I can answer only briefly, and that's a pretty big topic!

I'll skip the apparently pretty amazing integration between the IDE and source control and the build/test system since I didn't use the IDE very much.

I'll just very briefly mention Tupperware, which one might characterize as an internal kind of Kubernetes, except it's so much more, but more importantly, it's way easier to use.

I did write a small, fairly simple stand alone service in Python. It's super, super easy to get something like that 'going', as far as permissions, ingress and egress, storage, all of the real-life complications I've had to deal with, with variable levels of automation/'ease', at other organizations.

I'm out of time for now!
