5 Common Myths about CDNs that Clog your Content


To help you navigate through the noise and confusion, here is our view on the top 5 myths about CDNs



Content Delivery Networks (CDNs) have been around since the late 90’s and are a key component of IT strategy when it comes to video streaming, social media, and retail/e-commerce.

CDNs have certainly evolved from their beginnings in 1997. Traditional CDNs were built for a read-only web. They relied on centralized DNS servers combined with distributed caching techniques at the edge to take content closer to global end users.  CDNs have done a phenomenal job of speeding the delivery of video and large files to the far reaches of the globe. As the adoption of web applications and related dynamic content needs grew, high-end CDNs started offering Dynamic Site Acceleration services through intelligent routing, TCP optimization and persistent connections. In fact, the majority of the revenue in the CDN market comes from media delivery and e-commerce – which is why customers from this segment get all the attention from CDNs.

Enterprises, however, have been late adopters of CDNs. That is quickly changing. In order to support an increasingly mobile workforce, enterprises have recently started putting a web front-end on enterprise applications (which were previously resident on-premises in datacenters and behind the firewall). Enterprises are realizing productivity benefits as well as higher end-user adoption rates through the use of web application acceleration services offered by a subset of CDN vendors.

CDN services, once restricted to a couple of vendors, are now available from over 40 players in the market. Each vendor brings a slightly different flavor of CDN and functionality to bear. This makes it a lot more difficult for the buyer to choose.

Further complicating the matter is that not everything being said about CDNs is true. To help you navigate through the noise and confusion, here is our view on the top 5 myths about CDNs.
