Why Dropbox decided to drop AWS and build its own infrastructure and network

For starters, a company like Dropbox is dealing with a huge number of customers storing an enormous amount of data. The latest numbers are 500 million users and 200,000 business customers. When they made the transition, they had to move an epic 500 petabytes — that’s five followed by 17 zeros — that had been sitting on AWS servers. (They still use AWS for some workloads.) – Ron Miller, TechCrunch http://tcrn.ch/2f0hhqF
