Delivers Content Securely and Quickly Using Global CDN Infrastructure

Using edge servers distributed around the world, Global CDN ensures safe and fast delivery of static content stored on a web server or object storage for end users. In addition, it protects the origin server by distributing load during traffic surges, while at the same time provide a fast, reliable web services by downloading content from nearby edge server.

Overview

  • Easy-to-use CDN Service

    Signing up for the Global CDN service is quick and easy thanks to the web-based console on Samsung Cloud Platform. The origin server and caching policy of the Edge server are also easy to set up, allowing for fast content delivery.

  • Enhanced Service Availability

    Even when multiple simultaneous requests cause unwanted traffic surges, edge servers spread across different geographic locations guarantee fast delivery of contents without compromising usability. They also ensure service availability and stable service performance.

  • Use of Secure Contents

    Supporting HTTP, HTTPS, HTTP/2 protocol, content caching with various origin servers are possible. If the TTL of a previously cached content is expired or the origin content
    is updated, existing cache in the edge server will be evicted. New content from the origin server will be cached to process the content request from an end-user, making it possible for users to get the latest content.

  • Efficient Cost Management

    Even in settings that require huge traffic bursts (e.g. downloading a large file), stable service quality is guaranteed without mobilizing massive resources. Usage-based pricing also allows for efficient cost management.
