At our July Test in Production Meetup we focused on testing systems and processes at scale. Girish Patangay, Manager and Engineer at Facebook, kicked off the evening with a talk about how there are different versions of Facebook in the real world. “This talk is about how not all Facebook looks the same. Even in this room, all you folks have different versions of our software, mainly because of Gatekeeper. So if you think about this, each person just has a slightly different version and the way we use Gatekeeper, even today, is almost everywhere through our entire stack.” Watch his talk to learn more about what happens after you roll out a feature. After you’ve released it, when you want to tweak it, what you can see, and how you can make it better.
