Virtualization in Cloud Computing: The 6 Types

Virtualization in cloud computing

Virtualization is defined as building a virtual environment of the physical aspects of a system’s infrastructure. A virtual machine(VM) is run over an existing operating system and hardware resource of another system. The virtual machine and hardware are separated logically, even when they are physically in close proximity and the interaction between them is protected by several layers of security. Here we will read about Virtualization in Cloud Computing

The virtual machine running on top of the hardware is called the ‘guest machine’, and the hardware and OS of the VM is called the ‘host machine’. 

Cloud computing has given a fresh impetus to virtualization. Cloud Computing is the various data centers available over the internet for the users. This network of remote servers that store, manage and process data has ensured the optimum usage of physical resources while providing a lot of flexibility to the users. 

Most IT businesses have a physical server dedicated to a specific application which leads to underutilization of the server’s capacity resulting in higher IT and operational costs. 

Businesses are opting for Cloud virtualization for:

  • Space optimization- A Physical server takes space and requires frequent maintenance and updates that need to be done one after the other. Virtualization allows installation, updation, and maintenance of VMs virtually saving time and labor.
  • Operating cost reduction-  Consolidation of applications in a virtualized environment means fewer physical customers and reduced costs for the business
  • Datacenter management- With virtualization data centers become available, scalable, and secure.
  • Effectively minimizing downtime- When a problem occurs with the physical server, it may take hours or days to get it fixed however with a virtualized environment it becomes easier to provision and deploy, clone the affected virtual machine and fix it in minutes.
  • Speeding up the provisioning process- With no need to handle actual physical hardware components, virtualization allows companies to use pools of CPU and Memory as hardware components functioning as a server without having to actually go out and buy one.
  • Increasing responsiveness and resource availability
  • It is a greener option with a lesser carbon footprint

There are 6 types of virtualization in cloud computing:

Application virtualization

This allows a user to access an application virtually. The server stores all the information and the characteristics of the application but can be run remotely using the internet. It also eases and expedites the rollout of an application in an environment and helps in upgrading and supporting them effectively. 

Network virtualization

This allows the running of multiple virtual networks with each having a separate control and data plan. It provides a facility to create and provision virtual networks—logical switches, routers, firewalls, load balancer, Virtual Private Network (VPN), and workload security in the shortest duration possible. 

Desktop Virtualization

This allows users to access their desktops remotely, users who wish to use operating systems different than the windows server can do so effectively by using desktop virtualization. The obvious benefits include portability, easy software installation, and patches. 

Storage Virtualization

It is an option that provides an isolated, secure, and robust storage solution across multiple networks virtually. All this can be achieved from as little as one storage component. Even when there is a breakdown of underlying systems, it ensures smooth and continuous operation. 

Server virtualization

When different operating systems need to run on the same physical server, it allows that by using VMs where each system can operate in an isolated manner.

Data Virtualization

As the name implies, it grants data access to interested stakeholders remotely. Large amounts of data can be stored and accessed using it.
