CI/CD Java Hotstar Demo

End-to-End CI/CD Pipeline for a Java Web Application
Hotstar-inspired UI • Pure Servlet + JSP • Automated from GitHub to Tomcat

A clean, production-like DevOps demonstration that automates the full lifecycle of a simple Java web app: code push → build → quality check → artifact storage → deployment → cloud backup.

Tools & Technologies

Component	Tool	Role / Notes
Source Control	GitHub	Code hosting & webhook trigger
CI/CD Engine	Jenkins Pipeline	Orchestrates the full automated workflow
Build Tool	Maven	Executes clean package → generates .war
Code Quality	SonarQube	Static analysis, vulnerabilities & quality gate
Artifact Repository	Nexus	Stores versioned .war artifacts
Application Server	Apache Tomcat 9	Hosts and runs the deployed web application
Cloud Storage	AWS S3	Archives build artifacts, reports & logs

All tools run on separate dedicated servers/EC2 instances for better isolation, scalability, and real-world simulation.

Pipeline Flow

1. Developer pushes code to GitHub
2. GitHub webhook triggers Jenkins Pipeline job
3. Maven executes clean package → generates .war file
4. SonarQube performs code scan and enforces quality gate
5. Successful build → .war uploaded to Nexus Repository
6. Jenkins deploys the .war to Tomcat server
7. Build artifacts, Sonar report, and logs backed up to AWS S3
