The complexity is in what is a service, pod, job, etc. not in the CRUD model. It's like describing driving a car as "the accelerator, brake, and clutch are all pedals; you press them to activate their functionality; pretty intuitive"
This car has tires, you create, delete and patch them. It also has an axels, gas tank, etc.
This truck has tires, axels, has tank
This motorcycle has tires, axels, etc
sounds like kubernetes?
