A company rents virtual machines from a provider, patches the guest operating systems itself, and does not own the hardware. Which cloud model is that?
Select an answer to reveal the explanation.
Short Explanation
The company is renting the building and doing its own housekeeping inside. That rental of machines is infrastructure as a service. A finished application, a platform where you only bring code, or a hypervisor sitting on a laptop is a different deal than machines the company itself patches.
Full Explanation
Infrastructure as a service provides virtual machines and leaves the guest operating system to the customer. The company patches those guests and does not own the hardware, which is this model. Software as a service is a finished application the provider patches. A customer who patches the guest operating system is doing more than using a finished app. Platform as a service lets the customer deploy application code onto a runtime the provider maintains. The customer is not described as bringing only code. It is renting machines and patching their operating systems. A type 2 hypervisor is software on a local host operating system. It is not the name of rented provider hardware. Exam caveat: the customer still has to patch and back up the guests. The provider's responsibility stops at the infrastructure. Operational check: list who applies guest updates. If the company does, keep the design classified as infrastructure as a service. Name the team that patches the guests so the model stays infrastructure as a service at the next review.
