How Many types of Virtualization technologies are there?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (C)

Virtualization technologies are best understood by looking at the main domains where resources can be virtualized. There are five broad types that cover the major ways this is done: server (compute) virtualization, desktop virtualization, network virtualization, storage virtualization, and application virtualization. Server virtualization lets you run multiple virtual machines on one physical server, improving consolidation and utilization. Desktop virtualization delivers user-desktop environments from centralized infrastructure instead of on each device. Network virtualization creates abstracted, programmable networks that can be managed independently of the underlying hardware. Storage virtualization pools multiple storage devices into a single, manageable virtual storage resource. Application virtualization runs software in isolated environments so the application is decoupled from the host OS, enabling portability and easier management. These five categories capture the primary areas where virtualization techniques are applied, even though many specific technologies exist within each domain (for example, containers sit under OS-level virtualization).
