Inside Google's brain: Search giant reveals how massive network that delivers every search request, YouTube video view and Gmail works
Google has given a rare glimpse inside the vast data centres around the globe that power its services.
The firm has revealed how the intricate maze of computers that process Internet search requests, show YouTube video clips and distribute email for millions of people works.
The search giant revealed it now runs over 100,000 main 'warehouse scale' servers worldwide, and that they communicated at a blisteringly fast 10Gb/s in the 'Jupiter' network.
Google also admitted that to get the network performance it needed, it has been building its own hardware.
'Pursuing Google's mission of organizing the world's information to make it universally accessible and useful takes an enormous amount of computing and storage,' said Amin Vahdat, a Google Fellow.
'In fact, it requires coordination across a warehouse-scale computer.
'Ten years ago, we realized that we could not purchase, at any price, a datacenter network that could meet the combination of our scale and speed requirements.
'So, we set out to build our own datacenter network hardware and software infrastructure'.
At the ACM SIGCOMM conference, the secretive search giant revealed how the system works.
'From relatively humble beginnings, and after a misstep or two, we've built and deployed five generations of datacenter network infrastructure.
'Our latest-generation Jupiter network has improved capacity by more than 100x relative to our first generation network, delivering more than 1 petabit/sec of total bisection bandwidth.
'This means that each of 100,000 servers can communicate with one another in an arbitrary pattern at 10Gb/s.'
Google says this speed has helped its products.
