More testable code with the hexagonal architecture #video (2019) - the hexagonal architecture is the name given to an clean and interesting approach to building large “business” applications.

Hexagonal architecture in DDD #video (2015) - another take on this, with some domain driven design bits thrown in. A lot of folks are doing both of these at the same time, and the match seems good.
How we migrated Dropbox from Nginx to Envoy (2020) - in three words - the hard way! This is a surprisingly detailed look at what I can imagine is the equivalent of switching the engine in flight on an airplane.
