>> How did/does the devs create, test new code and debug issues? Can they do that locally on their local laptop? If so, how?

I used to buy the idea of this when there were monoliths.

Then I had the joy of running a shop with dozens of web properties.

Local dev became untenable. My systems admin was an early adopter of Xen. That shop ran like a dream... devs could come in and have a new environment update in place and just start to work. Staying in sync with prod was never a problem.

By making systems guys keep devs fed, by making devs work closely with systems folks you get better software. Containers just hid developers shitty decision making in a wrapper that Systems folks can tolerate.

And how DO you debug... cause what you do to figure a problem out locally is not how you trouble shoot when the shit hits the fan in prod. These tools should be the same, sane and well used and loved by everyone. Local debugging is part of the problem, even more so if your service based app that lives and dies on the wire.
