Vendor-supported systems in cloud computing are exemplified by which service models?

• A. They are on-premises software only.
• B. They refer to custom in-house applications.
• C. They are cloud-based offerings like SaaS, PaaS, and IaaS.
• D. They are obsolete legacy systems.

Answer: (C)

Vendor-supported systems in cloud computing are the cloud-based offerings provided by the provider, with the provider handling hosting, maintenance, and updates. The three service models that exemplify this are Software as a Service, Platform as a Service, and Infrastructure as a Service. In SaaS, you use software applications over the internet that are fully managed by the vendor. In PaaS, you have a ready-made platform to develop, run, and manage your own applications without worrying about the underlying hardware or middleware. In IaaS, you rent computing resources like virtual machines and storage, while the vendor takes care of the infrastructure and basic operations. This shared responsibility and ready-made, externally hosted services are what define vendor-supported cloud systems. On-premises software is hosted and maintained inside an organization's own environment, not by a cloud provider. Custom in-house applications are developed and run internally rather than delivered as cloud services by a vendor. Legacy systems refer to older technology that isn’t aligned with current cloud service delivery models.
