Project Title

Refactored Deployment of VProfile Application Using AWS PaaS and SaaS Services

Objective

The objective of this project is to modernize and refactor the deployment architecture of the VProfile application by leveraging AWS-managed Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) solutions. The aim is to reduce infrastructure management overhead, increase application scalability and resilience, and align with cloud-native best practices for deployment, networking, and security. The architecture replaces traditional EC2-hosted services with Elastic Beanstalk for application deployment, Amazon RDS for relational database hosting, Amazon ElastiCache for in-memory caching, and Amazon MQ for asynchronous message handling. Additional enhancements include leveraging S3 for artifact storage, integrated load balancing and scaling through Beanstalk, and optional use of Route 53 and CloudFront for DNS routing and content delivery.

Architecture Overview

The refactored architecture adopts AWS-managed services to replace self-managed EC2-based components:

• Application Hosting: AWS Elastic Beanstalk (Java with Tomcat platform)
• Database: Amazon RDS for MySQL (Multi-AZ, private subnet)
• Caching Layer: Amazon ElastiCache (Memcached engine)
• Message Broker: Amazon MQ (RabbitMQ engine)
• Artifact Management: Amazon S3 (WAR file versioning and deployment)
• Load Balancing & Scaling: Elastic Load Balancer (ALB) and Auto Scaling managed via Beanstalk
• Networking & Security: Custom VPC with private/public subnets and dedicated Security Groups
• Optional Enhancements: Route 53 (custom DNS), CloudFront (CDN integration for static content)
