IaaS vs PaaS vs SaaS

MediumPython

Problem

What are the key differences between IaaS, PaaS, and SaaS?

Implement cloud_responsibility_matrix(models) to represent those differences programmatically. The input is a list containing one or more of IaaS, PaaS, and SaaS; return one responsibility record per requested model, preserving input order. Each record must identify the layers managed by the customer and the provider.

Constraints

1 <= len(models) <= 3
Each element is exactly one of "IaaS", "PaaS", or "SaaS"
The input contains no duplicate service models
Return records in the same order as the input

Function Signature
