Building your own streaming CDN was famously a $100 million problem 10 years ago. However, over time technologies have evolved, and the use cases for commercial CDNs have become more clear. Specifically, commercial CDNs do not fit all use cases. Some examples of where CDNs are not always a perfect fit include:
- Long Tail Catalogs – content is often not in cache
- Higher Definition Video – increases costs, but not revenue
- User Generated Content – (both public and private) – the upload
- Highly localized known users
Another problem with the use of commercial CDNs is that they are multi-tenant distributed applications that have to be scaled – and sometimes they fail to do that. If you are servicing the video market – you often do not get a second chance if your solution fails to scale.
Until recently, a DIY CDN would have been too complicated, begging for outsourcing to a commercial CDN. New software packages, open source solutions and newer services now make it possible to assemble a private CDN solution with off-the-shelf products.
The benefits are obvious in many cases – and that is why so many companies have pursued this strategy.
