Explanation: 

Detailed explanation-1: -In short, virtualization creates simulated versions of a machine’s software or hardware components, while cloud computing is a model that enables users to access a shared pool of resources conveniently.

Detailed explanation-2: -Virtualization is a component within cloud computing that separates the operating system from the underlying hardware.

Detailed explanation-3: -In a software based virtualization environment, the virtual machines share the same kernel and actually require the main node’s resources. In a hardware based virtualization, the virtualization mechanism partitions the real hardware resources.

Detailed explanation-4: -While cloud computing and virtualization rely on similar models and principles, they are intrinsically different. Simply put, virtualization can make one resource act like many, while cloud computing lets different users access a single pool of resources.
