What is Virtualization

Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer—processors, memory, storage and more—to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware.

Virtualization reduce capital and operating costs, minimized or eliminated downtime, Greater business continuity and disaster recovery.

Virtualization allow you to divide a single server and convert it in various virtuals independent logical servers running the same roles and services as they were physical.

Virtualization can increase IT agility Flexibility and scalability while creating significant cost savings. Greater workload mobility, increased performance and availability of resources.

Virtual Services include

Virtual desktop infrastructure VDI: defined as the hosting of desktop environments on a central server. Desktop images run within virtual machines (VMs) and are delivered to end clients over a network.

Hardware Virtualization: or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources.

Servers Virtualization: It is a method of partitioning one physical server into numerous virtual servers, each of which run its own operating system, applications and functions as an independent server.

Storage Virtualization: is "the process of presenting a logical view of the physical storage resources to" a host computer system, "treating all storage media in the enterprise as a single pool of storage.

Security

Virtualization offers some security benefits. For example, VMs infected with malware can be rolled back to a point in time (called a snapshot) when the VM was uninfected and stable; they can also be more easily deleted and recreated. You can’t always disinfect a non-virtualized OS, because malware is often deeply integrated into the core components of the OS, persisting beyond system rollbacks.

Virtualization also presents some security challenges. If an attacker compromises a hypervisor, they potentially own all the VMs and guest operating systems. Because hypervisors can also allow VMs to communicate between themselves without touching the physical network, it can be difficult to see their traffic, and therefore to detect suspicious activity. A Type 2 hypervisor on a host OS is also susceptible to host OS compromise. The market offers a range of virtualization security products that can scan and patch VMs for malware, encrypt entire VM virtual disks, and control and audit VM access.
