The budget is thin so I need to build it using open source tools and software. Most importantly, I want to have complete control over the behavior of the CDN. Meaning, what gets cached, what gets purged, etc. Management has been working on getting servers in key countries so the project is gaining momentum and so is pressure. Akamai, amazon, google, and other contenders are out of the picture for several reasons. So please don't recommend them or any third party vendors.
There are very few tutorials online on how to create one. After several days of scouring the web and filtering through the fluff, I found the following tutorials / walk-throughs:

Most natural diamonds that occur near Earth's surface did not form from coal. These diamonds formed deeper in the mantle than any coal seam has ever been buried or were deposited on Earth's surface in asteroid or meteorite impacts. The most convincing evidence that diamonds were not formed from coal is their age — nearly all of the diamonds that have ever been dated formed at least 100 million years before Earth's oldest land plants. Although some diamonds may have formed as plate tectonics carried coal to great depths, most diamonds were at least a billion years old when the first coal seam was deposited. Link to Original Source
