Today, I will talk to you about the ways of load balancing, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Several ways of load balancing are as follows:

(1) HTTP redirect load balancer

The advantage of this load balancing scheme is that it is relatively simple, but the disadvantage is that the browser needs to request the server twice each time to complete one access, so the performance is poor.

(2) DNS domain name resolution load balancer

The advantage of DNS domain name resolution load balancer is that it leaves the load balancing work to DNS, omitting the trouble of network management, and the disadvantage is that DNS may cache A records and is not controlled by the website.

(3) reverse proxy load balancing

The advantage is that the deployment is simple, and the disadvantage is that the reverse proxy server is the transit station for all requests and responses, and its performance may become a bottleneck.

(4) IP load balancing

The advantage is that IP load balancer completes data distribution in the kernel process, which has better processing performance than reverse proxy balancer. The disadvantage is that the network card bandwidth of load balancing has become the bottleneck of the system.

(5) data link layer load balancing

To avoid the bottleneck of the network card bandwidth of the load balancing server is the most widely used load balancing method for large websites at present.

After reading the above, do you have any further understanding of the way of load balancing? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
