1000 servers per week number is not just realistic. I will like to believe the author misspoke otherwise it will take more that Zynga employees just to configure 1000 servers in a week time.
1000 servers is not at all unrealistic if you've automated the process.
It's likely fully automated since it's running on EC2
Umm... With EC2, which is what they often use, powering up and configuring 1000 machines can take 10 minutes or so, give or take a ramped boot. :-)
It makes you wonder how many servers Amazon adds per week..
That's a question I'd like the answer to. A normal customer is limited to 20 on-demand or reserved instances per region. Could anyone request to have that limit raised to 1000 per week?
