Amazon's Build System
My time at amazon is what firmly convinced me that the “monorepo is the only way to develop at scale” folks just hadn’t seen something like Brazil.<p>It (and apollo) were truly a work of art and they were designed and built so long before everyone else was talking about reproducible builds.<p>Apollo had us deploying exact copies to our dev environments before docker came along and made it easy.<p>I have no idea how the designers had so much foresight.
