Today, we will let to know about the Different Types Of Virtualization In Cloud Computing
Virtualization is the process of accessing a virtual instance of a computer system in a layer abstracted from the actual system. Most commonly, it refers to access multiple operating systems on a computer system at the same time. To the applications accessing on the top of the virtualized device, it can appear as if they are on their own dedicated device, where the operating system, libraries, and other programs are unique or special to the other virtualized system and disconnected to the host operating system which sits under it.
Different Types Of Virtualization In Cloud Computing
Virtualization is used to be a technique, which commands to share a single/solo physical instance of a data or an application among multiple clients and companies at one time. It is done by setting a unique name to physical storage and providing a pointer to that physical resource on choice. The term virtualization is oft the same with hardware virtualization, which plays a crucial role in efficiently delivering Infrastructure-as-a-Service (IaaS) solutions for cloud computing.
It is the way of developing a virtual platform with the help of virtualization software. These software’s acts as a layer or display sheet between the primarily designed system and the secondary designed system or virtually designed systems.
The Term which we are using here “Virtualization” was invented in the 1960s, as a method of logically dividing the system data provided by mainframe computers between different applications.
Benefits of Virtualization
- It is a more flexible and efficient allocation of resources.
- It enhances developer productivity.
- It lowers the cost of IT infrastructure.
- Both Remote access and rapid scalability.
- High level of availability and fast recovery.
- Pay per use of the IT infrastructure on demand.
- It enables the running of multiple operating systems.
Different Types of Virtualization
1. Application Virtualization
Application virtualization helps the user to have easy access to an application from a server. The server stores all personal data and other characteristics of the application or, but can still run on a local workstation with the help of internet. Example of this would be an if a client, who needs to run two different versions of the same application. Technologies which uses application virtualization are hosted and packaged software.
Application virtualization can be an effective way to improve and maintain they’re published/posted applications. The major benefit is to have that IT administrators to get an application to a server, rather than multiple desktops, making it easier to edit applications and Do patches centrally.

Advantages of Application Virtualization
- It helps to make it possible to run applications that might have legacy issues (developed for older OSes).
- It makes user access for cross-platform operations (running Windows applications on Android, iOS, macOS, and Chromium).
- It removes the problems with other virtualized applications (for example, some applications don’t like each other).
- It can be accessible to a user, to run more than one instance of an application (if not virtualized, some will detect that an instance is already running and won’t start a new one).
Disadvantages of application virtualization:
Application virtualization comes with challenges as well. Not all applications are suited to virtualization. For example, many kinds of stuff like graphics-intensive applications can slow down (lag) during the rendering process. In addition, a steady and reliable connection to the server is required to provide the client with a solid UX with the applications. Some software requires device drivers and 16-bit applications for accessing the memory.
2. Network Virtualization
The ability to run multiple/several virtual networks that each has a separate or all different control and data plan. It co-exists together on top of one physical connection. The content can be responded by an individual or single parties that potentially confidential to each other.
Network virtualization provides a feature to create and provision virtual networks—logical switches, routers, firewalls, load balancer, Virtual Private Network (VPN), and workload security within days or even in weeks.
Network virtualization is the method of splitting up network resources into different bandwidth channels that are each independent from each and every one another, and that can be assigned and reassigned to servers or other network devices. The main reason which is issued to optimize the speed, reliability, and flexibility of the network or setup of the work.
It is the partitioning of physical server resources, such as memory, I/O, storage, and CPU. The data are confined to the physical structure of a single or solo device and share little/less if any, distributed state. Virtualization is the skill that can be used to separate, abstract and decouple the physical topology from a ‘logical’ or ‘virtual’ topology by using encapsulated tunneling. The logical network topology is often the same as an ‘Overlay Network’.
The virtualization of the network can be categorized as either external or internal. The Basic use of External network virtualization is the adding of one or more local networks or fraction of networks into a big system “virtual” network with the impressive goal of improving the efficiency of a large network or data center. Its two key components are the virtual local area network (VLAN) and the network switch. Using these two together, system administrators can configure systems that are physically attached to the same local network into many different virtual networks.
