Virtualization is technology that lets you create useful IT services using resources that are traditionally bound to hardware. It allows you to use a physical machine's full capacity by distributing its capabilities among many users or environments. It's the same hardware, you're just using more of it more efficiently.

There are many reasons why people utilize virtualization in computing. Virtualization can increase IT agility, flexibility and calability while creating significant cost savings. Greater workload mobility, increased performance and availability of resources, automated operations – they're all benefits of virtualization that make IT simpler to manage and less costly to own and operate.

The 7 Types of Virtualization :

1. OS Virtualization—Virtual Machines.
2. Application-Server Virtualization.
3. Application Virtualization.
4. Administrative Virtualization.
5. Network Virtualization.
6. Hardware Virtualization.
7. Storage Virtualization.
