00:00Have you ever shopped during big billion days or else Diwali sales and wondered with

00:09crores of people shopping at once, how does that website not crashed? You know,

00:13behind the scenes it's the power of something called as load balancer. In this

00:19video we are going to explore how load balancing works in real life and yeah

00:24let's implement that using Java. Now imagine you're at a shopping mall and

00:28there is just only one billing counter now picture thousand people trying to

00:33check out there you know from the same billing counter you know it's very

00:36hectic right but what if there are 10 billing counters and there is a friendly

00:41manager who is guiding each person to the next available counter that manager is

00:48your load balancer. In the backend load balancer sits between the user and

00:53multiple servers means you know for example user will be sending a request

00:57that request will be handled by the load balancer that load balancer will

01:02distribute that request to next available servers means there will be

01:07multiple servers will be there user will be sending a request that request will be

01:11hand over to the respective server from the load balancer. When a user opens your

01:16site the load balancer decides which server will handle that users request in

01:21order to make that happen there are a lot of algorithms are there like round robin is

01:26there least connections IP hash like that. Today we will try to implement round robin

01:32load balancing using Java you know in round robin algorithm each incoming requests

01:38will be handled by the next available server in order. Want to watch full video

01:43comment amazon will directly DM you the link and follow us more for interesting such videos thank you
