Both LVS and nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.
First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you
fails, lvs will automatically identify the problem, so the system is very stable as a whole.4. No traffic, as mentioned above. Lvs only distributes requests, but the traffic does not go out of it. Therefore, it can be used to distribute some lines. Without traffic, I/O performance of the balancer is not affected by large traffic.5. Basically, it supports all applications. Because lvs works on Layer 4, it can perform operations on almost all applicati
. In addition, various lvs have a complete dual-machine Hot Standby solution, therefore, you don't have to worry about the problem with the balancer itself. If the node fails, lvs will automatically identify the problem, so the system is very stable as a whole.

client, which greatly reduces the data size. generally, the value of gzip_comp_level does not differ much in terms of performance. Set it to 4-5. simply increasing it is meaningless, just a waste of CPU cycles.You can also reduce the file size by using some JavaScript and CSS reduction tools, but these are not very relevant to nginx, so I believe you can get more information through Google.Category: nginx
