In this episode, we introduce Content Delivery Networks (CDNs) and explore their design, implementation, and role in optimizing data delivery across global user bases. We begin by identifying the common challenges of serving large volumes of data from a single data center, including high latency and resource overload, and explain how CDNs solve these problems.

We'll delve into the functional and non-functional requirements of CDNs, examining how they are designed to improve performance, scalability, and availability. We also break down the architecture of a CDN, covering key components such as proxy servers, routing systems, and origin servers, while walking through the workflow of how a CDN retrieves, delivers, and updates data.

Lastly, we discuss the strategic deployment of proxy servers and the differences between public and specialized CDNs, highlighting the benefits each approach offers. Join us to gain a comprehensive understanding of how CDNs enhance content delivery and keep the internet running smoothly.
