In the times of today, the world wide web is the backbone of society and industry. More and more people are shifting their businesses online and dependability on the world wide web is seen more today than ever today. Covid-19, the pandemic has also caused an adverse surge in this growing rate of internet users by making it the need of businesses to shift online for their survival. Hence, all the stated facts result in overcrowded internet traffic. Even before the pandemic, the world wide web had gained a prominent place in the society without which normal life is unable to function. Therefore, managing and responding to such an enhanced amount of internet users concurrently causes some delays. For example, the social media platforms witnessing a surge of millions of users each day requires managing requests of an enormous number of users all at the same time. Traditional website development techniques fail to handle these concurrent requests on their own. Hence, Load Balancers come to the aid.
Load Balancers distribute the user requests over a network to a pool of shared computing resources. Load Balancer supports a large pool of servers on the back-end that serve the site’s content. When a request is received from the user, the Load Balancer routes it to the back-end servers, thereby equally distributing the requests among the pool of servers. Here in this article, we discuss the top 5 best performing Load Balancers ensuring better and improved site performance and reliability.
