Different layers of a platform carry different reliability responsibilities. Deep services (databases, business logic) focus on correctness, middle-layer orchestrators absorb failures through retries and compensating actions, and edge components like load balancers and API gateways prioritize availability above all else, shielding downstream systems from failure. The core argument is that the closer a component sits to the customer, the more it must prioritize stability over other concerns.
