AWS Lift-and-Shift VProfile Project

Overview

This project demonstrates the deployment of a multi-tier web application stack on AWS, using a lift-and-shift strategy to migrate a production environment. The architecture leverages AWS services such as EC2, ELB, S3, Route 53, IAM, and Auto Scaling to create a scalable, reliable, and secure environment.

Architecture

The architecture for this project includes the following components:

• Elastic Load Balancer (ELB): Distributes incoming traffic across multiple EC2 instances to ensure reliability.
• Auto Scaling: Automatically adjusts the number of EC2 instances based on demand, maintaining availability and cost-effectiveness.
• EC2 Instances: Hosts different parts of the application including:
  • Tomcat: Runs the VProfile application.
  • RabbitMQ: Manages message queues for asynchronous communication.
  • Memcached: Provides distributed caching to improve application speed.
  • MySQL: Stores the application’s data in a managed relational database.
• S3 Bucket: Stores the WAR file for deployment, fetched by the Tomcat servers on startup.
• Route 53: Provides DNS routing, mapping a custom domain to the application’s ELB.
• IAM: Manages access and permissions to AWS resources for security.
• ACM: Provides SSL certificates for HTTPS.
