What is Apache Tomcat?

Apache Tomcat is an open-source Java Servlet Container developed by the Apache Software Foundation. It provides an environment to deploy, run, and manage Java-based applications.

---

Why Apache Tomcat?

• Java Application Hosting: Designed to run Java Servlets and JSP files.
• Lightweight and Scalable: Provides flexibility for small to large-scale deployments.
• Open Source: Free and supported by an active developer community.
• Integration: Works seamlessly with build tools like Maven and repository managers like Nexus.

Tomcat in Our Project

In this project, Apache Tomcat is used as the primary application container to host and deploy Java-based web applications. It integrates with Maven for build automation and Nexus for artifact management.

Role of Tomcat

1. Hosting Applications:

   • Acts as a web server to host Java applications, ensuring a stable and efficient environment.

2. Integration with CI/CD:

   • Deployed artifacts from Nexus are automatically configured to run on Tomcat, ensuring seamless deployment.

3. Application Management:

   • Provides a user-friendly interface for monitoring, managing, and updating applications.

How Tomcat Fits into the Pipeline

1. Build Phase:

   • Java applications are built using Maven.

2. Artifact Storage:

   • Built artifacts are uploaded to Nexus repositories for version management and storage.

3. Deployment to Tomcat:

   • Artifacts are deployed from Nexus to Tomcat for testing and production.
