How to build a CDN?

Hi,

I'm slowly gathering some LEBs and I though about building a small CDN for myself (for learning purposes).

What are important keywords that I have to look for?

Are there any articles worth reading?

The main purpose is to learn how a CDN works. Some questions that come into my mind are:

• How to balance the load?


• How to choose the nearest location to the client?


• How to achieve HA?


• How to synchronize the data?


• How to serve the files (nginx) ?

Thanks in advance, gehaxelt
