Power of Virtualization!

Virtualization is simply abstraction of computer resources in order to share or use them by multiple virtualized instances of different OSs. It can be easily understood in following diagram:

Advantages of Virtualization

1. Zero downtime maintenance

2. Instant provisioning

3. Virtual hardware supports legacy operating systems efficiently

4. Dynamic resource sharing

5. Security and fault isolation

6. Business continuity, backups, and automated restoration

7. Virtualization offers major savings in data center operations.

8. Virtualization makes possible significant reductions in the costs of managing data centers, with simplification  of systems management tasks.

9. Virtualization offers increased redundancy for delivery of high performance and high availability services.

1. Administration Cost

2. Green initiative by reducing heat dissipation at huge servers

3. Base hardware utilization up to maximum level (80 to 90%)

4. Scale up and scale down as per the requirements of resources that can be hardware or software.
