tomcat：

is a core project of the Apache Software Foundation's Jakarta project;

It was developed by Apache, Sun and some other companies and individuals;

Tomcat Server is a free and open source** web application server;

It is a lightweight application server;

It is commonly used in small and medium-sized systems and when there are not many concurrent access users;

Actually, Tomcat is partly an extension of the Apache server, but it runs independently;

So when you run tomcat, it's actually running as a separate process from apache.
