The following gives you an overview of forward proxy, reverse proxy and load balancing, hoping to give you some help in practical application. Load balancing involves a lot of things, there are not many theories, and there are many books on the Internet. today, we will use the accumulated experience in the industry to make an answer.

1. What is a forward agent?

The forward agent occurs on the client side, which is perceived by the user and initiated by the user.

For example: × × ×.

We cannot access the external network, but we can access the proxy cloud server, and then the proxy server helps us get data from the external network. However, before using it, users often need to actively configure the agent on the client side.

* in order to hide your identity, a forward proxy is used.

two。 What is a reverse proxy?

The reverse proxy occurs on the server side and is unaware of the proxy from the user's point of view (this is known only to the server engineer).

For example:

When the user accesses server A, server A returns data to the user.

But there is no data on server A, it secretly takes the data from server B and then returns it to the user.

This process takes place on the server side and is not known to the user (only the server operators know about it).

3. What is load balancing?

Load balancing is an application of reverse proxy.

The client accesses the server, and the server distributes the requests to many other different servers (that is, reverse proxies), thus reducing the pressure on a single server to handle massive requests without crashing.

It takes a reverse proxy to achieve load balancing. Load balancing is one of the purposes of reverse proxy.

Reverse proxy is the ability to forward requests. This is the basis.

Load balancing, which forwards requests to different servers to balance each server

After reading the above overview of forward proxy, reverse proxy and load balancing, if you have anything else you need to know, you can find out what you are interested in in the industry information or find our professional and technical engineer to answer it. Technical engineers have more than ten years of experience in the industry.