Most importantly, the basic use of Internal network virtualization is a connection or a network that confined to a single/solo device or system and provides network functionality to the different VMs using a single system or server. However few times we observed that it is also referred to as network in a box, and it improves the overall efficiency of a single system by isolating the different virtual environments or conditions and access allowance them to communicate or have a connection over a virtual network interface. The issued type is most commonly/easily seen on the work station versions of VMware and Parallels.
Desktop virtualization allows the users’ OS to be remotely stored on a server in the data center. It allows the user to access their desktop virtually, from any location by a different machine. Users who use specific systems other than Windows Server will need to have a virtual desktop. The most important advantages of desktop virtualization are to behave user mobility, portability, easy management/conductivity of software installation, updates, and patches.
The Term “Desktop virtualization” is a precious and much valuable skilled platform and solves many as business problems. With the many advantages which are, Desktop virtualization has to command for an environment.
Desktop Virtualization Categories
- Cost Savings
From an IT perspective, virtual desktops help reduce the time it takes to provision new desktops, and they also help to decrease desktop management and support costs. Experts estimate that maintaining and managing PC hardware and software accounts for 50-70% percent of the total cost of ownership (TCO) of a typical PC. Companies often turn to virtual desktops to cut these IT labor costs.
- Simplified Management
Though all the work is accordingly done, stored and secured, basic virtual desktops remove/kills the need to install, update and patch, back up files and scan for viruses on individual client devices. The term “Desktop virtualization” commands/orders to the management of software assets.
- Enhanced Security
The Virtual desktops give higher security to a company because clients aren’t carrying around confidential company data on a personal device that could easily be lost, stolen or tampered with. Though in the companies such as healthcare, where the issue is to privacy rules & regulations is of paramount importance, virtual desktops give medical personnel access to patient records without concerns about confidential information being downloaded. Rather the user data is backed up safely and regularly, desktop virtualization also provides data integrity benefits.
- Increased Productivity
The term “virtual desktops” allow the client to access software and docs from multiple systems, including other computers, laptops, tablets, and smartphones. It helps to increases production by giving workers to access necessary data/records from anywhere. The main issue, whether clients are in another building, another state, or halfway across the globe, a virtualized desktop allows them to be productive in any environment. Plus, if the client’ is defective/damaged, they can merely log in from another device or system and continue working because the data was not stored locally. The basic Virtual devices also reduce the downtime the IT department needs to manually install new software or download software updates. This increases the productivity of all clients.
The term “Storage virtualization” is a collection of servers that are controlled by a virtual storage system. The systems aren’t aware of exactly where their software is stored, and instead, function more like worker bees in a hive. It updates managing storage from multiple possible and utilized as a single repository. The storage virtualization software maintains easy commands over here, constant and regular performance and a continuous suite of advanced functions despite updates, break down and differences in the underlying stuff.
The storage systems can give one of the stuff like, block accessed storage, or file accessed storage. Block access is mainly sent over Fibre Channel or frequency, iSCSI, SAS, FICON or other protocols. The File transfer is often provided using NFS or SMB protocols.
The Main Storage Virtualization can be implemented by using software application.
Three important reasons for storage virtualization
- All the Improved storage management in a heterogeneous IT environment
- To have better availability and approximation of downtime with automated management
- To have a Better storage utilization
Storage virtualization can be checked to any stage of a SAN. The virtualization techniques can also be accessible to check to all different and unique storage functions as of physical storage, RAID groups, logical unit numbers (LUNs), LUN subdivisions, storage zones and logical volumes, etc.
So All the public, you are having a few issues so you can clear all your doubts over here, that there are many reasons why people utilize virtualization in computing. To all the system users, the most common use is to be able to run software meant for a unique operating system without having to switch or reboot into a different system. The issue for admins of servers or system, virtualization also offers the power to run many different operating systems, but perhaps, more importantly, it offers a trick to segment a large setup into many smaller parts, allowing the server to be used more softly and easily by a number of different users or with different needs. It makes easy for isolation, keeping applications running inside of a virtual device safe from the processes or ways that it taking place in another virtual device on the same host.
