Have you ever played a game of balancing blocks on top of each other? Think of each block as a computer server that works together to make a website or an application work. Sometimes, when a lot of people try to use the website or application at the same time, it can become slow or even break down, just like how the tower of blocks might topple over if you add too many blocks on one side.
Cloud load balancing is like having a grown-up help you balance the blocks. Instead of just one person trying to keep the tower from falling, many people work together to keep the tower balanced. When there are too many people using the website or application, the load balancer helps to distribute the work evenly across the different computer servers, so that no single server becomes overloaded and the website stays fast and stable for everyone to use.
It's like having a teacher give each student in a class a turn to answer a question, so that no one student is doing all the work. The load balancer continually checks on the servers to make sure they're balanced, just like how a teacher might walk around the class to make sure everyone is participating. This helps ensure that the website or application stays running smoothly, even when a lot of people are using it at the same time.
