Dropbox Engineering tells the tale of their new SOA:
The majority of software developers at Dropbox contribute to server-side backend code, and all server side development takes place in our server monorepo. We mostly use Python for our server-side product development, with more than 3 million lines of code belonging to our monolithic Python server.

The single most important takeaway from this multi-year effort is that well-thought-out code composition, early in a project’s lifetime, is essential. Otherwise, technical debt and code complexity compounds very quickly.
