InsightaaS: After a one-week hiatus (even ATN gets the odd vacation!), the Sunday Infographic is back – this time, with a terrific look at data centers developed by WhoIsHostingThis.com, and posted on CloudTweaks. It moves quickly from the lowest-common-denominator (what’s a server? What’s an IP address?) to some really interesting material (the impact of union vs. non-union labour on construction costs, use of design elements like tornado-proof roofs), to some of the essential factors (security, connectivity, power and cooling) in keeping them running. There’s some fun scale info as well – such as “playing Xbox One games with Xbox Live involves using one of 300,000 servers…that’s nearly the worldwide computing power available in 1999”!
