Virtualization is the creation of virtual servers, infrastructures, devices and computing resources. Virtualization changes the hardware-software relations and is one of the foundational elements of cloud computing technology that helps utilize the capabilities of cloud computing to the full. Virtualization techniques allow companies to turn virtual their networks, storage, servers, data, desktops and applications.
Types of Virtualization in Cloud Computing
Operating System Virtualization
a. Operating System Virtualization
In operating system virtualization in Cloud Computing, the virtual machine software installs in the operating system of the host rather than directly on the hardware system.
The most important use of operating system virtualization is for testing the application on different platforms or operating system. Here, the software is present in the hardware, which allows different applications to run.
b. Server Virtualization
In server virtualization in Cloud Computing, the software directly installs on the server system and use for a single physical server can divide into many servers on the demand basis and balance the load.
It can be also stated that the server virtualization is masking of the server resources which consists of number and identity. With the help of software, the server administrator divides one physical server into multiple servers.
c. Hardware Virtualization
Hardware virtualization in Cloud Computing, used in server platform as it is flexible to use Virtual Machine rather than physical machines. In hardware virtualizations, virtual machine software installs in the hardware system and then it is known as hardware virtualization.
d. Storage Virtualization
In storage virtualization in Cloud Computing, a grouping is done of physical storage which is from multiple network storage devices this is done so it looks like a single storage device.
It can implement with the help of software applications and storage virtualization is done for the backup and recovery process. It is a sharing of the physical storage from multiple storage devices.
Benefits of Virtualization
There are following benefits of virtualization in cloud computing;
Security has been the advantageous concern for adopting virtualization.The security is served through firewalls that prevent from any unreliable access and preserve the data safe and confidential.
In addition to that,
The firewalls provide extra security from any sort of cyber threats and virus attacks.The protocols consist of end to end encryption, saving data automatically from other risky threads, and
Users can virtualize their data and make backups of the same data on another server when needed.
With the deployment of virtualization, users can work efficiently as the working process is very streamlined and agile. Presently, the employed network switch is easy to use, flexible and saves time.
Virtualization is also helpful in troubleshooting technical errors, occurring in any of the connected devices. It eradicates the issues of retaining or recovering lost data due to corrupted or crashed devices, and therefore promotes ROI and saves time.
This is the most prime reason to choose virtualization rapidly as with this technique companies can manage additional expenditure on physical devices and servers.
Being active with a virtual environment, data can be gathered on virtual servers. It also reduces the rigorous use of electricity (that has been a concern if several physical devices and services are being used at the same time), lowering bills while executing the numerous components of an operating system and applications over the users and companies network.
Flexible data transfer:
The data can be transferred to virtual servers anytime and also be retrieved due to this users or cloud providers need not to waste time in finding out hard drives to discover data.
With the implementation of virtualization, it has become easy to allocate the required data and transfer them to the appropriate authorities. Moreover, there is no limitation of data transfer and can be transferred.
Remove system failure risks:
While performing any function, it often happens that the system might malfunction in critical timing such that this system failure could be adverse for a company’s resources and also deteriorate its reputation.
This system failure can be protected with virtualization as users could perform the same task simultaneously over multiple devices, and the accumulated data can also be retrieved anytime with any device.
Along with it, the server has the two working sides that makes data accessible at any point of time, if one primary server goes down, the secondary server is there to deliver access to the users when they demand to retrieve data for their use.
Leveraging virtualization and cloud computing for your organization
Today, many major businesses are hiring IT professionals to upgrade their computing models. Many qualified systems engineers are pioneering strategies that help migrate files from server environments to cloud networks.
To leverage both cloud computing and virtualization side by side in an IT environment, you’ll need an in-depth knowledge of both technologies. If you’re an IT professional, or you’re simply looking to familiarize yourself with the industry’s employment opportunities, cloud computing training is the quickest way to get there. Complete courses at your own pace, through hands-on training led by real instructors from around the world. After you finish your cloud training, you’ll be ready to pursue virtually any career in the cloud computing space — equipped with a certification accepted industry-wide.
Virtualization is a method of creating computer-generated versions of servers, apps, data centers, and other forms of hardware that operate identically to their actual counterparts using software. It is the process of producing a virtual representation of a physical object, such as computer hardware. It was created back when mainframe computers were still in use. It entails the use of specialized software to generate a virtual or software-created version of a computing resource rather than the real thing. Virtualization allows different operating systems and applications to operate on the same machine and hardware at the same time, enhancing hardware usage and flexibility.
In other words, virtualization is one of the most cost-effective, hardware-saving, and energy-saving approaches employed by cloud providers. Virtualization allows several consumers and organizations to share a single physical instance of a resource or application at the same time. This is accomplished by giving a physical storage a logical name and supplying a pointer to that physical resource on demand.
Virtualization is frequently used interchangeably with hardware virtualization, which is critical for delivering Infrastructure-as-a-Service (IaaS) solutions for cloud computing. Virtualization technologies also create a virtual environment for storage, memory, and networking, in addition to executing applications.
From outsourcing the hardware used, and curtailing the implementation of specific sources, to removing additional costs of energy, virtualization assists in a very proficient way such as it provides augmented security, competence, and cost convenience, however it might not work for each user. Depending on the need of virtualization type, a user can seek a service provider, rendering appropriate tools for maintaining and controlling a number of resources that will be time saving and cost effective in order to make the process more adequate.
