Microsoft Application Virtualization (also known as App-V;〔(【引用サイトリンク】 A Farewell to SoftGrid )〕 formerly Softricity SoftGrid)〔(【引用サイトリンク】 Microsoft Application Virtualization 4.5 is Now Available in Beta! )〕 is an application virtualization and application streaming solution from Microsoft. It was originally developed by Softricity, a company based in Boston, Massachusetts, acquired by Microsoft on July 17, 2006.〔(【引用サイトリンク】title=Microsoft Presspass - Microsoft Completes Acquisition of Softricity )〕 App-V represents Microsoft's entry to the application virtualization market, alongside their other virtualisation technologies such as Hyper-V, Microsoft User Environment Virtualization (UE-V), Remote Desktop Services, and System Center Virtual Machine Manager.〔(【引用サイトリンク】title=Microsoft Presspass - Microsoft Extends Virtualization Strategy, Outlines Product Road Map )〕 ==Overview== Microsoft Application Virtualization (MS App-V) platform allows applications to be deployed ("streamed") in real-time to any client from a virtual application server. It removes the need for traditional local installation of the applications, although a standalone deployment method is also supported. With a streaming-based implementation, the App-V client needs to be installed on the client machines and application data that is stored on the virtual application server is installed (streamed) to the client cache on demand when it is first used, or pre-installed in a local cache. The App-V stack sandboxes the execution environment so that an application does not make changes directly to the underlying operating system's file system and/or Registry, but rather contained in an application-specific "bubble". App-V applications are also sandboxed from each other, so that different versions of the same application can be run under App-V concurrently and so that mutually exclusive applications can co-exist on the same system. MS App-V thus allows centralized installation and management of deployed applications. It supports policy based access control; administrators can define and restrict access to the applications by certain users, or on certain computers, by defining policies governing the usage. App-V also features a tracking interface to track the usage of the virtualized application. Servers may be implemented in highly available configurations when desired. The App-V client presents the user with a neat, locally installed application experience for virtualized applications. Access to start the virtualized application appears to be identical to the locally install application, as extensions for the application are integrated into the user's desktop shell by the App-V client. When two or more virtual applications have a dependency on each other, the individual virtualized applications may also be configured to run together in a single isolated bubble. Microsoft App-V is an additional component requiring licensing for use. Licensing is user-based and is either acquired by licensing Microsoft Desktop Optimization Pack (MDOP) for use on client operating systems, or as part of the Microsoft Remote Desktop Server Client Access License for use on Remote Desktop Servers. MDOP is a suite of technologies available as a subscription for Software Assurance customers. There also exists a licensing model that exists for hosting (cloud services) providers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microsoft App-V」の詳細全文を読む スポンサード リンク
