CDN’s Effectiveness: Static Vs Dynamic ContentBack in the day, a CDN’s primary function revolved around caching static content and delivering it efficiently to end-users. Today, 40% of the online traffic is made up of dynamic content, CDN also did their part of the effort to adopt this new reality.

Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. The cache is invalidated on a time basis. Creating an On-Demand builder.
