This article mainly explains "what is nginx load balancing". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what nginx load balancing is.

Most of the time, we are used to putting a whole set of programs on one server, which is no problem in the early stage of the project and saves costs. However, with the development of the project and the increase in the number of data and users, the load of a single server will not be able to bear, and it will also affect the operation of the whole program, resulting in slow user access cards. At this time, we can increase the number of servers and use nginx reverse proxy and load balancing to co-ordinate the server cluster to break through the bottleneck of a single server.

Nginx reverse proxy

Nginx reverse proxy is the source server of the agent program that communicates with the outside world. The server that the user accesses is actually the proxy server, not the source server of the program. The process of communication is that the user visits the proxy server, and the proxy server organizes the user's request and forwards it to the source server. The source server receives the request and responds, and the proxy server returns the response to the user.

Nginx load balancing

Nginx load balancing means that after the nginx server receives the requests, it distributes the requests to different servers, which can greatly reduce the load of a single server and improve the efficiency of the program.

So when we find that the number of visits to the website is increasing, but the access speed is gradually slower, and the program response is also slower. You can check whether the deployment of a server department of the business is all handled by a single server, and whether the load of the server is in a dangerous position.

At the same time, the use of nginx reverse proxy and load balancing can effectively improve the server's response speed and an upper limit of the number of visits, but also effectively hide the IP of the source server to avoid exposure.

Thank you for your reading. the above is the content of "what is nginx load balancer". After the study of this article, I believe you have a deeper understanding of what nginx load balancer is, and the specific usage needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
