Interestingly, the entirety of Google's codebase - from search and maps to YouTube and Google Docs - resides in a monolithic source code repository available to and used by 95% of Google engineers, or about 25,000 users to be exact.

"Without being able to prove it," a Google engineering manager said, "I'd guess that this is probably the largest single repository in use anywhere in the world."

All told, Google's services comprise 2 billion lines of code which, taken together, weigh in at 86 terabytes.

Fascinating.
