Design an E-commerce Website like Amazon

Functional Requirements:

• Users can browse and search for products by category, name, or keywords.
• Users can view detailed product information, including price, images, and description.
• Users can add products to a shopping cart and update quantities.
• Users can register, log in, and manage their account information.
• Users can place orders and view their order history.
• Admins can add, update, or remove products from the catalog.
• The system supports basic payment processing (integration with a payment gateway).

Non-Functional Requirements:

• The website should be available 24/7 with minimal downtime.
• The system should be able to handle moderate traffic (e.g., thousands of users per day).
• Product and order data should be consistent and not lost.
• User data and payment information must be stored securely.
• The website should load product pages within 2 seconds under normal load.
• The system should be designed so it can scale horizontally as traffic grows.
