Dropbox was founded by engineers, and the ethos of technical innovation is fundamental to its culture. Dropbox’s Databases team of SREs manage thousands of MySQL servers, which requires a deep understanding of MySQL, automation, Linux, Python, hardware, performance tuning, monitoring, and reliability.
Dropbox has grown enormously since launching in 2008, surpassing 500 million sign-ups and 500 petabytes of user data. To give a sense of the incredible growth it’s experienced, Dropbox had only about 40 petabytes of user data in 2012. In the four years since, it has seen over 12x growth. Tammy Butow offers an overview of how Dropbox database infrastructure has scaled.
