> Now, for immutable infrastructure, you have a whole different set of problems. All your changes are nicely logged in git, but to deploy you need to rebuild containers and roll them out over a cluster. The real issue is that it effectively forces externalizing nearly all state. On the surface, this seems like it's just a good thing, but if you think about the limitations and complexity it creates, it starts seeming less unquestionably good. Sometimes that complexity is warranted, but very frequently it is not. That being said, I think modifying code is a running system without pretty strict procedures/control around it is... dangerous. I've seen hotfixex get dropped/forgotten because it only existed on running system and not in source control more than a couple of times.
