Linux, Open Source Software Pay Off for PayPal

Filed under: linux, Open Source, PayPal, Red Hat — tuxicity @ 2:27 pm

A story about PayPal and how it uses Linux to make the system secure, reliable and cost-effective.

Paypal uses Red Hat Linux.

A few quotes:

“When you’re buying lots of Big Iron, as I did in other places I’ve worked, your upgrade path is US$2 million, US$3 million at a clip. You just had to buy big chunks of stuff to scale,” he says. “Here at PayPal, our upgrade path is 10 US$1,000 no-name servers, slapped into the midtier of the platform. And we just keep scaling it that way. It’s unbelievably cost effective.”

“Rather than have a monolithic box, or an impenetrable fortress that never breaks, we just have so many [nodes] that the breakages are irrelevant,”

“The combination of Linux and open source allows us to do the modifications we need to scale and have that extreme rigidity of security,”

“Sometimes we feel a little schizophrenic,” he says. “We’re a Web company; we’re a real-time payment system — oh, dear. So doing both is very hard.”
