Facebook data centers handle traffic and store data for roughly one billion people per day. Designing the hardware and infrastructure needed to scale to this level has required significant innovation from the Facebook Infrastructure team. In this talk, I present some of the notable innovations in data center power, cooling, and server/storage design that make up our seven global data centers. I also present our approach at ensuring efficient resource utilization by our large software code bases. Most of our major hardware and software designs have been released through the Open Compute Project, ensuring that the Facebook philosophy of “making the world more open and connected” also applies to our research and engineering innovations.
