Is that 80,000 physical or virtual servers though? That ratio could easily be 10:1 if it is the VM count which is more what I would be expecting.

The article says 10,000 servers, so maybe there's an 8:1 ratio

Unless I read it wrong the article says 10,000 servers going live this summer with the plan being to replace all 80,000 servers in total.

edit: just noticed they sneak "and eBay" into the 80,000 total server count. Makes a little more sense now :)

eBay doesn't have anything close to 80,000 servers.

I doubt they are optimizing for performance of reporting.
