Whose responsibility is it to establish the prerequisite CICD pipelines, HITL workflows, and Observability infr in order for devs to shepherd changes to prod (and track their impact)? Hint: it's not the developer's.
But those things all require more pods on the cluster! We've looped back around to the beginning.
This was the point of "devops" (the concept, not the job title): the team should be responsible for development and operations, so one isn't prioritised hugely over the other.
