Is there any difference between virtualization and cloud technologies or fundamentally both the same ?

Question

Is there any command in docker by which I can list down list of images/layers that have been used to construct a particular image ?

Answer 1

I was also looking into something similar Q. Google says to me "Virtualization is software that manipulates hardware, while cloud computing refers to a service that results from that manipulation.You can't have cloud computing without virtualization."

Virtualization software separates compute environments from physical infrastructures, so you can run multiple operating systems and applications simultaneously on the same machine.
