Serverless Feedback Collection System using AWS

A lightweight, serverless web application that collects user feedback in real-time using AWS services — without any backend server. Ideal for college mini-projects, feedback systems, and AWS practice.

---

📌 Project Overview

This project uses a fully serverless architecture with AWS to accept and store user feedback through a static web form. It eliminates the need for traditional server hosting or complex backend configurations.

---

🎯 Objective

Build a feedback collection system using the following AWS services:

• Amazon S3
• API Gateway
• AWS Lambda
• DynamoDB

---

🧩 Problem Statement

Traditional feedback systems require managing infrastructure like servers and databases. This adds cost, maintenance, and complexity.

This project simplifies that using serverless services — reducing effort while improving scalability and ease of deployment.

---

✅ Key Features

• 100% Serverless – No servers to manage
• Cost-Efficient – Pay only for usage
• Real-Time Storage – Immediate data capture via DynamoDB
• Frontend Hosted on S3 – Easy static web hosting
• Secure and Scalable
• Monitoring via CloudWatch Logs

⚙️ How It Works

1. User opens the HTML feedback form hosted on Amazon S3
2. On submission, form sends a POST request to API Gateway
3. API Gateway triggers a Lambda function
4. Lambda processes the feedback and stores it in DynamoDB

---

🚀 Implementation Steps

1. Create DynamoDB Table

• Table Name: Feedback
• Primary Key: id (String)

2. Lambda Function

• Parses JSON input from API Gateway
• Generates a unique ID and timestamp
• Writes data to DynamoDB

3. Configure API Gateway

• Route: POST /submitFeedback
• Integration: Linked to Lambda
• Enable CORS for frontend access

4. Upload Frontend to S3

• Upload index.html
• Enable Static Website Hosting
• Form uses fetch() to send data to the API Gateway URL
