What is virtualization

Virtualization is the process of creating a virtual version of something, such as an operating system, server, storage device, or network resources. It involves using software to create a virtualized environment that emulates the behavior of a physical environment. This virtual environment can be used to run multiple instances of an operating system or application on a single physical machine, which can improve resource utilization, reduce costs, and increase flexibility and scalability.

Virtualization can be achieved through various technologies, such as hypervisors, containers, and emulation. Hypervisors are software that allows multiple operating systems to run on a single physical machine, each in its own virtual machine. Containers, on the other hand, allow applications to run in a lightweight, isolated environment, sharing the host operating system kernel. Emulation involves running software or hardware on a different platform or architecture than it was designed for, typically using software emulation to simulate the behavior of the original hardware.

Virtualization has many benefits, including improved resource utilization, increased flexibility, and reduced costs. It is widely used in data centers, cloud computing, and software development environments, among other applications.

There are several types of virtualization:

Full Virtualization: This type of virtualization enables multiple operating systems to run on a single physical server. Each virtual machine (VM) runs its own operating system and applications, as if it were a separate physical computer. Examples of full virtualization software include VMware and Microsoft Hyper-V.

Para-Virtualization: In this type of virtualization, the guest operating system is modified to allow for communication with the host operating system, which results in better performance compared to full virtualization. Examples of para-virtualization software include Xen and Virtuozzo.

Operating System-Level Virtualization: This type of virtualization enables multiple applications to run on a single operating system instance. Each application runs in its own isolated environment, with its own resources and security settings. Examples of operating system-level virtualization software include Docker and LXC.

Network Virtualization: This type of virtualization enables the creation of virtual networks that are logically separated from the physical network. Network virtualization allows for more flexible and efficient network management. Examples of network virtualization software include VMware NSX and Microsoft Hyper-V Network Virtualization.

Storage Virtualization: This type of virtualization enables the pooling of physical storage resources, such as hard drives and solid-state drives, and presenting them as a single virtual storage device. Storage virtualization allows for better utilization of storage resources and simplifies storage management. Examples of storage virtualization software include VMware vSAN and Microsoft Storage Spaces.

Application Virtualization: This type of virtualization enables applications to run in an isolated environment, separate from the underlying operating system. This allows for greater compatibility across different operating systems and versions, and also simplifies application management. Examples of application virtualization software include Citrix XenApp and VMware ThinApp.

Desktop Virtualization: This type of virtualization enables multiple virtual desktops to run on a single physical computer. Each virtual desktop has its own operating system, applications, and settings, allowing for greater flexibility and security. Examples of desktop virtualization software include VMware Horizon and Microsoft Virtual Desktop Infrastructure.

Presentation Virtualization: This type of virtualization enables the delivery of remote applications to client devices over a network. The applications run on a server, but are presented to the user on their local device as if they were running locally. This allows for greater flexibility in application delivery and simplifies management. Examples of presentation virtualization software include Citrix XenApp and Microsoft Remote Desktop Services.

GPU Virtualization: This type of virtualization enables multiple virtual machines to share a single physical GPU (graphics processing unit). This is useful for running graphics-intensive applications, such as 3D rendering and machine learning, in virtualized environments. Examples of GPU virtualization software include NVIDIA GRID and AMD MxGPU.

Mobile Device Virtualization: This type of virtualization enables multiple virtual mobile devices to run on a single physical device. Each virtual mobile device has its own operating system and applications, allowing for greater flexibility in testing and development. Examples of mobile device virtualization software include Genymotion and VMware Workspace ONE.

Disaster Recovery (DR) Virtualization: This type of virtualization enables organizations to replicate their entire IT infrastructure, including servers, storage, and networking, to a remote location for disaster recovery purposes. The replicated environment can be brought online in the event of a disaster, allowing business operations to continue. Examples of DR virtualization software include VMware Site Recovery Manager and Microsoft Azure Site Recovery.

Cloud Virtualization: This type of virtualization enables the creation of virtualized resources, such as servers, storage, and networking, in a cloud environment. Cloud virtualization allows for greater flexibility and scalability, as resources can be provisioned and de-provisioned on demand. Examples of cloud virtualization platforms include Amazon Web Services (AWS) and Microsoft Azure.

Storage Area Network (SAN) Virtualization: This type of virtualization enables the pooling of storage resources from multiple physical devices, such as servers and storage arrays, into a single virtualized storage device. SAN virtualization allows for greater flexibility in storage management and can improve performance and availability. Examples of SAN virtualization software include IBM SAN Volume Controller and EMC VPLEX.

Memory Virtualization: This type of virtualization enables the pooling of physical memory resources across multiple physical servers, allowing virtual machines to access more memory than is available on a single physical server. Memory virtualization can improve performance and reduce the need for expensive memory upgrades. Examples of memory virtualization software include VMware vSphere and Red Hat Enterprise Virtualization.

Desktop as a Service (DaaS) Virtualization: This type of virtualization enables the delivery of virtual desktops to end users over the internet, without requiring them to have their own physical hardware. DaaS virtualization allows for greater flexibility and accessibility, as virtual desktops can be accessed from any device with an internet connection. Examples of DaaS virtualization providers include Amazon WorkSpaces and Citrix Virtual Apps and Desktops Service.

Network Functions Virtualization (NFV): This type of virtualization enables the virtualization of network functions, such as routing, switching, and firewalling, on commodity hardware. NFV allows for greater flexibility and agility in network management and can reduce costs by eliminating the need for expensive hardware appliances. Examples of NFV software include OpenStack and VMware NSX.

Hybrid Virtualization: This type of virtualization involves the use of multiple virtualization technologies to create a hybrid environment. For example, an organization might use full virtualization for their server infrastructure, but use containerization for their application deployment. Hybrid virtualization allows organizations to leverage the benefits of different virtualization technologies to meet their specific needs.

In-Memory Virtualization: This type of virtualization involves the use of in-memory databases, which store data entirely in memory rather than on disk. In-memory virtualization can improve performance and scalability for database applications, and can be used in conjunction with other virtualization technologies. Examples of in-memory database software include SAP HANA and Oracle TimesTen.

Internet of Things (IoT) Virtualization: This type of virtualization enables the virtualization of IoT devices, allowing multiple virtual instances of an IoT device to run on a single physical device. IoT virtualization allows for greater flexibility in IoT device deployment and can simplify device management. Examples of IoT virtualization software include Wind River Helix Virtualization Platform and Microsoft Azure Sphere.

Security Virtualization: This type of virtualization involves the use of virtualization technologies to improve security for IT infrastructure. For example, organizations might use virtualized firewalls or intrusion detection systems to protect their network. Security virtualization can improve the effectiveness of security measures and reduce costs by eliminating the need for expensive hardware appliances. Examples of security virtualization software include VMware NSX and Juniper vSRX.
