Scenarios where CDN may be less useful

  • If the data is private, such as for large enterprises or supply chain ecosystems.
  • If the content has a low hit rate it might be accessed only few times while it is valid (determined by its time-to-live setting). The first time an item is downloaded you incur two transaction charges from the origin to the CDN, and then from the CDN to the customer.
  • Items that are rarely downloaded will incur the two transaction charges without providing any significant reduction in server load.
