Software & Data Engineering Project

Serverless Web Application on AWS

Project Description

This project demonstrates a serverless web application built using Amazon Web Services (AWS) technologies. The application allows users to create, read, update, and delete (CRUD) items from a DynamoDB table through a contact form on a web page. The form collects data such as the user's name, email, subject, and message, which is then processed by an AWS Lambda function and stored in a DynamoDB table.

Project Architecture

The project architecture consists of:

• DynamoDB: A NoSQL database used to store user-submitted data from the contact form.
• AWS Lambda: A serverless compute service that processes the data submitted by the contact form and performs CRUD operations on DynamoDB.
• Amazon S3: Used for hosting the static files of the web application (HTML, CSS, JavaScript).
• Amazon CloudFront: A content delivery network (CDN) used to distribute the S3-hosted web application for low latency and better performance.

Project Setup

Steps to Build the Project

1. Create a DynamoDB Table

   • Create a DynamoDB table (e.g., studentMessage) to store items with attributes like id, name, email, subject, and message.

2. Build the Lambda Function

   • Write and deploy a Lambda function to handle incoming requests and store data in DynamoDB.
   • The Lambda function processes data sent from the contact form, checks for required fields, and stores it in the DynamoDB table.

3. Set Up S3 for Static Hosting

   • Create an S3 bucket to host the HTML, CSS, and JavaScript files of the web application.
   • Enable static website hosting on the S3 bucket and upload the static files.

4. Create a CloudFront Distribution

   • Set up a CloudFront distribution to serve the static files stored in S3 for better performance and low latency.
   • Configure the distribution to point to your S3 bucket as the origin.

Frontend Code

All the code you can find in the following GitHub Repository

   git clone https://github.com/sachinsingh2156/SDE-serverless-project-on-AWS.git

Expected Outcome

By completing this project, you will have:

• A fully functional serverless web application hosted on AWS.
• Experience using AWS services such as Lambda, DynamoDB, S3, and CloudFront.
• Hands-on skills in building and deploying serverless applications on AWS.

Conclusion

This project provides practical experience in cloud computing, serverless architecture, and AWS integration. It demonstrates how to set up a simple yet powerful serverless web application to handle CRUD operations without traditional server management.
