Why each option
An organization seeking to avoid OS patch management should choose Platform as a Service (PaaS) because the cloud service provider is responsible for managing the operating system, including patching.
In PaaS, the service provider manages the operating system, not the customer.
In Infrastructure as a Service (IaaS), the customer is responsible for managing and patching the operating system.
In a Platform as a Service (PaaS) model, the cloud service provider is responsible for managing the underlying infrastructure, including the operating system, its patching, and maintenance. This offloads the burden of OS patch management from the customer, allowing them to focus solely on application development and deployment.
In Infrastructure as a Service (IaaS), the customer is responsible for managing the operating system, including patching. The service provider only manages the virtualization and physical infrastructure.
