VMware LLC is an American cloud computing and virtualization technology company headquartered in Palo Alto, California. [2] VMware was the first commercially successful company to virtualize the x86 architecture. [3] VMware's desktop software runs on Microsoft Windows, Linux, and macOS.
Wireless network virtualization can have a very broad scope ranging from spectrum sharing, infrastructure virtualization, to air interface virtualization. Similar to wired network virtualization, in which physical infrastructure owned by one or more providers can be shared among multiple service providers, wireless network virtualization needs ...
VMware ESXi (formerly ESX) 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.
VMware Infrastructure is a collection of virtualization products from VMware. Virtualization is an abstraction layer that decouples hardware from operating systems. The VMware Infrastructure suite allows enterprises to optimize and manage their IT infrastructure through virtualization as an integrated offering.
As a result, companies such as VMware created a resource called a virtual switch. The purpose of the virtual switch was to provide network connectivity within the virtual environment so that virtual machines and applications could communicate within the virtual network as well as with the physical network.
The company initially manufactured converged datacenter units known as Vblock, which incorporate Cisco servers and networking hardware, EMC storage systems, and VMware for virtualization. [35] Later, VxBlock was added providing the ability for customers to run VMware NSX. In 2015, VxRack and in 2016 VxRail were added as separate products.
The virtualization introduces only a negligible overhead and allows running hundreds of virtual private servers on a single physical server. In contrast, approaches such as full virtualization (like VMware) and paravirtualization (like Xen or UML) cannot achieve such level of density, due to overhead of running multiple kernels. From the other ...
In October 2012, a group of telecom operators published a white paper [4] at a conference in Darmstadt, Germany, on software-defined networking (SDN) and OpenFlow.The Call for Action concluding the White Paper led to the creation of the Network Functions Virtualization (NFV) Industry Specification Group (ISG) [5] within the European Telecommunications Standards Institute (ETSI).
