What Web Server Does Confluence Use?

If you’re running Confluence, Atlassian’s popular team collaboration software, you might be wondering which web server it uses. Understanding the web server that powers your Confluence instance is essential for troubleshooting and optimizing performance. In this article, we will explore the web server used by Confluence and provide an overview of its features.

Apache Tomcat: The Default Web Server

Confluence uses Apache Tomcat as its default web server. Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages (JSP), and WebSocket technologies. It provides a robust, secure, and scalable environment for running Java-based applications.

Key features of Apache Tomcat include:

  • Simplicity: Apache Tomcat has a simple configuration and deployment process, making it easy to set up and manage.
  • Compatibility: It is compatible with multiple operating systems such as Windows, Linux, and macOS.
  • Safety: Tomcat has built-in security features to protect your Confluence instance from unauthorized access and attacks.
  • Scalability: It allows you to scale your Confluence installation by adding more resources or clustering multiple instances.

The Connector Architecture

The Connector Architecture in Apache Tomcat plays a crucial role in handling incoming requests from clients and forwarding them to the appropriate components within Confluence. It supports various protocols like HTTP, HTTPS, AJP (Apache JServ Protocol), and more.

The most commonly used connectors are:

  1. HTTP Connector: This connector enables Confluence to handle requests over the HTTP protocol, which is the foundation of the modern web.
  2. HTTPS Connector: The HTTPS connector encrypts the communication between clients and Confluence, ensuring data privacy and security.
  3. AJP Connector: The AJP connector is used for communication between Apache HTTP Server and Tomcat, allowing them to work together efficiently.

Using a Different Web Server

While Apache Tomcat is the default web server for Confluence, it is possible to use a different web server if desired. Atlassian provides documentation on how to configure Confluence with alternative web servers like Nginx, Apache HTTP Server, or IIS (Internet Information Services).

The benefits of using a different web server include:

  • Performance Optimization: Some organizations choose to use a specialized web server to further optimize their Confluence instance’s performance.
  • Integration with Existing Infrastructure: If your organization already uses a specific web server for other applications, using the same server for Confluence can simplify administration and maintenance.
  • Advanced Features: Alternative web servers may offer additional features or modules that can enhance functionality, such as load balancing or caching.

In Conclusion

In conclusion, Confluence uses Apache Tomcat as its default web server. Apache Tomcat provides a reliable and scalable platform for running Java-based applications like Confluence.

However, it’s worth noting that you have the flexibility to use alternative web servers if they better suit your organization’s needs. Whether you stick with Apache Tomcat or opt for another web server, understanding the web server’s features and capabilities will help you optimize your Confluence installation.

So now that you know what web server Confluence uses, you can make informed decisions regarding its configuration, performance, and integration with your existing infrastructure.
