Cloud computing allows businesses to run many different online environments from the same physical hardware. One “host” machine can run millions of “guest” virtual machines (VMs), each one with the ability to run entire operating systems and perform all of the functions of a physical computer. A hypervisor is software, firmware, or hardware that controls the guest operating systems and manages the activities on all of the virtual machines.
Understanding the Different Kinds of Hypervisors
Hypervisors, also called virtual machine managers, separate a computer’s applications and operating system from its physical hardware. The hypervisor allows multiple virtual environments to exist on the same physical machine while remaining isolated from one another. With more virtual machines and fewer physical machines, having a large infrastructure becomes drastically more affordable. One of the most important benefits of hypervisors is that if one of the many VMs crashes or is corrupted, recovery is quick and easy since it only affects that one VM, leaving the rest of your virtual infrastructure unscathed.
Two Types OF Hypervisors
There are two types of hypervisors: type-1 or type-2. Type-1 hypervisors, known as “native” or “bare metal” hypervisors, run directly on the host's hardware to control the hardware and manage guest operating systems. Type-2, also called “hosted” hypervisors, run on a conventional operating system with the guest operating systems running as a process on the host. The hypervisor layer separates the guest operating systems from the host systems, while running all of the virtualization processes.
Benefits of using our industry-standard hypervisors as part of a fully-managed virtual platform include:
- Extending the capabilities of existing servers and hardware
- Easily scalable technology for more or less virtual machines
- More efficient use of bandwidth and memory
- Allowing businesses to test new software and debug programs without disrupting the existing platform
- Improved security and reliability
- Lower costs
