You will find just two kinds of program virtualization: streaming and distant.
End users see and connect to their programs over a network by means of a remote screen protocol. The distant programs may be fully incorporated using the user's background so they act and appear the same as programs that are local, through technology called seamless windows. A continuous network connection has to be kept to function in order to get a distant program.
On the end user's local computer, the virtualized program is executed with streaming programs. Just specific portions of an application have to to be able to establish; the rest may be downloaded in the background. A streamed program can function with no network connection once fully downloaded. Various models and measures ensure that they are sometimes removed when closed, and that streaming programs is not going to restrict other programs.
Both types of program virtualization have advantages from central direction. Programs may be set up, patched, and updated once instead of for a complete environment,. Licensing may also be less difficult to manage when the programs are being provisioned by IT instead enabling users.
In computer science, network function virtualization (NFV) is a network architecture theory that uses the technologies virtualization to virtualize entire groups of network node functions into building blocks which could connect, or chain together, to create communication services.
NFV relies upon, but differs from, traditional server-virtualization techniques, such as those IT. A virtualized network function, or VNF, may consist of one or more virtual machines running different software and processes, on the top of regular high-volume servers, switches and storage, or even cloud computing infrastructure, instead of having custom hardware appliances for every network function.
As an example, a virtual session border control could be installed to shield a network without the typical price and intricacy of installing and obtaining physical units. Other examples include virtualized load balancers, firewalls, intrusion detection devices and WAN accelerators.
