Dropbox’s Exodus From the Amazon Cloud

Cade Metz, writing for Wired:

The whole process took two years. A project like this, needless to say, is a technical challenge. But it’s also a logistical challenge. Moving that much data across the Internet is one thing. Moving that many machines into data centers is another. And they had to do both, as Dropbox continued to serve hundreds of millions of people. “It’s like a moving car,” says Dan Williams, a former Facebook network engineer who oversaw much of the physical expansion, “and you want to be able to change a tire while still driving.” In other words, while making all these changes, Dropbox couldn’t very well shut itself down. It couldn’t tell the hundreds of millions of users who relied on Dropbox that their files were temporarily unavailable. Ironically, one of the best measures of success for this massive undertaking would be that users wouldn’t notice it had happened at all.

As Tim Cook says, “We believe that we need to own and control the primary technologies behind the products that we make.”
