A couple of the CDNs have one or multiple rack minimum deployments. You can get a Netflix box in 4U that does many TB of storage, BGP, etc. CDN in a box. A lot of them were just built with big scale in mind, based on the fact that the US has 10 or so major sites and the scale needed to serve that much of the US. Now it's all about getting to the edge, but they haven't made their deployment smaller to accommodate. Some parts of their businesses evolve very rapidly, while other parts of the same business plod along ridiculously slow. Not meaning to pick on Apple (or Microsoft who's in the same boat), but they're the original reason for this thread. Most of Apple or Microsoft's peak usage (major OS updates) could fit in a 10 year old desktop's RAM drive, provided the rest of the system could keep up with the throughput needs. I'm surprised more companies haven't more quickly adopted something the configuration of the Netflix box. It doesn't have to do everything, just do the high demand stuff well. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Aaron Gould" <aaron1@gvtc.com> To: "Mike Hammett" <nanog@ics-il.net> Cc: Nanog@nanog.org Sent: Wednesday, September 20, 2017 5:34:41 PM Subject: RE: IOS new versions and network load My Netflix servers are half a petabyte of cached movies and they are about 18 inches tall .... not sure what you mean. -Aaron Gould
