If you already have load balancing in mind, it means your traffic has really grown. Congrats on that!
If you are getting into the topic, here you have the 4 things you have to know about load balancing. It’s a good starting point for you to go deeper!
What is load balancing?
In a nutshell, load balancing is the action of efficiently distributing traffic and workload across different servers. The more available servers, the best chance to distribute the loads and not let a single one get overwhelmed.
There are different load balancers, simple and more sophisticated mechanisms, software, or hardware. Basically, load balancers constantly check servers to be sure they can handle the incoming requests without trouble. Based on this, they distribute the loads as needed.
