Guaranteeing Fast and Reliable Content Delivery


This is a technique to deliver content to internet users safely and quickly. It is mainly used in sending multiple image files, downloading large files, streaming videos smoothly, etc. It sends the contents from the origin server of the customer and provides a faster and more stable network environment by distributing from the nearest place to the users of the customer. It is especially useful for game companies where large files need to be distributed at once, shopping malls where multiple images need to be loaded, E-learning website where video classes need to be provided, etc.

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.
