Hardware Virtualization in Cloud Computing – Working, Types, Benefits

Hope you are enjoying our Cloud Computing tutorials, last we ended our session on Virtualization in Cloud computing. Today, we are going to study Hardware Virtualization, one of the types of Virtualization. In this article, we will explore the working, types and benefits.

Introduction to Hardware Virtualization

Hardware Virtualization in Cloud Computing – Working, Types, Benefits

1. What is Hardware Virtualization?

Virtualization means creating a virtual platform of something, which will include virtual computer hardware, virtual storage devices, and virtual computer network.

In hardware virtualization, software called hypervisor is used. With the help of hypervisor virtual machine, software embedded into the hardware component of the server. The work of hypervisor is that it manages the physical hardware resource which is shared between the customer and the provider.

Hardware virtualization can be done by extracting the physical hardware with the help of the virtual machine monitor (VVM). There are several extensions in the processes, which help to accelerate virtualization activities and boost the performance of hypervisors. If this virtualization is done for server platform it is known as server socialization.

2. How Hardware Virtualization in Cloud Computing Works?

hypervisor creates an abstraction layer between the software and the hardware in use. After the installation of a hypervisor, virtual representations take place such as virtual processors. We cannot use physical processors after installation. There are several popular hypervisors such as VMware’s vSphere, based on ESXi, and Microsoft’s Hyper-V.

In this system, multiple VMs can host at a time, but every VM logically isolated from each other. This is because of the security reasons. One of the security reasons is a Malware attack or the crash of VM. Because of this, the other VMs will not get affected. If multiple VMs use, the efficiency of the system will increase simultaneously and the overall performance will be better. So, this will leads to the fact that this improved heartbeat utilization provides various benefits and supports system while reducing the number of servers which will save money.

3. Types of Hardware Virtualization

This is the list of hardware virtualization in Cloud Computing:

  • Full Virtualization
  • Emulation Virtualization
  • Para-Virtualization

i. Full Virtualization

In full virtualization, there is no need for any modification to run any application. In addition, the hardware architecture completely simulates, which benefits the guest software. There is an environment, quite similar to an operating system in a server.

With the help of full virtualizations, the administrators allow running a virtual environment change to its physical counterpart. With the help of full virtualization, the administrators can combine the new and the existing system for something efficient. So, it should be compatible with the newer system.

ii. Emulation Virtualization

In emulation virtualization, hardware simulates by the virtual machine and it is independent. Here, the guest operating system does not require any other modification. In this virtualizations, computer hardware as architectural support builds and manages a fully virtualized VM.

iii. Para-virtualization

In paravirtualization, the hardware not simulates and the guest software runs its isolated system. It is not necessary to simulate the hardware, but it utilizes an API which modifies the guest operating system. The hypervisor provides a various command, which is sent from operating system to the hypervisor and is called hypercalls. These hypercalls are further use for memory management.

4. Benefits of Hardware Virtualization

It’s time to talk about the advantages of Hardware Virtualization in Cloud computing:

Hardware Virtualization Advantages

Advantages of Hardware Virtualization

i. Economical

These virtualizations are compatible with large scale as well as small-scale industries. As most of the amount is spent on hardware, the hardware virtualization eliminates this cost and benefits the customer. It also increases the lifespan of the existing hardware which reduces the energy costs.

ii. Efficient backup and recovery

As the disaster is unexpected and the data can be destroyed in seconds. Here, virtualizations make recovery much easier and accurate with less manpower while using very fewer resources.

iii. Efficient its operations

It can provide an easier way for the IT staff to install and maintain the software rather than maintaining hardware. Everything can be done with the help of a computer and its professional will do it with less downtime, quicker recovery, and fewer outages.

iv. Disaster recovery in hardware virtualizations

In the cloud there a situation where continuous operation is done and a disaster recovery plan should be there which can provide surety that the performance and maintenance are met after the retrieval of the data. Disaster recovery plan in hardware virtualization involves the protection of both hardware and the software and this can be done by various methods.

v. Tape backup

In this method, data stores offsite and the data recovery can be difficult and time-consuming. If a customer is restoring the latest copy of the data then he will get most in the backup. There is a requirement of a backup device and ongoing storage material.

v. File and Application Replication

Here, the data replicated on the separate disk and UP control software requires for application and data file storage replication which can be on the same side. This method basically uses for database-type applications.

vi. Hardware and Software Redundancy

This method provides a duplicate hardware and software application which situates at two different geographic areas. This method has the highest level of disaster recovery protection and virtualization solution.

5. Conclusion

Hardware virtualization is evolving very quickly and it is gaining popularity in server platforms. The basic logic behind hardware virtualization is to integrate many small services into a large physical server so that it can use more effectively and providing the service efficiently. Here, the operating system which runs on the physical server convert into an operating system which works inside the virtual machine. The operating system which is working on the machine consists of its own processor, memory, and various other components.
