14. Many companies use VMs to consolidate servers, enabling different services to run in separate VMs on the same physical machine.
15. Hosted approach provides partitioning services on top of a standard operating system and supports the broadest range of hardware configurations. In contrast.
16. Hypervisor architecture is the first layer of software installed on a clean x86-based system. Since it has direct access to the hardware resources, a hypervisor is more efficient than hosted architectures, enabling greater scalability, robustness and performance.
