  • 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.
