Dell Desktop Virtualization Solutions DVS Enterprise Dell Desktop Virtualization Solutions DVS Enterprise The Challenge The Challenge Integrated Enterprises of all sizes are poised to explore alternatives to traditional end user computing. Solution Stack Many are reevaluating how their IT groups provision, manage, and support their workforce. IT administrators need ways to boost user mobility and work flexibility while also helping to tighten enterprise security, simplify management, and reduce the overall cost of owning and operating Delivery Models client systems. Dell™ Desktop Virtualization Solutions (DVS) are a cost-efficient way to enhance security, streamline management, and boost user productivity. Virtualization IT departments are facing an array of challenges, including: Roadmap Methodology Mobile Workers—Mobile workers need predictable and complete access to their work applications, tools, and data from outside the office. Benefits Explosion in Devices—IT is also dealing with an explosion in numbers and types of devices being used by employees. For instance, many organizations are feeling pressure from their Summary employees to enable connecting tablets to corporate networks and resources. Need to Simplify Desktop Management—Managing a complex desktop environment is costly, and pulls administrators away from strategic projects. IT desires to streamline desktop support operations, manage more users with more diverse needs, while reducing costs for key tasks, including provisioning desktops, deployment of updates, patches, and upgrades. Increasing Security Concerns—No enterprise wants their name in the news because of a security breach. Employee mobility, the explosion in devices, and consumerization all introduce risk and exposure for your company. Consumerization—Employees now expect organizations to allow the use of personal devices, like smartphones and home computers, to access work resources. Implementation Complexity—Desktop virtualization is inherently complex requiring orchestration of multiple inter-connected components spanning all traditional IT domains including; servers, storage, networks, enterprise software, management, hypervisors, connection brokers, and client devices. Designing and deploying a desktop virtualization solution can be a daunting task, especially when considering resources, budgets, and ROI. ® Dell Inc., 2012 Dell Cloud Client Computing 1 Dell Desktop Virtualization Solutions DVS Enterprise The Challenge Dell Integrated Solution Stack Integrated Accelerate your time to value Solution Stack DVS Enterprise enables desktop virtualization from pilots to full JuniperServers (Dell J- Series) scale deployments as a complete datacenter solution inclusive of all hardware, software and services to deliver operating environment, DellEX4500 PowerEdge 10GbE Delivery Models applications and data to most Internet-connected computing devices in a cost-effective and predictable way– improving employee ToR Network Switches Virtualization productivity, while reducing IT management complexity.

Both server virtualization and desktop virtualization are briefly presented, but desktop virtualization is discussed in more details. As the size of computer systems grows every day with new applications, and with new client and market requirements, it is obvious that something must be done to ease the administration and effectively secure data. Additionally, disaster recovery plans must be improved too. Virtualization has solved many of these requirements and has become more and more popular so that many companies decided to implement a virtual server, virtual storage or/and virtual desktops. The paper lists the reasons why to implement virtual desktops and servers and what are the main benefits of such implementations. Virtual environments the also have some downsides, which are presented, explained and compared to the advantages.

  • Development of Web-Based Remote Desktop to Provide Adaptive User Interfaces in Cloud Platform Shuen-Tai Wang, Hsi-Ya Chang
    World Academy of Science, Engineering and Technology International Journal of Computer and Information Engineering Vol:8, No:8, 2014 Development of Web-Based Remote Desktop to Provide Adaptive User Interfaces in Cloud Platform Shuen-Tai Wang, Hsi-Ya Chang purpose of cloud platforms and services, and it is a promising Abstract —Cloud virtualization technologies are becoming more approach to consolidating multiple services onto a smaller and more prevalent, cloud users usually encounter the problem of how number of computing resources. A virtualized server to access to the virtualized remote desktops easily over the web environment allows computing resources to be shared among without requiring the installation of special clients. To resolve this multiple performance-isolated platforms called virtual issue, we took advantage of the HTML5 technology and developed web-based remote desktop. It permits users to access the terminal machines [4], [5]. A virtual machine is a software which running in our cloud platform from anywhere. We implemented implementation of a machine that executes related programs a sketch of web interface following the cloud computing concept that like a physical machine. Each virtual machine includes its own seeks to enable collaboration and communication among users for system kernel, OS, supporting libraries and applications. A high performance computing. Given the development of remote hypervisor provides a uniform abstraction of the underlying desktop virtualization, it allows to shift the user’s desktop from the physical machine, and multiple virtual machines can execute traditional PC environment to the cloud platform, which is stored on a remote virtual machine rather than locally. This proposed effort has simultaneously on a single hypervisor.
