On IaaS the city installed and patched IIS itself; on Azure App Service the team deploys application code without managing that web-server OS. What does the App Service approach illustrate?
Select an answer to reveal the explanation.
Short Explanation
Building IIS by hand is IaaS homework; deploying code to App Service is PaaS letting the platform own that web-server OS layer. Same app idea, different chore list. That contrast is the whole teaching point.
Full Explanation
Azure App Service is a PaaS example: developers deploy applications while the platform manages the underlying OS and web hosting concerns. IaaS virtual machines leave IIS and guest OS management with the customer. The contrast highlights PaaS abstraction versus IaaS responsibility, not a ban on custom code or a private-cloud prerequisite.
