In the past, CDNs have been used to cache and distribute static objects. But issues around invalidation, staleness, and a lack of visibility have prevented us from using CDNs to fully leverage the benefits of caching when it comes to dynamic content. To fully take advantage of the power of modern CDNs, site operators look for better caching, control, and visibility, especially when dealing with dynamic content. In this session, we’ll look at the challenges CDNs have faced with dynamic content and what we should expect from CDNs in order to fully integrate your applications and leverage their global reach.

Specific topics include:

  • The need for an invalidation framework and real-time purging
  • Content control through dependencies
  • The necessity for configuration APIs and real-time functional changes through configuration
  • The demand for real-time logging
  • Examples of real world applications of these principles

Dragos, the talk will cover how CDNs can cache dynamic content and objects that we’ve traditionally not been able to cache on a CDN. I’ll talk about the mechanisms necessary to do this and give a bunch of examples. It’ll be a technical talk, and it should apply to any CDN.

Will this go more into the technical area or will just underline statistics and principal ways of caching?
