A hospital team deploys its own patient-portal code. The cloud provider patches the operating system and the runtime, and the team does not manage virtual machines. Which service model is this?
Select an answer to reveal the explanation.
Short Explanation
You brought the recipe and the provider owns the kitchen, the ovens, and the building permits. That split is platform as a service. If you were also maintaining the stoves, it would be infrastructure as a service, and if you only sat down and ate a finished meal, it would be software as a service.
Full Explanation
Platform as a service lets the customer deploy application code while the provider operates the runtime, the operating system, and the underlying machines. The hospital team deploys its own portal and does not patch the operating system or manage virtual machines, which matches that split. Infrastructure as a service hands the customer virtual machines, and the customer patches the guest operating system. That is more responsibility than this team kept. Software as a service is a finished application the customer uses. The customer does not write and deploy the portal code. A cold site is a disaster-recovery facility with space and power, not a cloud service model for running custom code. Exam caveat: the labels describe responsibility, not a particular vendor's product name. A database service can be platform as a service even when the menus look like infrastructure. Operational check: list who patches the runtime and who ships the code. If the provider patches the platform and the hospital ships the portal, keep the design in platform as a service.
