Content Delivery Networks: Opportunities and Challenges


Content Delivery Networks: Opportunities and Challenges



Content Delivery Networks (CDNs) are currently playing a major role in delivering web traffic from content publishers to Internet clients. They are also considered to be one of the fastest growing Internet businesses.

In 2013, CDNs deliver more than 50% of the web traffic in the US and it is estimated to be more than 60% in 2014. This growth is due to the fact that CDNs increase websites global availability up to 99.99%, they can potentially increase content delivery speed up to 10 times, and they can decrease cost to less than one third for publishers. Moreover, they can help publishers to scale globally while also protecting them against flash crowd traffic and vicious attacks. Yet, CDNs are facing numerous challenges for caching content globally and then delivering it optimally to minimize latency.

In this talk, we are going consider some of these challenges and discuss the techniques that CDNs use to accelerate content delivery while being resilient to high traffic and numerous requests.
