Another quick example - serving up product image assets to customers. Let's say you want to ship 1TB of images to customers per month.
In pre-cloud times, you would spend untold piles of money spinning up racks of storage arrays, switches, firewalls, leasing out gigantic pipes for bandwidth, and again all of the requisite people in order to get that running. You'd rent space in multiple distributed global datacenters, so again you'd have an unreal amount of bash-script-file-sync services so that when someone uploads a new image it gets replicated all over the globe. Millions and millions of dollars. You'd probably have to write a custom resizing service with ImageMagick, hooked into your frontend, so that you were serving customers the correct size and not blowing through your bandwidth allocation. Just incredibly complex.
Today, you click a button in your CDN provider's console; most of that functionality from above just comes for free.
Again you have to do a little bit of munging your front-end to take into consideration the vagaries of your CDN provider, but overall it's such a huge savings of mental energy and time. Put a circa-1999 systems architect in front of the Cloudflare console from today and they wouldn't believe it was real.
