What is Virtualization

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
