Abstract:

Cloud computing is revolutionizing IT server operations and organizations are beginning to embrace the cloud computing paradigm for desktop computing. Cloud computing refers to users receiving IT services over the LAN, WAN, or internet from a datacenter with dynamically scalable virtualized resources. Two approaches to serving desktops from the cloud are Virtual Desktop Infrastructure (VDI) and Terminal Services-based remote desktops. These desktop replacement solutions move desktop processing and storage to the datacenter and require a client at the user’s desk which transmits keyboard and mouse inputs to the datacenter and receives display information. This paper compares the quantitative and qualitative benefits of two centralized desktop computing architectures; a VDI solution and a Terminal Services-based Trusted Computing Solution (TCS) and the relevant cost drivers associated with each approach to a typical distributed desktop computing model.
A centralized desktop computing model requires a significant upfront investment in design, testing, and implementation, in addition to hardware and software. This paper uses representative costs that approximate the cost of thin client devices, datacenter servers, software, and enterprise storage. These upfront investment costs are offset by cost savings from longer technology refresh cycles and reduced operations and management (O&M) costs in comparison to a baseline desktop computing model. This paper estimates life cycle costs for each alternative, calculates the return on investment (ROI) of each alternative relative to the baseline, conducts sensitivity analysis, and examines the cost drivers associated with each alternative.
In addition to the quantitative analysis, this paper explores the qualitative benefits of centralized computing. Centralized desktop computing increases data security and mobility, decreases downtime, and reduces bandwidth and electrical consumption. On the other hand, centralized desktop computing has reduced 3D graphics and multimedia support and allows for fewer compatible peripheral devices. In addition, this paper compares the qualitative benefits of VDI vs. TCS and identifies emerging technology desktop trends such as enterprise migration and hardware improvement.
VDI and TCS are logical extensions of the current IT trend towards cloud computing, consolidated datacenters with server and storage virtualization. The paper utilizes similar methodologies to the submitted paper entitled “The Economics of Cloud Computing – Addressing the Benefits of Infrastructure in the Cloud”; therefore it serves as a desktop computing-based complement to that infrastructure-based paper. We anticipate an organization’s decision to adopt a VDI or TCS solution will result in a significant reduction in O&M cost and an increase in ROI as compared to the traditional distributed desktop model. Because of this, we expect organizations to continue to embrace this emerging technology, moving desktops to the cloud.
