1 causeRecently, a stress test was conducted on the newly developed web system, and it was found that the response speed of concurrent logon home pages under tomcat's default configuration pressure to 600 people was severely affected, more than 2000 errors of 500 and 502 occur in one round. I made a look at the logon time statistics and printed out the total server processing time. I saw that some responses were indeed within 20 seconds, however, the average time is far different from that teste

The common advantage of R-proxy and mod_jk is that only Apache can be deployed on the public network, saving public IP Address resources.
Apache can handle static web pages through settings, so Tomcat can handle dynamic requests such as JSP and servlet.
The common disadvantage is that if the front-end Apache proxy server stops running, all cluster services cannot be provided externally.

Before using Nginx did the Web reverse proxy, did not do load balancing, today there is a classmate need to do Tomcat load balancing, I also studied.

Recently looking at a book on Javaweb implementation of the Web site distributed architecture, it mentions that through load balancing, you can avoid issues such as server paralysis caused by massive access or the inability of users to access due to a single server failure.
