Apache Tomcat, often referred to as Tomcat Server, is an open-source Java Servlet Container developed by the Apache Software Foundation. Tomcat implements several Java EE specifications including Java Servlet, JavaServer Pages (JSP), Java EL, and WebSocket, and provides a "pure Java" HTTP web server environment in which Java code can run.

XenApp is application virtualization software produced by Citrix Systems that allows Windows applications to be accessed via individual devices from a shared server or cloud system.

XenDesktop is a desktop virtualization software platform that allows multiple users to access and run Microsoft Windows desktops that are installed at a centralized location separate from the devices from which they are being accessed.

MySQL is an open source Relational Database Management System (RDBMS) based on Structured Query Language (SQL).
