Project Goal

To build and automate a full CI/CD pipeline using AWS-native services—including CodePipeline, CodeBuild, and Elastic Beanstalk—for the continuous integration and deployment of a Java-based monolithic application sourced from Bitbucket, with persistent backend support via Amazon RDS (MySQL).

Architecture Summary

• Source Code Management: Bitbucket (migrated from GitHub)
• CI/CD Services: AWS CodePipeline + AWS CodeBuild
• Artifact Storage: Amazon S3
• Compute Environment: Elastic Beanstalk (Tomcat platform)
• Database: Amazon RDS (MySQL 8.x)
• VPC & Security: Security Group-level isolation for RDS access, IAM-managed permissions
• Monitoring & Debugging: AWS CloudWatch Logs for build and deployment observability

Pipeline Flow

1. Elastic Beanstalk Environment Configuration

• A new Elastic Beanstalk environment was created using the Tomcat 8.5 platform.
• Session stickiness was explicitly enabled to ensure user session persistence under load balancer routing.
• The environment launched two EC2 instances behind an AWS-managed Application Load Balancer (ALB).

2. Amazon RDS Setup & Secure Integration

• An Amazon RDS instance was provisioned with MySQL as the engine.
