Microservices all the way
TL;DR: this is mostly a text version of a presentation I’ve done a couple times (English or Portuguese) on the history of building DigitalOcean’s API gateway. How we made it easier for folks to build new microservices instead of continuing to add code to our monoliths, the successes, failures and lessons learned.
First, where were we?
DigitalOcean had 3 monoliths back in 2016 when we started (all 3 are still alive today, albeit much smaller than they were before). Why were there 3? There is a shared library that contains most of the logic that all 3 applications use, so in reality we had one “monolith library” that was reused at all 3, most logic changes were made into this library and then it would be upgraded at every single app separately. The library still exists today and continues to be updated every once in a while.
