How does a CDN mitigate the impact of a DDoS attack?

Question

A Content Delivery Network (CDN) plays a crucial role in mitigating the impact of Distributed Denial of Service (DDoS) attacks by leveraging its distributed infrastructure. At its core, a CDN operates by storing cached copies of a website's content across a global network of data centers. When a user requests content, the CDN directs that request to the data center geographically closest to the user. This distribution model inherently provides a layer of defense against volumetric attacks.

Accepted Answer

In the event of a DDoS attack, where multiple compromised systems flood a target website with an overwhelming volume of malicious traffic, a CDN can effectively absorb and redirect this traffic. Instead of all requests hitting the origin server directly, they are distributed across the CDN's network. If one data center comes under heavy load from an attack, the CDN can automatically shift traffic to other available data centers within its network. This automatic redirection of traffic to unaffected nodes is a key mechanism that helps maintain website availability and protect against complete service disruption.
