What is Virtualization


In simple words, Creating multiple computer resources virtually in single hardware is called Virtualization.

Before Virtualization

  • Single OS image can run per machine at a time
  • Software and hardware tightly coupled 
  • Running multiple applications on the same machine and it may create conflict
  • Underutilized resources
  • Inflexible and costly infrastructure

After Virtualization

  • We can run multiple OS on a single machine
  • Hardware-independence of operating system and applications
  • One OS issue will not affect other OS and Application
  • We can manage OS and application as a single unit by virtual machines
  • Backup and restore is easy
