XYZ Compute Cloud is a web service that provides resizable computer capacity in the cloud. It makes web-scale computing easier for developers. It provides companies with complete control of their computing resources and lets them run on Amazon’s proven computing environment. It also allows companies to quickly scale capacity, both up and down, as their computing requirements change.

What type of cloud computing service is XYZ Compute Cloud providing?

Software as a service (SaaS)

Infrastructure as a service (IaaS)

Platform as a service (PaaS)

In IaaS, the consumer is provided with fundamental computing resources such as processing power, storage, networking components, or middleware. The consumer can control the operating system, storage, deployed applications, and possibly networking components such as firewalls and load balancers, but not the cloud infrastructure beneath them. As XYZ provides companies with complete control of their computing resources, it is providing infrastructure as a service.

Software as a service (SaaS) provides the application but does not control the operating system, hardware, or network infrastructure on which it is running.

Platform as a service (PaaS) provides consumers with a hosting environment for their applications. The consumer controls the applications that run in the environment but does not control the software, hardware, or network infrastructure on which they are running.
