VMware Definition
VMware is a virtualization and cloud computing software provider based in Palo Alto, California. Founded in 1998, VMware is a subsidiary of Dell Technologies. EMC Corporation originally acquired VMware in 2004; EMC was later acquired by Dell Technologies in 2016. VMware bases its virtualization technologies on its bare-metal hypervisor ESX/ESXi in x86 architecture.
With VMware server virtualization, a hypervisor is installed on the physical server to allow for multiple virt...

Storage Distributed Resource Scheduler (DRS)
Storage Distributed Resource Scheduler (DRS)
VMware DRS (Distributed Resource Scheduler) is a load balancing utility that assigns and moves computing workloads to available hardware resources in a virtualized environment.
DRS can be configured to recommend workload balancing or to automatically move workloads. VMware DRS users can refine resource allocation with affinity rules and anti-affinity rules. The utility allows VMware administrators to prioritize resources according ...

Thick Provisioning Definition
Thick Provisioning Definition
In virtual storage, thick provisioning is a type of storage allocation in which the amount of storage capacity on a disk is pre-allocated on physical storage at the time the disk is created.
This means that creating a 100GB virtual disk actually consumes 100GB of physical disk space, which also means that the physical storage is unavailable for anything else, even if no data has been written to the disk.
Thick provisioning contrasts with thin provisio...

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...
