EVOLVING OUR INFRASTRUCTURE THROUGH THE MESSAGING SYSTEM MODEL IN DROPBOX

Summary from the TLDR Web Dev newsletter

Dropbox's asynchronous platform initially struggled with scalability and developer productivity. To address these issues, its team implemented a Messaging System Model (MSM), inspired by the OSI model, which organizes the platform into five layers: frontend, scheduler, flow control, delivery, and execution. This layered approach simplified the asynchronous interface for Dropbox, making it better to use.
