Tomcat and Resin are both Java web servers, the main difference lies in their design and implementation.
Tomcat is an open source project of the Apache Foundation. Its design focuses on being a Servlet container and is usually used in conjunction with the Apache HTTP server to handle dynamic requests. Tomcat can run as a stand-alone container, or it can be deployed on other web servers.
Resin is a commercial web server developed by Caucho Technology, designed with a focus on high performance and scalability. Resin performs well in handling static and dynamic requests, and can support high-concurrency and low-latency access. Unlike Tomcat, Resin does not require Apache or another web server as a front end.
When choosing Tomcat or Resin as the Web server, it is necessary to judge according to the specific needs and project requirements. If you need a flexible, open source Servlet container, you can choose Tomcat; if you need a high-performance and scalable commercial solution, you can consider using Resin.
In my work, I will first conduct research and evaluation based on project requirements and performance requirements, and then choose the most suitable web server for the project based on budget and team capabilities.
