need to first understand what traffic is in the web world. It has pretty much a similar meaning in the web world, as in the real world. It refers to the number of people who visit a particular website. 

    But there are some sites that experience the flow of thousands (if not more) of users on their website asking for concurrent searches. Then how does the website deliver the services? This is exactly where the concept of load balancing comes into play. A load balancer is a software that is set up just in front of the servers and control the search requests that come that way. 

    This a cost-effective way to meet the demands of the users without having then to set up more servers. The load balancing router also makes it easier to secure the information as there is a lesser number of servers to be supervised. 

    What is the function of a load balancer?

    As we now have an idea of what a load balancer is, let us take a more in-depth look at the different functions that a load balancer performs. Below mentioned are some of the fundamental functions that a load balancing router performs. 

    1. A load balancer distributes the requests of the users across the various servers efficiently. This distributes the network load properly and does not lead to a breakdown of the system.

    2. The load balancer sends signals to the servers which are online and available so that the users get reliable and authentic information only. 

    3. The system of load balancing routers also calls for a pretty flexible system, by increasing the scalability of the same. 

    Different load balancing techniques have different benefits and functions, though. Some algorithms will distribute search requests evenly across online servers, some will direct the search to the server which provides the fastest response, some will select the server depending on the IP address of the user.  

    How does load balancing work?

    Load balancing is a way to control the incoming traffic on a site. But how does it control the same? Does it keep track of every person who visits the website? Sounds a bit strenuous, even impossible right? So of course, there is a much easier way of dealing with the same. Let see then.

    1. First, the user enters the information they are looking for in their browser.

    2. The search enters the web world and immediately is faced with load balancing software.

    3. This load balancing software analyses which server is available and online and sends the search request to the server according to the set algorithm.

    4. The server then retrieves the information that has been asked for from the database and sends it to the user via the same route.

    What are the benefits of using a load balancer?

    The traffic on the road affects everyone on the road. Similarly, the traffic of a website affects everyone who is involved in the system. Therefore, a load balancer does not only make it easier for the website owners but also for the users. What are the merits of using a load balancer then? Here are some of them listed below.

    1. Firstly, a load balancing software looks after the entire system of the internet and sees to the fact that it does not break down.

    2. It also reduces expenses as a lesser number of servers can be used. The load balancer can and will direct the searches of the users accordingly. 

    3. It increases the scalability of the system and helps to cater to the needs of the users no matter how dynamic they are. 

    A load balancing software makes the entire system of searching for a particular thing easier and more efficient. It does not make the users wait, nor the websites fail to provide the information required from them.
