How to Compare CDN Networks – A Pro Guide

With over 50 CDN providers on the market and each of them offering various terms and conditions regarding pricing, servicing, functionality and reliability, comparing all those vendors and finding the one that fits your needs perfectly can be a daunting and time-consuming task, especially if you’re new to the field.

Regardless of whether you’re looking for a CDN to distribute software, deliver games and apps, stream videos, serve ads, or simply augment your content delivery, ensure 100% website uptime, reduce costs and improve the user experience of your customers, there are a number of metrics that you’ll need to take into account (more on those soon).

It’s important to understand that since the popularity of CDNs has been rising steadily over the past decade, the quality of the service across all providers has improved greatly. This means that trying to evaluate different vendors based on the quality of their service, the reliability of the servers and superior functionality may appear highly misleading. On a large scale, all of these aspects are relatively equal among all market players. Instead, here are two effective ways to approach the CDN comparison procedure, both of which are equally important.

  • Business-wise

The first approach is used to evaluate the needs of your business to determine what type of CDN you’d most likely need to have. The key metrics here include business size, target auditory, global page views/website visits and the geographic areas with the highest volume of website visits.

These metrics are unique for each business and must be determined to choose a CDN vendor correctly. There are a number of easy ways to acquire these metrics – tools like Google Analytics, GeoFli, etc. Some of these metrics can also be tracked directly with the help of the CDN you choose in the future.

  • Vendor-wise

The second approach is directly linked with the first one and is used to analyze the features and functionality of a given CDN provider, taking into account the metrics you’ve determined during the first step. These include pricing, number of PoPs (points of presence) and server speed.

To make everything easier for you, we’ve selected some of the leading CDN vendors on the market and compared them.
