Virtualization is a technique for separating services from the physical delivery that underlies the service. This is the process of creating a virtual version of something like computer hardware. It was originally developed during the mainframe era. This involves the use of special software to create virtual or software-created versions of computing resources rather than the actual versions of the same source. With the help of Virtualization, several operating systems and applications can run on the same Machine and the same hardware while increasing the utilization and flexibility of hardware.

In other words, one of the main cost-effective, hardware reduction, energy saving techniques used by cloud providers is virtualization. Virtualization is a technique, which allows sharing one physical example of a resource or application among many customers and organizations at a time. That is done by setting a logical name for physical storage and providing a pointer to the physical resource on request. The term virtualization is often synonymous with hardware virtualization, which plays a fundamental role in providing Infrastructure-as-Service-efficient (IaaS) solutions for cloud computing. In addition, virtualization technology provides a virtual environment for not only running applications but also for storage, memory, and networks.

Virtualization vs Cloud Computing:

Virtualization changes the relationship between hardware and software and is one of the basic elements of cloud computing technology that helps make full use of cloud computing capabilities. Unlike virtualization, cloud computing refers to the services that result from that change.

This illustrates the sending of shared computing resources, SaaS and services on demand through the Internet. Most of the confusion occurs because virtualization and cloud computing work together to provide various types of services, such as with private clouds.

Clouds often include virtualization products as part of their service package. The difference is that true clouds provide self-service features, elasticity, automatic management, scalability, and pay-as-you-go services that are not inherent in technology.

What types of virtualization are there?

Virtualization can take many forms depending on the type of application usage and hardware utilization. The main types are listed below:

1.Hardware Virtualization:

Hardware virtualization is also known as hardware-assisted virtualization or server virtualization runs on the concept that an individual independent hardware segment or physical server can consist of several smaller hardware or server segments, basically combining multiple physical servers to a virtual server running on the single primary physical server. Each small server can host a virtual machine, but the entire server group is treated as a single device with any process requesting hardware. Allotment of hardware resources is carried out by the hypervisor. Increased processing power is the key advantage and it results in the increase of application uptime and maximum utilization of hardware.

Subtype:

Full Virtualization – Guest software does not require any modification because the underlying hardware is fully simulated.

Emulation Virtualization – Virtual machines simulate hardware and become independent of its.No modifications are to be required by the guest operating system.

Paravirtualization – non-simulated hardware and guest software run their own isolated domain.

2.Software Virtualization

Virtualization Software involves making operations from various virtual environments on the host machine. This creates a computer system complete with hardware that allows the guest operating system to run. For example, this allows you to run Android OS on a host machine natively using the Microsoft Windows OS, using the same hardware as the host machine.

Subtype:

Operating System Virtualization – hosting multiple OS in the original OS

Virtualization applications – hosting individual applications in a virtual environment separate from the original OS

Service Virtualization – services  and hosting a specific process of a particular application

3.Memory  Virtualization :

Physical memory on different servers is collected into a single virtual memory pool. This provides the benefit of an enlarged adjacent working memory. You might already be familiar with this because some OS like Microsoft Windows OS allow a portion of your storage disk to function as an extension of your RAM.

Subtype:

Application-level control – The application accesses the memory collection directly

Operating system level control – Access to memory pools is provided through the operating system

4.Storage Virtualization:

Some physical storage devices are grouped together, which then appears as a single storage device. This provides various advantages such as homogenization of storage in storage devices of various capacities and speeds, reduced downtime, load balancing and better performance and speed optimization. Partitioning your hard drive into several partitions is an example of this virtualization.

Subtype:

Virtualization Blocks – Some storage devices are combined into one

File Virtualization – Storage systems provide access to files stored through multiple hosts

5.Data Virtualization:

This allows you to easily manipulate data because data is presented as an abstract layer that is completely independent of data structures and database systems. Reducing data input and formatting errors.

6.Network Virtualization:

In network virtualization, several sub-networks can be created on the same physical network, which may or may not is authorized to communicate with each other. This allows limiting the transfer of files across the network and increasing security and allows monitoring and identification of better data usage that allows network administrators to improve the network properly. It also increases reliability as interference in one tissue does not affect other tissues, and the diagnosis is easier.

Subtype:

Internal network: Allows one system to function as a network

External network: Consolidating multiple networks into a single network, or separating one network into several networks

7.Desktop Virtualization:

This is probably the most common form of virtualization for every regular IT employee. The user’s desktop is stored on a remote server, allowing users to access their desktop from any device or location. Employees can work comfortably from the comfort of their home. Because data transfer occurs through a secure protocol, the risk of data theft is minimized.

8. Server Virtualization

Here is the practice of earning accessible the resources of physical servers into distant users. It’s likely to get it done by installing virtual server software onto the server that then lets it act as numerous servers on demand. This kind of Virtualization is prevalent as it prevents users from having to manage complex server systems.

Server virtualization is just one of those fastest-growing regions of the cloud. It’s used to provide immense resources to businesses that need the processing capacity but don’t always have the funds to spend on the appropriate server tools. AWS is a prominent example of the company, offering an extremely flexible and robust infrastructure that allows its customers access to various information processing services at a really reasonable cost.

9. Application Virtualization

Software virtualization in cloud computing abstracts the application layer, separating it from the working system. This way, the application can run in an encapsulated type without being dependant upon the operating system underneath. Along with providing a level of isolation, an application made for one OS could run on a completely different operating system.

Key Concept

If a company decides whether to implement this technology in the company’s IT landscape, we recommend making an in-depth analysis of its specific needs and capabilities, which are better handled by specialists who can handle costs, scalability requirements and security needs and implement sustainable development.

But also remember that all these techniques and services are not omnipotent or all-inclusive solutions. Like any technology, tool, or service that is adopted by a business, things can always change.
