Trango Virtual Processors was founded in 2004 by Pierre Coulombeau and Fabrice Devaux as a subsidiary of ELSYS Design group. Trango's purpose was to develop a real-time mobile hypervisor. It was acquired by VMware in October 2008. [1]
Trango developed a mobile hypervisor that supported ARM architectures (ARMv5 and ARMv6) and MIPS architectures, and could run Symbian OS, WinCE, and Linux mobile operating systems, and a supporting integrated development environment (IDE).
VMware rebranded Trango's product as the VMware Mobile Virtualization Platform, which was later renamed VMware Horizon Mobile. [2] [3]
Computer operating systems (OSes) provide a set of functions needed and used by most application programs on a computer, and the links needed to control and synchronize computer hardware. On the first computers, with no operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral devices like printers and punched paper card readers. The growing complexity of hardware and application programs eventually made operating systems a necessity for everyday use.
VMware LLC is an American cloud computing and virtualization technology company headquartered in Palo Alto, California. VMware was the first commercially successful company to virtualize the x86 architecture.
Xen is a free and open-source type-1 hypervisor, providing services that allow multiple computer operating systems to execute on the same computer hardware concurrently. It was originally developed by the University of Cambridge Computer Laboratory and is now being developed by the Linux Foundation with support from Intel, Citrix, Arm Ltd, Huawei, AWS, Alibaba Cloud, AMD, Bitdefender and EPAM Systems.
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.
Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform. The table below compares basic information about platform virtualization hypervisors.
In computing, virtualization is the use of a computer to simulate another computer. The following is a chronological list of virtualization technologies.
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
VMware ESXi is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.
Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization emulates the hardware environment of its host architecture, allowing multiple OSes to run unmodified and in isolation. At its origins, the software that controlled virtualization was called a "control program", but the terms "hypervisor" or "virtual machine monitor" became preferred over time.
Open Virtualization Format (OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines.
Pano Logic was a manufacturer of devices which present virtual desktops to the end user with no local processing power. They describe this concept as "zero client". This is perceived as offering benefits in end-user support and in power provision to desks. OEM versions have been included in displays from some vendors, allowing a single unit to be deployed. The company failed in October 2012. In March 2013, Propalms announced they had acquired the rights to support Panologic customers, and will "help transition the customer base to a new platform".
VirtualLogix, Inc. provides real-time virtualization software and related development tools for embedded systems. The company was founded in 2002. In September 2010, VirtualLogix was acquired by Red Bend Software.
In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers.
VMware Horizon is a commercial desktop and app virtualization product developed by VMware, Inc for Microsoft Windows, Linux and macOS operating systems. It was first sold under the name VMware VDM, but with the release of version 3.0.0 in 2008 it was changed to "VMware View". The name was updated to "Horizon View" with the launch of version 6 in April 2014 and is now referred to as "VMware Horizon" to represent desktop and app virtualization.
Open Kernel Labs is a privately owned company that develops microkernel-based hypervisors and operating systems for embedded systems. The company was founded in 2006 by Steve Subar and Gernot Heiser as a spinout from NICTA. It was headquartered in Chicago, while research and development was located in Sydney, Australia. The company was acquired by General Dynamics in September 2012.
Second Level Address Translation (SLAT), also known as nested paging, is a hardware-assisted virtualization technology which makes it possible to avoid the overhead associated with software-managed shadow page tables.
Virsto develops a VM-centric storage hypervisor. The company is privately funded and headquartered in Sunnyvale, California. On February 11, 2013, VMware announced that it had signed a definitive agreement to acquire Virsto.
Software-defined storage (SDS) is a marketing term for computer data storage software for policy-based provisioning and management of data storage independent of the underlying hardware. Software-defined storage typically includes a form of storage virtualization to separate the storage hardware from the software that manages it. The software enabling a software-defined storage environment may also provide policy management for features such as data deduplication, replication, thin provisioning, snapshots and backup.
Jason Nieh is a professor of Computer Science and co-director of the Software Systems Laboratory at Columbia University. He was the technical advisor to nine States regarding the Microsoft antitrust settlement and has been an expert witness before the United States International Trade Commission. He was Chief Scientist of Desktone, which was purchased by VMware, and currently holds the same position at CertiK.
