More about Content Delivery Network (CDN)

Content delivery network, also known as content distribution network, is a term that denotes a collection of distributed servers that help transmit various types of web content to an end user. This transmission is based on the source of the content, the transmission path and the proximity to its end destination.

Simply put, the Global spread of such networks helps get the content physically closer to the end user, diminishing delivery time to improve the end-user experience. At the same time, CDN also provides caching capabilities, which minimize bandwidth usage by delivering cached content from the CDN itself, instead of the original server.

Modern day CDNs push the envelope even further. Such CDN use the reverse proxy mechanism to provide their clients with an additional layer of security, using intelligent methods of real-time traffic profiling, which block spammers, isolate scrapers and hackers and even mitigate DDoS attacks, before they can reach your servers.

Most sought-after CDN benefits include:

  • Accelerated delivery
  • Optimized caching
  • Website security
  • Protection from distributed denial of service (DDoS) attacks
  • Better search engine optimization (SEO)
