What are the Different Types of Virtualization in Cloud Computing?

The streamlined efficiency of IT landscapes, improved operation time, optimized hardware spending and facilitated troubleshooting are among the valuable advantages that attract many businesses to virtualization. Recently, it has been becoming a framework for cloud and mobile computing, Big Data and social media — technologies that are predicted to account for 98% of IT expenditures by 2020.

The vibrant adoption of cloud computing virtualization has given rise to different types of virtualization,each related to specific IT workloads and assets.

Desktop Virtualization

Basic users that have a question “What is virtualization in cloud computing?” better get started with an insight into this type, as many of them already use it subconsciously. Irrespective of the industry, a growing number of businesses apply virtualization on a daily basis, as this technology enables easy access to user desktops from any appliance and location. Also, this method is a workaround in cases when devices fail or are lost, as user data remains available from another appliance.

Hardware Virtualization

Hardware or server virtualization refers to hard infrastructures that are shifted to virtual landscapes. The reason why many companies abandon their traditional equipment-based facilities in favor of cyber ones is significant cost optimization. Typically, businesses that own servers use 15% of their capacity at best at quite a high cost.

That is why, to allocate corporate funds efficiently, companies opt for server virtualization in cloud computing. They launch a required quantity of virtual machines and provide them with access to in-house resources.

In most of the cases, servers that virtualize hardware belong to third-party suppliers that monitor and maintain their operational state. That is why this technology not only reduces equipment-related expenditures, but also enhances and streamlines the deployment, availability and performance of workloads.

The required extent of facility simulation and functionality modification distinguishes the types of hardware virtualization, such as:

  • Full. It necessitates thorough server imitation that does not stipulate any modifications to the software.
  • Emulation. Under this type, virtual machines imitate hardware and then become independent. No modification of the operating system is required.
  • Paravirtualization. This type does not involve asset simulation and software alteration, but simulates and modifies interface functionality.

Software Virtualization

Performance and compatibility issues are permanent companions of corporate workloads that execute on different operating systems. Software that has been converted into a virtual form helps address this challenge as it enables workload operations on host machines that have their own hard infrastructure. To support customers’ operating systems, host machines create full-fledged platforms that possess all of the required functionality to refine software performance.

This type can be broken down into three subtypes that are determined in accordance with the sorts of  corporate workloads that need to be hosted virtually: applications, operating systems or services.

Network Virtualization

To enable the efficient operation and smooth integration of a company’s networked resources and assets, a growing number of businesses have been disassociating their in-house connections from the underlying hard infrastructure. After all the in-house software, workloads and facilities have been consolidated into an integral system, they perform much more efficiently than a network that consists of silo components.

Guided by how networks incorporate assets and systems, two different types of virtualization exist. Internal nets fuse together the components of one system and external ones aggregate intranets or random components into integral units.

Data Virtualization

Virtual data is an efficacious tool for companies that require facilitated data handling. Virtualized information exists as a database- and structure-independent layer, and to manipulate this information, applications do not require source-related formatting, location and other technical details.

This information is left in place and can be accessed in a real-time manner, which eliminates data extraction, conversion and loading procedure that often causes format failures and data entry errors.

Random Access Memory Virtualization

Businesses visualize their segmental physical memory to aggregate it into one repository. They launch enlarged memory pools that serve as message layers, high-speed caches or shared storage budgets and enable access for operating systems and workloads.

The manner in which workloads can access the memory lay the foundation for two related types of virtualization in cloud computing. An application-level access enables direct access to RAM, while an operating system-level one allows turning to memory pools only via operating systems.

Storage Virtualization

To homogenize repository, enhance uptime, balance the load and improve productivity, companies make their storing appliances operate in a virtual manner as a unit. They can virtualize their in-house disks, tapes and other media in two manners: in relation to blocks and individual files.

Virtualized block storages allow accessing various devices regardless of their location and structure, based on the separation of a logical repository from a physical one. In cases of a file-based process, storage provides access to files that are kept on numerous hosts, which removes dependencies between data and their physical location. As a result, companies manage their storage in an efficient manner and are able to migrate files seamlessly.

Make the Most of the Virtualization of Cloud Computing

Regardless of how many types of virtualization companies can apply in their specific IT environments, they should perform this process correctly to take full advantage of the possibilities this technology offers. Security is another important concern, as the process manipulates vulnerable corporate data and workloads.

To enhance the operation of an in-house IT landscape, as well as to reduce related risks and threats, we highly recommend relying only on established software service providers. Only reliable experts with the wealth of domain experience will skillfully guide you through the ins and outs of this process to help you gain the maximum benefits.
