Cloud is still not well understood. Indeed the very name suggests fogginess. This is why we see such a profusion of "what is cloud" presentations, all, or most, providing a very vendor-centric view. In the presentation below, I've attempted instead to provide a general overview of how cloud is perceived by different players, and (surprise, surprise) to position Citrix technologies with respect to the most general views of 'cloud'.Cloud computing (for the IT professional at least) includes notions of Software as a Service, Infrastructure as a Service, and Platform as a Service. These categories are well understood and largely accepted, but are imperfect. Very clearly, all can be applied to offerings from external providers as well as to operating models, or "patterns" within the enterprise. Furthermore, we're seeing a great deal of category leak at present, with SaaS offerings on IaaS, PaaS offerings that can be hosted as IaaS and offered as SaaS, etc, etc.Citrix has various technologies that enable Infrastructure as a Service and this has been the focus of our C3 (Citrix Cloud Center) marketing to date. However Citrix has long been a leader in bringing the notions of Software as a Service to the enterprise. This is something we've been doing for over a decade with our WinFrame, MetaFrame and XenApp technology. It's the core notion of today's Citrix Delivery Center, now extended to desktop virtualization.Here's an updated cloud computing deck, originally used at some of the Citrix iForum events (and posted here), that I recently presented as a keynote at the IT Architect Regional Conference in Malaysia ( Please let me know what you think.

IaaS is </p> <p>more complex than it may </p> <p>appear. IaaS cloud vendors </p> <p>mean many different things by </p> <p>cloud.</p> <p>Some emphasize base level </p> <p>virtualization virtual servers, virtual storage, and virtual </p> <p>networks.</p> <p>Others emphasize resource </p> <p>management, multi-tenancy (in </p> <p>all its forms), usage monitoring, </p> <p>and optimizing across the farm.</p> <p>Still others are mainly about </p> <p>application management, </p> <p>which components work where, </p> <p>and how they need to interact.</p> <p>And some are mainly about </p> <p>providing access and </p> <p>automation in the cloud.</p> <p>Operational efficiencyOff-premise</p> <p>On-Premise</p> <p>The key promise of IaaS is to bring </p> <p>improved operational efficiency from </p> <p>virtual server agility. </p> <p>While much of the rhetoric focuses on off-</p> <p>premise cloud, on-premise (or private) </p> <p>cloud offers immediate benefits to </p> <p>enterprise IT.</p> <p>What else?</p> <p>SaaSSoftware as a Service</p> <p>Software as a Service or SaaS</p> <p>also brings important cloud ideas for the enterprise.</p> <p>Citrix is the fifth largest </p> <p>external SaaS vendor </p> <p>globally with the Citrix </p> <p>Software as a Service </p> <p>offerings. </p> <p>SSL 001000111010101 SSL 001000111010101 SSL 001000111010101 SSL 001000111010101 SSL 001000111010101</p> <p>Application Delivery=</p> <p>Enterprise SaaS</p> <p>Abstract connectionHigh-fidelity experienceCommon security model</p> <p>etcetc </p> <p>There are enormous benefits </p> <p>from treating all enterprise </p> <p>applications as SaaS as applications to be delivered to </p> <p>end users on demand.</p> <p>Users Apps</p> <p>Where Does Citrix Fit?
