Principles of Object Storage and CDN
💡 Learning Guide: This article will walk you through a complete chain—from file upload to user download. You'll see how object storage manages massive files like a "smart warehouse," how CDN delivers content to users' doorsteps like a "courier network," and what pitfalls await you along the way. It's recommended to first understand basic HTTP requests and DNS resolution principles.
