> run it in a beta environment
Every Uber/ex-Uber engineer is nervously chuckling at this comment right now
As the saying goes, Everyone has a Test environment. Some people are lucky enough to have that distinct from Production.

I'm actually more confused after reading that. I assumed that you meant that tested in production on purpose, but it sounds, at a skim, like they do non-prod testing environments - in fact, it looks like they've gone to having multiple beta environments of every service?
My understanding is that they have a "tenancy" variable in every service call which can take a different code path. They seem to only have one environment for everything and do tests/experiments at code level based on this variable.

Ah, thanks; that explains it nicely
I don't see any need to deploy a big change at once in the software world today. At worst feature gate the thing you want to do and run it in a beta environment, but still push the actual code down the pipeline.
