| Virtualisation in a Nutshell | | | | Top 5 reasons to adopt Virtualisation software |
| Virtualisation is a software technology which | | | | - Server Consolidation and Infrastructure Optimisation: |

| Today's powerful computer hardware was originally | | | | - Improved Operational Flexibility & |
| designed to run only a single operating system and a | | | | Responsiveness: Virtualisation offers a new way of |
| single application, but virtualization breaks that bond, | | | | managing IT infrastructure and can help IT |
| making it possible to run multiple operating systems | | | | administrators spend less time on repetitive tasks |
