Question

Accepted Answer

The system design for the checkout feature on Amazon involves request body, API calls, load balancing, database caching, and CDN considerations.

Request body includes user's selected items, shipping address, payment details, etc.
API calls are made to process payment, update inventory, and send confirmation emails.
Load balancing ensures even distribution of traffic across multiple servers to handle checkout requests efficiently.
Database caching helps in storing frequently accessed data to reduce load on the database.
CDN considerations involve delivering static content like images, CSS, and JavaScript files quickly to users worldwide.
