Server Virtualization Definition

server virtualization Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. The virtual environments are sometimes called virtual private servers, but they are also known as guests, instances, containers or emulations. There are three...

Hypervisor Definition

Hypervisor Definition A hypervisor is a function which abstracts -- isolates -- operating systems and applications from the underlying computer hardware. This abstraction allows the underlying host machine hardware to independently operate one or more virtual machines as guests, allowing multiple guest VMs to effectively share the system's physical compute resources, such as processor cycles, memory space, network bandwidth and so on. A hypervisor is sometimes also called a virtual machine ...

8 Benefits of implementing Hyper-V Network Virtualization

8 Benefits of implementing Hyper-V Network Virtualization Hyper-V Network Virtualization technology, sometimes referred as HNV, is primarily designed to be used by the hosting providers, but every SMB should know the benefits offered by HNV. Microsoft Hyper-V Network Virtualization is introduced with a new module called “WNV”. WNV stands for “Windows Network Virtualization”. The WNV module was first introduced with Windows Server 2012 as an additional component that you need to enable th...

Host-based virtual machine

Host-based virtual machine A host-based virtual machine is an instance of a desktop operating system that runs on a centralized server. Access and control is provided to the user by a client device connected over a network. Multiple host-based virtual machines can run on a single server. With a host-based virtual machine, data is contained on the server, server resources can be allocated to users as needed, users can work from a variety of clients in different locations, and all of the v...

Application Virtualization

Application Virtualization App virtualization (application virtualization) is the separation of an installation of an application from the client computer that is accessing it. There are two types of application virtualization: remote and streaming. Remote applications run on a server. End users view and interact with their applications over a network via a remote display protocol. The remote applications can be completely integrated with the user’s desktop so that they appear and behave...

Desktop Virtualization

Desktop Virtualization Desktop virtualization is the concept of isolating a logical operating system (OS) instance from the client that is used to access it. There are several different conceptual models of desktop virtualization, which can broadly be divided into two categories based on whether or not the operating system instance is executed locally or remotely. It is important to note that not all forms of desktop virtualization involve the use of virtual machines (VMs). Host-based...

Data Virtualization

Data Virtualization Data virtualization is an umbrella term used to describe any approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted or where it is physically located. You are probably familiar with the concept of data virtualization if you store photos on the social networking site Facebook.  When you upload a photo to Facebook from your desktop computer, you must provide t...

Storage Virtualization Definition

Storage Virtualization Definition Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization helps the storage administrator perform the tasks of backup, archiving, and recovery more easily -- and in less time -- by disguising the actual complexity of a storage area network (SAN).  Administrators can implement virtualization with software app...

Network Virtualization

Network Virtualization Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. Each channel is independently secured. Every subscriber has shared access to all the resources on the network from a single computer. Network management can be a tedious and time-consuming...
