VM has own operating system that's why VMs are in heavy weight in nature.  HyperVisor *   creates VM on physical servers. Container Era: Containers are similar to VMs but they are light weight in nature because containers share machine's Operating system. Container RunTime Engine  *   help to creates container on physical servers. *HyperVisor: I t is known as vm monitor. It is a software that creates and run VMs.   Types of HyperVisor: HyperVisor- 1:   The hypervisor runs directly on the underlying host system.

Example are: Google compute Engine, Amazon EC2, Microsoft Azure VM 2.) PAAS(Platform as a services): PAAS is a mechanism for combining infrastructure as a services with an abstracted s
