Overview of Project ☁️

In this project, we'll be developing a serverless cloud dictionary application where users can:

• Search for terms related to cloud technologies.
• View the definitions of cloud terms.
• Utilize a serverless architecture using AWS services.

The application will use Lambda for backend processing, API Gateway for managing the API endpoints, and DynamoDB for storing the dictionary terms and their definitions.

The frontend, a React application, will be hosted on AWS Amplify, and API requests will be made to interact with the database.

Services Used 🛠

1. AWS Amplify: Host the frontend React application. [Frontend Hosting]
2. AWS Lambda: Handle API requests for retrieving terms and adding new ones. [Backend Processing]
3. AWS API Gateway: Manage API endpoints to allow communication between frontend and Lambda functions. [API Management]
4. AWS DynamoDB: Store dictionary terms and definitions. [Data Storage]
5. IAM Roles & Policies: Secure access to AWS resources like Lambda, DynamoDB, and API Gateway. [Permissions]

Steps to be performed 👩‍💻

In the next few lessons, we'll be going through the following steps.

1. Setup frontend and host it on AWS Amplify
2. Configure DynamoDB to store Cloud Definitions
3. Create Lambda function for fetching terms
4. Setup API Gateway for API management

Clean Up 🗑️

• Delete API Gateway Resources:
  • Go to the API Gateway console. Delete the REST API you created for the application.
• Delete Lambda Function:
  • In the AWS Lambda console, delete the Lambda function used for fetching terms from DynamoDB.
• Delete DynamoDB Table:
  • Go to the DynamoDB console. Delete the table to avoid any unnecessary charges.
• Delete Amplify App:
  • In the Amplify Console, go to your app and click Delete to remove the Amplify hosting environment.
• Remove IAM Roles:
  • In the IAM console, remove any IAM roles created for Lambda or API Gateway (e.g., Lambda execution roles).
• Remove GitHub Repository (optional):
  • If the repository is no longer needed, delete it from your GitHub account.
