What is a CDN?
- A CDN refers to a geographically distributed group of servers that work together to provide fast delivery of Internet content.
- They house content close to the telecom service providers’ networks.
- Majority of web traffic across the world today is routed through CDNs.
- Platforms such as Netflix, Facebook, Amazon — ones with large quantities of data held in global libraries — host their geographically relevant content closer to where that content is to be consumed.
- This ensures the end customer is able to access the content faster.
- Another reason companies rely on these CDNs is to help protect their sites against traffic spikes, distributed denial of service (DDOS) attacks, etc.
