Cloud Computing Models Requiring Customers to Own Operating System Patching

Correct Answer: A.

Option A is correct.

IaaS model requires customers to own the patching of the servers.

Option B is incorrect.

Cloud provider is responsible for patching the Operating System for their PaaS offerings.

Option C is incorrect.

Cloud provider is responsible for patching the Operating System for their SaaS offerings.

Option D is incorrect.

FSaaS is not a valid Cloud Computing model.

Infrastructure as a service.

Platform as a service.

Software as a service.

Of the four cloud computing models listed, only IaaS (Infrastructure as a Service) requires customers to own operating system patching.

IaaS is a cloud computing model in which a third-party provider hosts virtualized computing resources, such as servers, storage, and networking, over the internet. Customers rent and manage these resources, typically using a web-based console or API, and can install and configure any software they require on the provided infrastructure, including operating systems.

Because customers are responsible for the configuration and management of the operating systems they install, they are also responsible for patching and maintaining those operating systems. This means that customers need to regularly apply security patches and updates to the operating systems running on their IaaS instances to keep them secure and up to date.

On the other hand, PaaS (Platform as a Service), SaaS (Software as a Service), and FSaaS (FileSystem as a Service) all offer higher levels of abstraction, which means that customers have less control over the underlying infrastructure and are not responsible for patching the operating systems running on that infrastructure.

PaaS provides a platform for developers to build and deploy applications without the need to manage the underlying infrastructure. SaaS delivers software applications over the internet, typically through a web browser, eliminating the need for customers to manage any infrastructure or software. FSaaS provides cloud-based storage that customers can use to store and manage their data without the need to manage the underlying file system.

In summary, only the IaaS cloud computing model requires customers to own operating system patching. PaaS, SaaS, and FSaaS offer higher levels of abstraction, which means that customers do not need to manage the underlying infrastructure or operating systems.
