Hardware Virtualization in Cloud Computing

Types of Hardware Virtualization

There are mainly three types of Hardware Virtualization:

Full virtualization

It is underlying Hardware that is fully simulated. The Guest software does not require to perform any modifications to run their applications. With full virtualization, the administrators can combine the new and the existing system for something efficient. So, it should be compatible with the unique design.

Emulation Virtualization

In this type of Virtualization, the virtual machine simulates the Hardware, hence becoming independent of it. In this Virtualization, the guest operating system does not need to perform any modifications.

Para-virtualization

The Hardware is not simulated in Para-Virtualization. Here, the Guest software must run its own isolated domains. The hypervisor provides various commands sent from the operating system to the hypervisor and is called hypercars. These hypercars are further used for memory management.

So now, since you get a brief idea of how Hardware virtualization operates, It’s time to understand the advantages of Hardware virtualization in cloud computing.

Advantages

The main advantages of Hardware virtualization in cloud computing are illustrated below:

• Lower Cost
  These virtualizations are compatible with large-scale and small-scale industries. Multiple OS can exist in single hardware because of server consolidation, the cost decreases. It also increases the lifespan of the available hardware, which reduces energy costs.
• Efficient resource utilization
  It can provide a better way for the IT staff to install and maintain the software rather than maintaining hardware. Everything can be operated using a computer, and its professionals will do it with less downtime, quicker recovery, and fewer outages.
• Increase IT flexibility
  Using virtualization, The rapid development of hardware resources became possible, And we also managed consistency by using it.
• Advanced Hardware Virtualization features
  With the improvisation of modern hypervisors, highly complex operations maximize the abstraction of hardware & ensure maximum uptime. This technique helps migrate an ongoing virtual machine from one host to another host dynamically.

We will close the article now with faqs since you get the overall idea of Hardware virtualization.

FAQs

1. How can hardware virtualization be achieved in cloud computing?
   Hardware virtualization can be achieved by extracting the physical hardware with the help of the virtual machine monitor (VVM). There are several extensions in the processes which help accelerate virtualization activities and boost the performance of hypervisors.
2. Can virtualization be implemented in hardware without a hypervisor?
   OS virtualization virtualizes hardware at the OS level to create multiple isolated virtualized instances to run on a single system. Since OS virtualization will have the guest OS use the same running OS as the host system, this process is done without using a hypervisor. 
3. Which components are needed to support hardware-based virtualization?
   There are mainly three elements required to support hardware-based virtualization, the CPU, memory, and network I/O capacity. They're all critical for workload consolidation.
4. What hardware is used for virtualization?
   Hardware virtualization is accomplished by abstracting the physical hardware layer using a hypervisor or VMM (Virtual Machine Monitor).
5. Does hardware virtualization improve performance?
   It does not affect regular program performance or gaming performance. CPU virtualization provides a computer to run a virtual machine that allows running in a different OS installed on the computer by using some virtualization software like Virtualbox.
