What is Content Delivery?
The process of distributing and serving content to users from locations geographically close to them for faster load times.
Content Delivery is a intermediate-level concept that sits in the Web & Content Delivery area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Content Delivery" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.

CDN
A network of servers distributed globally that caches content close to users. Netflix uses CDNs to stream video from servers near you, not from one central location.
Caching
Storing frequently accessed data in a faster storage layer so you don't have to fetch it from the original (slower) source every time.
Latency
The time delay between sending a request and getting a response. Amazon found every 100ms of extra latency costs 1% in sales.
