What is beneath Wordpress.com?

I was going through Matt (founder of Automattic - the company behind wordpress.com) blog, and found some interesting facts on the infrastructure specification of wordpress.com. It is actually quite amazing figure
We'are having 8,921 CPU cores across 2,475 physical processors, 8,200 gigabytes of memory (RAM). We’ve changed how we’ve done storage, but now that layer includes on its own 1.3 terabytes of RAM, 1.3 petabytes of storage, and 8.9 terabytes of solid state disks. (Plus Amazon S3, which we use as backup to our internal systems.) - Matt said.

That's crazy for running one site but still they are getting DDoS attacks and site is facing issues serving the requests. So what is the next to keep such site running and keeping uptime close to 100%? Can that be catered through cloud computing?

On the similar lines - I recommend http://highscalability.com/ to you, they write about highly scalable architectures and system around the world.
