🚀 Serverless Visitor Counter Cloud App

A serverless web application that displays and tracks website visitors using AWS cloud services. The project uses a fully serverless architecture where AWS manages the backend infrastructure automatically.

🏗️ Architecture

User | v S3 (Static Website) | v API Gateway | v AWS Lambda | v DynamoDB

☁️ AWS Services Used

• Amazon S3 – Hosts the static website (HTML, CSS, JavaScript)
• API Gateway – Provides API endpoint for frontend-backend communication
• AWS Lambda – Handles visitor count logic
• DynamoDB – Stores visitor count data

✨ Features

• Static website hosting on AWS S3
• Serverless backend processing
• Visitor count stored in DynamoDB
• API-based communication
• Scalable and cost-effective architecture

⚙️ Project Flow

1. User opens the website hosted on S3.
2. Frontend sends a request to API Gateway.
3. API Gateway triggers the Lambda function.
4. Lambda updates the visitor count in DynamoDB.
5. Updated count is displayed on the website.

🛠️ Deployment Steps

1. Create an S3 bucket and enable static website hosting.
2. Upload frontend files (HTML, CSS, JS).
3. Create DynamoDB table to store visitor count.
4. Create Lambda function with DynamoDB access.
5. Connect Lambda with API Gateway.
6. Integrate API endpoint with frontend.
