Guaranteeing Fast and Reliable Content Delivery

CDN

CDN is a technology used to deliver content securely and quickly to Internet users. It is primarily used for transferring multiple image files, downloading large files, and streaming videos seamlessly. It provides a faster and more stable network environment by transferring the content from the origin server to the CDN cache servers located in various regions and distributing the content from the location that is closest to the user.

CDN in Cloud Environment

By configuring the settings just once, content can be distributed domestically and overseas simultaneously. By distributing the content stored in a volume or storage used in cloud instances (virtual servers) to CDN servers located in various regions of the world, it is possible to deliver the content to users around the world in the fastest and most reliable way.

Reasons for using CDN

  • Instead of directly delivering the content from the client company’s instance (virtual server) to the user, it is transferred via a CDN edge server, which not only improves transfer quality but also reinforces security.
  • Connect your cloud instance (virtual server) to the CDN service and upload the content to the storage, then you will be able to start using the service right away.
  • By configuring the settings just once, you can offer the best transfer speed to your local and overseas users.
