So I=E2=80=99ve clearly got a dog in this fight = (https://athornton.github.io/Tucson-Python-Dec-2019/ et al. (also mostly = at athornton.github.io)) but I feel like Kubernetes is an interesting = compromise in that space. Admittedly, I come to this not only from a Unix/Linux background but an = IBM VM background, but: 1) containerization is a necessary but not sufficient first step 2) black magic to handle the internal networking and endpoint exposure = through fairly simple configuration on the user=E2=80=99s part is = essential 3) abstractions to describe resources (the current enumerated-objects = quota stuff is clunky but sufficient; the CPU/Memory quota stuff is = fine), and 4) an automated lifecycle manager taken together give you a really nifty platform for defining complex = applications via composition, which (IMHO) is one of the fundamental = wins of Unix, although in this case, it=E2=80=99s really _not_ very = analogous to plugging pipeline stages together. Note that _running_ Kubernetes is still a pain, so unless running data = centers is your job, just rent capacity from someone else=E2=80=99s = managed Kubernetes service. Adam=
