In all cases these are “virtual” solutions from a user perspective, meaning they exist in physical form in the network on servers but are allocated to, and shared among, a number of users on an assigned at access basis. These are various strategies for delivering user computing and application resources as online services rather than locally implemented instances. This article will focus on a specific area of virtualization affecting both individual and corporate users of computing systems and applications, referred to variously as hosted virtual desktops (HVD), web desktops, web OS and online or “cloud” computers. The proliferation of virtualization technologies, products and services has lead to an overwhelming array of options to both developers and IT administrators. Anyone familiar with the internal workings of computing devices and networks is already familiar with the most commonly used forms of virtualization – including virtual memory in PCs and servers, and virtual private networks used to deploy secure access to private network and computing resources over public infrastructure. There are lots of different forms and formats of virtualization affecting platforms, computers, infrastructure, applications and services. Generally speaking virtualization refers to the abstraction of computing resources (see Wikipedia for more on this topic). One of the hottest topics in computing and communications is virtualization, but what exactly does it mean and how does it impact users of computing and communications resources? at .InternalCreateIntermediateFormat(Stream definitionStream, String& description, String& language, ParameterInfoCollection& parameters, DataSourceInfoCollection& dataSources, DataSetInfoCollection& sharedDataSetReferences, UserLocationFlags& userReferenceLocation, ArrayList& dataSetsName, Boolean& hasExternalImages, Boolean& hasHyperlinks, Byte& dataSetsHash)Īt .CreateIntermediateFormat(Byte definition, String& description, String& language, ParameterInfoCollection& parameters, DataSourceInfoCollection& dataSources, DataSetInfoCollection& sharedDataSetReferences, UserLocationFlags& userReferenceLocation, ArrayList& dataSetsName, Boolean& hasExternalImages, Boolean& hasHyperlinks, Byte& dataSetsHash)Īt .CompileOdpReport(PublishingContext reportPublishingContext, PublishingErrorContext errorContext, String& reportDescription, String& reportLanguage, ParameterInfoCollection& parameters, DataSourceInfoCollection& dataSources, DataSetInfoCollection& sharedDataSetReferences, UserLocationFlags& userReferenceLocation, ArrayList& dataSetsName, Boolean& hasExternalImages, Boolean& hasHyperlinks, Byte& dataSetsHash)Īt .CreateIntermediateFormat(PublishingContext reportPublishingContext)Īt summary of today's virtualization technologies and the distinguishing aspects of the different types of virtualization and cloud computing, followed by an examination of an interesting new online virtual personal computer service for smart phone - including iPhone - users called AlwaysOnPC.
