What is a load balancer

#What is a load balancer?

Load balancer is a term related to servers. With this load balancer, even if the website is accessed centrally or the server fails, stable services can continue to be provided to the users who are visiting. .

What is load?

When accessing various servers on the Internet, you can use resources such as CPU and memory installed in the server to process instructions and send them to the user's computer, and the instruction content is displayed on the browser.

When the number of visits is small and the number of processing is small, there will generally be no problem. However, when access is concentrated for any reason, the browser will become very stuck. This is actually a high load status.

How the load balancer works

The built-in load balancer is placed between the Internet and various servers. Set the IP address of the load balancer setting to Virtual IP addresses, when web access is made, are assigned to the appropriate web server, and requests to the load balancer transfer the data to the various actual servers. Specifically, it is sent to the IP addresses assigned to various servers. It can then be automatically distributed to several servers and the load can be distributed.

The role and function of load balancer

At present, the speed of the website is very important, but as the number of visits increases, it is necessary for us to take measures to prevent Page speed is reduced. A load balancer is composed of multiple servers. Even if one server fails, it can automatically switch to another server to continue access.
