Content Delivery Network – Part 2: Benefits and Features

Part 2 of this 6-part series discusses the benefits and features of Alibaba Cloud CDN.

By Shantanu Kaushik

Content comprises everything on the Internet. Everything we do on the Internet centers around exchanging information or content between multiple servers and clients. The network of connected machines serves one purpose of enabling information sharing.

A Content Delivery Network (CDN) sits between the content source and the user to provide a seamless user experience without any service interruptions in data delivery. CDN cuts down a lot of time between user requests and content delivery by caching content on the edge nodes that are geographically closer to the user (the content request source.)

In this article, we will discuss the benefits and features of Alibaba Cloud CDN.

What Does a CDN Offer?

As the name itself suggests, the main job of a CDN is to deliver content to the user. However, there is a lot more to Alibaba Cloud CDN than content delivery. Let’s take a look at the prime benefits and features of Alibaba Cloud CDN:

1.  Performance

  • Alibaba Cloud CDN provides accelerated content delivery with bandwidth-hogging content, such as audio and video streaming, livestreaming, and large file downloads.
  • Alibaba Cloud also introduced Dynamic Route for CDN (DCDN) and Secure Content Delivery Network (SCDN) to provide accelerated content delivery based on various usage scenarios.
  • Alibaba Cloud has the most edge (CDN) nodes in Mainland China. Alibaba Cloud has over 500 nodes spread worldwide to facilitate better and more accelerated content delivery.
  • Alibaba Cloud CDN provides a superior bandwidth capacity that matches (and sometimes surpasses) the bandwidth capacity of the competition.
  • Alibaba Cloud CDN provides a quick response time, enabling a seamless content delivery experience without any delay or performance lapse.
  • Alibaba Cloud CDN has an architecture that enables highly efficient memory management with high-performance caching that utilizes load balancing between multiple vCPUs.
