1. The difference between Nginx and tomcat

Nginx is often used as a static content service and proxy server, and foreign requests are directly forwarded to the following application servers (tomcat,Django, etc.). Tomcat is more often used as an application container to soak java web app in it.

Strictly speaking, Apache and nginx should be called HTTP Server, while tomcat is an Application Server that is a container for Servlet/JSO applications.

The client accesses the resources stored on the server (HTML files, picture files, etc.) through HTTP Server. HTTP Server just transmits the files on the server to the client truthfully through HTTP protocol.

The application server often runs behind the HTTP Server, executes the application, converts the dynamic content into static content, and distributes it to the client through HTTP Server.

Note: nginx only distributes the request and does not process it!

2. The difference between nginx and Apache

Apache is a synchronous multi-process model, one connection corresponds to one process, while nginx is one step, and multiple connections (ten thousand levels) can correspond to one process.

Nginx lightweight, anti-concurrency, good handling of static files

Apache is super stable and supports comparative checklist for PHP. Nginx needs to be used with other backends, so it has advantages to handle dynamic requests.

It is recommended to use front-end nginx for anti-concurrency and back-end apache clusters for better cooperation.
