Exponentiation with AWS

This is a simple web application that allows users to perform exponentiation - computing the power of a base number to an exponent. It's designed as a demonstration of integrating various Amazon Web Services (AWS) services to create a serverless application that's scalable and easy to deploy.

Features

• User Input for Base and Exponent: Users can enter a base number and an exponent to compute the power operation.
• Serverless Architecture: Utilizes AWS services for a fully serverless operation, ensuring scalability and low maintenance.

Architecture

The application uses the following AWS services:

• AWS Amplify: Automates the deployment and hosting of the web application.
• AWS Lambda: Executes the backend logic without provisioning or managing servers.
• Amazon API Gateway: Manages the APIs that trigger AWS Lambda functions.
• Amazon DynamoDB: Stores and retrieves data required by the application.
• AWS IAM (Identity and Access Management): Manages access to AWS services and resources securely.

Setup and Deployment

Prerequisites

• AWS Account - Ensure that you have an AWS account set up. If not, you can create one at AWS.
• AWS Free Tier - This project can be deployed within the AWS Free Tier limits.
• Basic knowledge of AWS services.
• Programming languages - Python, HTML/CSS, JavaScript.

Steps

1. AWS Console Setup:

   • Log in to the AWS Management Console.
   • Navigate to the respective service sections (Amplify, Lambda, API Gateway, DynamoDB, IAM) to configure and deploy each component.

2. Deploying the Web Application:

   • AWS Amplify:
     • Create a new Amplify project and link it to your GitHub repository containing the web application's code or manually upload the zip folder containing 'amplify_Index.html'.
     • Make sure to replace the placeholder with your API link.
     • Deploy the application; Amplify will automatically build and host your application.

3. Setting Up the Backend:

   • Amazon API Gateway:
     • Create a new API using the Amazon API Gateway service.
     • Define a new resource and method (POST) that triggers the AWS Lambda function.
     • Navigate to '/' and enable Cross-Origin Resource Sharing (CORS).
   • AWS Lambda:
     • Create a new Lambda function using 'lambda_Function.py' as the code for computing power.
     • Replace the placeholder with your table name.
     • Test and deploy the Lambda function.
   • Amazon DynamoDB:
     • Create a new table to store the results.
     • Navigate to Configuration > Permissions > Policy, this will redirect you to IAM.
   • IAM Configuration:
     • Use 'dynamoDb_Policy.json' to configure a new policy for the table.
     • Make sure to replace the placeholder with your table ARN.

Usage

• Access the web application hosted by AWS Amplify via the URL provided after deployment.
• Enter the base number and exponent in the provided fields and click "Calculate" to see the results.
