Note Taking Web App - Three-Tier Architecture

Project Overview

The Note Taking Web App is designed as a three-tier architecture deployed on AWS infrastructure. The application allows users to create, read, and delete notes with a simple interface. The primary focus is on implementing a robust three-tier architecture rather than complex application features.

Core Functionality

• Add new notes
• Delete existing notes
• View all notes

Architecture

What is a Three-Tier Architecture?

A software architecture pattern that separates an application into three logical tiers:

• Presentation Tier: Responsible for user interface and experience
• Logical Tier: Processes user requests, performs calculations, and interacts with the data tier
• Data Tier: Stores and manages the application's data

AWS Services Utilized

• Amazon EC2 (for Web-Server and App-Server)
• Amazon Auto Scaling group (Scale on demand)
• Amazon VPC (Virtual private cloud: Private Network)
• Amazon RDS (Relational database services: Database)
• Amazon S3 (Stores the front-end user interface of the website)
• Amazon Load Balancing (External and internal ALB)
