Apache Tomcat vs Caddy: What are the differences?

# Apache Tomcat vs Caddy

Apache Tomcat and Caddy are both web servers, but they differ in various key aspects. Below are the key differences between Apache Tomcat and Caddy:

1. **Purpose:** Apache Tomcat is a traditional Java-based web server and servlet container, commonly used for hosting Java web applications. In contrast, Caddy is a modern, lightweight web server that focuses on ease of configuration, automatic HTTPS setup, and rapid deployment of static websites.
   
2. **Configuration:** Apache Tomcat relies on complex XML-based configuration files for setting up and managing server settings, which can be cumbersome for beginners. Whereas Caddy uses a simple and intuitive configuration file syntax, making it easier to specify server configurations and automate tasks.
   
3. **HTTPS Support:** Apache Tomcat requires manual configuration and management of SSL certificates for enabling HTTPS on websites. On the other hand, Caddy encrypts connections by default and automatically configures HTTPS using Let's Encrypt, simplifying the setup process for secure communication.
   
4. **Performance:** Apache Tomcat is known for its robustness and scalability, making it suitable for handling high traffic and complex web applications. Meanwhile, Caddy emphasizes performance optimization, utilizing features like HTTP/2 support, automatic HTTP/2 Server Push, and efficient resource management for faster loading times.
   
5. **Extensions and Plugins:** Apache Tomcat has a wide range of third-party extensions and plugins available through the Apache community, allowing for customizations and additional functionalities. Caddy, on the other hand, comes with built-in support for various plugins and modules, reducing the need for external dependencies and simplifying the server setup process.
   
6. **Community and Support:** Apache Tomcat has a large and active community of developers and users, providing comprehensive documentation, forums, and resources for troubleshooting and assistance. While Caddy has a growing community, its support network may not be as extensive as that of Apache Tomcat.

In Summary, Apache Tomcat and Caddy differ in their purpose, configuration complexity, HTTPS support, performance focus, plugin availability, and community support.

Advice on Apache Tomcat, Caddy

Hari

Needs advice

I was in a situation where I have to configure 40 RHEL servers 20 each for Apache HTTP Server and Tomcat server. My task was to

  1. configure LVM with required logical volumes, format and mount for HTTP and Tomcat servers accordingly.
  2. Install apache and tomcat.
  3. Generate and apply selfsigned certs to http server.
  4. Modify default ports on Tomcat to different ports.
  5. Create users on RHEL for application support team.
  6. other administrative tasks like, start, stop and restart HTTP and Tomcat services.

I have utilized the power of ansible for all these tasks, which made it easy and manageable.
