What are Hypervisors?
Hypervisors are important software that enables virtualization. The virtualization layer created by the hypervisor separates CPU / processor, RAM, and other physical resources from the virtual machine it creates. It abstracts the guest computers and the operating system they are running from the actual hardware. The machine on which you install the hypervisor is called the host machine instead of the guest virtual machines that run on it.
This is part of a private cloud that manages virtual machines. It is a part of a program that allows multiple operating systems to share the same hardware. Any operating system can use all hardware (processors, memory) if no other operating system runs. This is the largest hardware available in the cloud operating system. Still, the hypervisor controls and allocates the percentage of hardware resources to each operating system to get what they need and do not interfere with each other.
A hypervisor allows you to run a variety of guest computers on a physical host computer. This helps maximize the benefits of computing resources such as memory, network bandwidth, and CPU cycles. In this blog, we’ll briefly look into the types of Hypervisors, but you should sign up for a Cloud Computing Course if you are interested in learning more.
Types of Hypervisors in Cloud Computing
There are two types of Hypervisors in Cloud Computing:
Type I Hypervisor:
The Type I hypervisor runs directly on the host’s hardware to monitor the hardware and guest virtual machines. This is called bare metal. No prior software installation is usually required, and instead, install it directly on your hardware. This type of hypervisor is typically powerful and requires a lot of expertise to function properly. In addition, Type I hypervisors are more complex and have specific hardware requirements to run properly. For this reason, it is primarily the choice of IT companies and data center computing. Examples of Type I hypervisors are Xen, Oracle VM Server for SPARC, Oracle VM Server for x86, Microsoft HyperV, and VMware ESX / ESXi.
Type II Hypervisor:
A Type II Hypervisor is also known as a hosted hypervisor because it is often installed on top of an existing OS. You can hardly perform more complex virtual tasks. People use it for basic development, testing, and emulation. If a vulnerability is found in the host operating system, all running virtual machines could be compromised. For this reason, Type II hypervisors cannot be used for data center computing. These are designed for end-user systems where security is less important. For example, a developer can use a Type II hypervisor to boot a virtual machine and test it before the software product is released. Some examples of type II hypervisors are Virtual Box, VMware Workstation, Fusion.
To get used to the hypervisor, you need to understand cloud computing. Cloud computing is the provision of on-demand computing resources over the Internet. These resources include data storage, computing power, applications, physical servers, virtual servers, development tools, network capabilities, and more. Cloud computing platforms help businesses build their entire infrastructure across the Internet, not their data centres. The cloud computing course duration depends on the respective course.
