Proposal

“Leaf” Clothing E-commerce Website

Using AWS Services Integration to Optimize the System (S3, CloudWatch, etc.)

1. Executive Summary

Leaf is an e-commerce platform specializing in fashion products for men and women, including fashion accessories such as jewelry, shoes, hats, and leather straps. The website integrates AWS services to optimize costs and enhance the user experience.

2. Problem Statement

Problem:
A clothing store needs its own e-commerce channel to optimize the user experience.

Solution:
Create a dedicated e-commerce website for the store using AWS services to optimize cost, time, and user experience.

3. Solution Architecture

The platform applies an AWS Serverless architecture to manage data.

Components and Roles in the AWS Architecture

A. User Interface Layer

Service	Role	Detailed Description
AWS Amplify	Website deployment	Hosts static websites (React, Vue, Next.js) and automatically builds/deploys when code is pushed to GitHub.
Amazon CloudFront (CDN)	Improve page loading speed	Caches static content (images, CSS, JS) close to users to reduce latency and bandwidth usage.
Amazon S3	Store static files & product images	Acts as a content repository for images, banners, CSS/JS files.

B. Application Logic Layer

Service	Role	Detailed Description
Amazon API Gateway	API gateway	Receives requests from frontend and forwards them to Lambda functions for processing.
AWS Lambda	Server-side logic	Handles order processing, payments, authentication, email sending, without dedicated servers.
Amazon DynamoDB	NoSQL database	Stores products, accounts, orders, shopping carts, offering high speed and automatic scaling.
Amazon OpenSearch Service	Product search	Allows users to quickly search products by keywords, color, price, etc.
Amazon EventBridge	Event handling	Automatically triggers events (e.g., new order → send email, update stock).
AWS Secrets Manager	Secure sensitive data	Stores API keys, payment tokens, database passwords to protect data.

C. User Management & Security Layer

Service	Role	Detailed Description
Amazon Cognito	User authentication & management	Supports signup, login, password reset, MFA without building your own auth system.
AWS WAF (Web Application Firewall)	Web protection	Protects against SQL Injection, XSS, DDoS, and other malicious access.
Amazon Route 53	DNS & domain	Manages domain names.

D. Notification & Communication Layer

Service	Role	Detailed Description
Amazon SNS (Simple Notification Service)	System notifications	Sends notifications to admins or users (via email, SMS, or push notifications).
Amazon SES (Simple Email Service)	Transactional emails	Sends order confirmations, promotions, password reset emails, etc.

E. AI & Machine Learning Layer

Service	Role	Detailed Description
Amazon Translate	Content translation	Translates product descriptions to other languages for international customers.
Amazon Bedrock	AI content generation	Creates chatbots for shopping assistance.

F. Monitoring & Management Layer

Service	Role	Detailed Description
Amazon CloudWatch	System monitoring	Monitors logs, performance, alerts for errors or cost spikes.
AWS CloudTrail	Administrative logging	Tracks configuration changes (who changed what, and when) for auditing purposes.

4. Technical Implementation

Implementation Stages:

Collect system requirements and features
Estimate cost and check feasibility
Design UI prototypes using Figma
Build database schema
Develop frontend interface
Build API, backend, integrate AWS services
Test, deploy, and finalize the project

5. Timeline & Milestones

Month 1: Learn AWS
Month 2: Design and implement the project
Month 3: Deployment and testing
