What is Cloud Computing?



What is virtualization?


In computing, virtualization refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, operating systems, storage devices, and computer network resources.





What is cloud computing?

                          The practice of using a network of remote servers hosted on the Internet
                          to store, manage, and process data, rather than a local server or a personal
                          computer.




Difference between Physical Vs Virtual Machine.


Benefits for Virtualization.
  • Without VMs: A single OS owns all hardware resources.
  • With VMs: Multiple OSes, each running its own virtual machine, share hardware resources.
  • Virtualization enables multiple operating systems to run on the same physical platform.
  • Easier Backup
  • Better testing
  • No vendor lock-in
  • Better disaster recovery
