A mayor asks for one sentence: who patches Outlook Online versus who patches the guest OS on a cloud virtual machine?
Select an answer to reveal the explanation.
Short Explanation
Short version for the mayor: Microsoft keeps Outlook Online healthy; if you rent a VM, you still own the guest OS updates. SaaS shifts app patching up; IaaS leaves the OS on your plate.
Full Explanation
Shared responsibility differs by service type. In SaaS scenarios such as Outlook Online, the provider maintains and patches the hosted application. In IaaS, the provider supplies the virtual machine infrastructure, but the customer remains responsible for securing and patching the guest operating system and the software installed on it. Assuming cloud removes all patching, or that one desktop virtualization product covers both cases, misstates the model.
