From InfoWorld: After years of relying on the Amazon cloud to store its users' files, Dropbox has shifted gears and begun using primarily its own technology instead.
"We're excited to announce that we're now storing and serving over 90 percent of our users' data on our custom-built infrastructure," the company said in a blog post Monday.
Dropbox stores two kinds of data: file content, and metadata about files and users. The service always had a hybrid architecture, whereby metadata was stored on Web servers in its own data centers while file content was stored on Amazon.
Growth prompted Dropbox to start building its own storage system back in 2013, leading to an initial launch in early 2015. By October, it had hit its goal of serving 90 percent of its data from its in-house infrastructure.
