The Gold Fig founders know what they're talking about here. Vikrum ran devops for Firebase from the first server in 2011 up to millions of users after the Google acquisition. Greg was the TL for the Firebase Realtime Database, our flagship product that powers a huge number of apps. They're experts, not only because of what they learned building Firebase, but also because they got insight into how our big customers ran their services and teams.

Vikrum actually built a browser plugin at Firebase that was simple but incredibly useful. It color-coded cloud settings pages for different environments (prod, staging, dev) to prevent someone from accidentally changing the config in prod when they didn't mean to. We required the whole Firebase team to use it, and it honestly saved us from multiple downtime incidents.

If you're managing a service, I really suggest you try Gold Fig out. You can get the benefit of everything that Greg and Vikrum have learned (painfully from years of real experience) about how to run services and be safe with your config!
