Explanation

IaaS provides virtualized computing infrastructure (servers, storage, networking) where the customer manages the OS and above, making it ideal for organizations wanting maximum control with minimal hardware investment.

SaaS delivers fully managed, ready-to-use software applications over the internet (e.g., Microsoft 365, Salesforce), where the provider manages everything and users simply consume the service.
