This article introduces the knowledge about "what is the difference between Tomcat and Apache/Nginx". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to handle these situations! I hope you can read carefully and learn something!

What is the difference between Tomcat and Apache?

Tomcat has a common name for this role: Web Container. Similar Web containers include Jetty, Resin, etc.

Why are they called containers?

Because in the software world, this kind of management of the whole life cycle of things is called containers. Tomcat here is responsible for the entire Servlet life cycle (LifeCycle), including when to create Servlets, when to initialize some internal resources, what methods to execute when processing requests, when to destroy, etc. Like a parent. So, you'll often hear that Spring's Ioc is implemented through an Ioc container, because it's also managing the entire Spring Bean lifecycle.

Looking back, what does Apache do?

Apache is also known as a web server. This kind of brother, they can only handle HTTP protocol, for example, when we request static resources such as HTML, images, etc., we can complete it through Web servers. But if the request is JSP,PHP, etc., these times, the Web server is unable to, can only forward the request to the appropriate person to handle, if the request JSP or Servlet, then this appropriate person is the above Web container. Similar Web servers are Apache, IIS, Nginx, etc.

So, to sum up, the difference between the two is that Tomcat can not only be used to handle dynamic resources, Servlet, JSP, but also static resources, while Apache can only handle static resources. What is the difference between Web Container and Web Server? I believe you already know the answer.

At this time, you will definitely say, Tomcat this kid can do it all, what do you want Apache for?

Sigh, this kid learned quite a lot at that time, and they were all very good, but he didn't learn particularly well in dealing with static resources. It was like saying that a tailor might be able to cook his own food, but he was not as professional as a chef.

Therefore, when processing static resources, you can configure a Web Server such as Apache in front of Tomcat, which can not only efficiently process static resources, but also cache these commonly used static resources, and even achieve the purpose of Load Balancer (of course, this also requires the latter Web Container to be clustered).

"What is the difference between Tomcat and Apache/Nginx" is introduced here, thank you for reading. If you want to know more about industry-related knowledge, you can pay attention to the website. Xiaobian will output more high-quality practical articles for everyone!
