BAD HARDWARE WEEK

Meet the Man Who’s Rewiring Google From the Inside Out
“The cloud is young: much to do, many left to reach.”
When you spread data across hundreds of machines, the theorem explains, you can guarantee that the data is consistent, meaning every machine using the system has access to the same set of data at the same time. You can guarantee that the system is always available, meaning that each time a machine requests a piece of information, it receives a definitive response. And you can guarantee partition tolerance, meaning the system can continue to operate when part of the system fails. But you can’t guarantee all three. You can guarantee two of the three, but not all. “If you’re working with a large-scale distributed system,” explains Seth Gilbert, now an assistant professor in the department of computer science at the National University of Singapore, “you can’t get everything you want.”
