Apache Tomcat is a widely used open-source application server that serves as a Java Servlet and JavaServer Pages (JSP) container. It is known for its simplicity, flexibility, and scalability. Here are some common use cases for Apache Tomcat:
Web application hosting, Java EE web profile applications, Java Server Pages (JSP) development, servlet development, Java API for WebSocket (JSR-356) support, spring framework applications, RESTful web services, development and testing environments, small to medium-sized applications, and high availability (with load balancers).
Here are some popular alternatives to Apache Tomcat:
Jetty
WildFly (formerly JBoss)
GlassFish

Here are some key distinctions between Apache Tomcat and other application servers:
Modularity and Lightweight Nature:
Tomcat is known for its lightweight and modular design. It is specifically designed to be a servlet container, providing the essential components needed for servlet and JSP execution. This lightweight nature makes it well-suited for simpler applications and scenarios where a minimalistic approach is preferred.
Embeddability:
Tomcat is easily embeddable in other applications. Developers can embed Tomcat within their Java applications, allowing them to run servlets and JSP without the need for a separate server installation.
Focus on Web Applications:
Tomcat has a strong focus on serving web applications, especially those developed using Java technologies like servlets and JSP. It is widely used as a standalone server for hosting web applications.
Configuration and Extensibility:
Tomcat’s configuration is typically done through XML files, and it is known for its straightforward configuration. It is extensible through the addition of custom components and configurations.
