Here’s yet another wonderful technical deep dive from the Dropbox team. Setting apart their recent drama in the Apple world and failure after failure in trying to find something more to offer than “just” the basic syncing feature, their sheer scale and infrastructure related topics are always interesting to me. No doubts the shortcomings are not part of the engineering team as their syncing function is still number one in the industry. Here I learned few more things about their infra, NGINX + lua setup and migration to Envoy. It’s a long read but well written and very rewarding.
