Building Your Own CDN for Fun and Profit

Re:Building Your Own CDN for Fun and Profit by rsync on Wednesday February 14, 2018 @03:32PM (#16379117)

I have always thought it would be a fun and inspiring project to deploy a global CDN ... my career and my lifelong hobby have both been "UNIX sysadmin" and I love running networks ...

However, I spoke about this to some ISP/NANOG folks that I trust and they said that running a real CDN is a nightmare because all of your links (providers) hate you ... you're producing the exact opposite of the traffic that they want and they will not give you any breaks or help or benefits since you are their worst customer.

How accurate was that assessment ?

It depends on the scale. Running a personal blog with sub-1MiB/s traffic is not a problem. I've seen some larger projects though where detailed data analysis had to be employed to debug bad connections... that's not a one-man-job and it was a serious headache to work around some of the less... neutral providers.

I have also heard the same. An interesting thing to do would be to also be a commercial ISP (i.e., sell to datacenters and businesses). Now that is the traffic all the ISPs want as outgoing traffic goes to such networks.

Running a Global CDN and ISP might be a tad too ambitious.

Not at all accurate, assuming the "real CDN" is well run.
