This article mainly introduces "what are the ways to realize the server load balancing technology". In the daily operation, I believe that many people have doubts about the way to realize the server load balancing technology. The editor consulted all kinds of materials and sorted out the simple and useful operation methods. I hope it will be helpful for you to answer the doubts about "what are the ways to realize the server load balancing technology?" Next, please follow the editor to study!

1. Http redirect protocol to achieve load balancing.

According to the user's http request, a real web server address is calculated, and the web server address is written into the http redirection response and returned to the browser, which is revisited by the browser. This method is relatively simple, but the performance is poor.

2. [protocol layer] dns domain name resolution load balancer

Configure records of multiple domain names corresponding to IP on the DNS server. This method directly hands over the work of load balancing to DNS, which saves a lot of trouble for website management and maintenance, has fast access speed, and effectively improves performance.

3. [protocol layer] reverse proxy load balancing

While providing load balancing function, the reverse proxy server manages a group of web servers. According to the load balancing algorithm, the requested browser access is forwarded to different web servers for processing, and the processing results are returned to the browser through the reverse server. This method is simple to deploy, but the web server address can not be directly exposed, and there is no need to use external IP address. As a communication bridge, reverse proxy service needs to configure two network cards and two sets of external and internal IP addresses.

4. [network layer] IP load balancer

Load balancing is carried out at the network layer by modifying the destination address. This method is faster than reverse server load balancing in response to requests, but slows down when the request data is large (large videos or files).

5. [link layer] data link layer load balancing

The Mac address is modified in the data link layer for load balancing, and the IP of the load balancing server is the same as the virtual IP of the web service group it manages. It does not need the address translation of the load balancing server, but it requires high bandwidth of the network card of the load balancing server.

6. F5

F5, whose full name is F5-BIG-IP-GTM, is the most popular hardware load balancing device with a concurrency capability of one million. This method can achieve load balancing and redundancy of multiple links, can access multiple ISP links, and achieve load balancing and high availability between links.

At this point, the study of "what are the ways to achieve server load balancing technology" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
