The Virtual Desktop Revolution


Published on

Virtual desktop infrastructure (VDI) represents the future of enterprise desktop computing and brings with it the detachment of OSs and applications from physical endpoints—a compelling trend that promises greater flexibility, scalability, cost savings and security benefits. The movement also represents radical, and possibly painful, changes in market dynamics for providers of endpoint hardware, software and services.

Yankee Group analysts Phil Hochmuth and Zeus Kerravala dissect the future of VDI and discuss what the technology has to offer enterprises today.

    15. 15. Desktop virtualization: percent of desktops virtualized Base: Asked to those who have deployed or are planning to deploy desktop virtualization within 24 months <ul><li>VDI deployments are wide, but shallow </li></ul><ul><ul><li>While more than two-thirds of the enterprises that say they have VDI, none of the organizations have more than a third of their total desktops virtualized </li></ul></ul><ul><ul><li>Most deployments are very limited </li></ul></ul><ul><ul><ul><li>Departmental roll-outs </li></ul></ul></ul><ul><ul><ul><li>Specific end-user scenarios (task worker, call center, etc.) </li></ul></ul></ul><ul><ul><li>Overall, VDI is not yet viewed as a viable replacement to standard endpoint PCs </li></ul></ul>
    16. 16. Desktop virtualization: motivations for deployment Base: Asked to those who have deployed or are planning to deploy desktop virtualization <ul><li>Aspirational and innovative drivers for VDI are not resonating with enterprises </li></ul><ul><ul><li>Management cost and complexity reductions are what appeal to enterprises </li></ul></ul><ul><li>Enterprise consumerization does not drive VDI </li></ul><ul><ul><li>Bring-your-own-PC is a popular idea associated with VDI, but it’s not what’s driving deployments in enterprises </li></ul></ul>(n=218)

    26. 26. What an Anywhere Desktop Architecture will look like <ul><li>This can be narrowed down to several attributes, some of which are in various stages of availability today, while others are not: </li></ul><ul><ul><li>A centrally controlled and hosted master operating system image capable of being patched, maintained and updated once, but replicated widely across the enterprise </li></ul></ul><ul><ul><li>Protocols for efficiently delivering not only video and I/O to end-users, but also rich media (streaming audio/video) and support for peripherals (i.e., USB devices) </li></ul></ul><ul><ul><li>Separation of hosted end-user identity, data and personalized settings from the virtualized “master image,” enabling employees to continue the same data-access and operating environment experience regardless of what changes are made to the virtualized master image </li></ul></ul><ul><ul><li>The ability to maintain a persistent endpoint computing experience, regardless of what network end-users are attached to </li></ul></ul><ul><ul><li>Identity, access control and data security policies that follow employees as they access virtual desktops from any location and any device </li></ul></ul><ul><ul><li>The ability to extend delivery of applications and operating environments to devices beyond PCs and laptops (i.e., PDAs, smartphones, netbooks) </li></ul></ul>

    28. 28. Conclusions: VDI will drive greater IT efficiency and end-user productivity <ul><li>IT can move away from purchasing/maintaining client devices </li></ul><ul><ul><li>Workers buy their own laptop/client device </li></ul></ul><ul><ul><li>IT leverages application virtualization and desktop virtualization to deploy the work environment </li></ul></ul><ul><ul><li>Work environment is encapsulated in a VM and accessed over a secure network </li></ul></ul><ul><ul><li>Benefits: </li></ul></ul><ul><ul><ul><li>IT can centrally manage and secure </li></ul></ul></ul><ul><ul><ul><li>Malware can’t propagate </li></ul></ul></ul><ul><ul><ul><li>Fewer IT resources required to manage </li></ul></ul></ul><ul><ul><ul><li>Users have freedom to buy any client </li></ul></ul></ul><ul><ul><li>Challenges: </li></ul></ul><ul><ul><ul><li>VDI protocols can run poorly over the WAN </li></ul></ul></ul><ul><ul><ul><li>Highly bandwidth-intensive </li></ul></ul></ul><ul><ul><ul><li>Multimedia optimization required </li></ul></ul></ul><ul><ul><ul><li>Creates a lack of visibility into the network </li></ul></ul></ul><ul><ul><ul><li>Quality of service is hard to maintain </li></ul></ul></ul>
    29. 29. Recommendations for enterprise IT leadership <ul><li>Break from traditional thinking about where VDI fits into an enterprise. </li></ul><ul><ul><li>VDI should not be thought of as a solution to a specific IT problem. It is a potentially transformative technology that can make every employee in an enterprise more productive, versatile, secure and manageable. </li></ul></ul><ul><li>Prepare for another major IT management/workforce integration. </li></ul><ul><ul><li>The advent of UC forced telecom departments to roll up IP network service groups. Similarly, network operations and applications developers have converged to support service-oriented architecture (SOA) and network-optimized Web apps. Expect this to happen between desktop support staff and the network group. </li></ul></ul><ul><li>Include desktop virtualization as part of an enterprise-cloud architecture. </li></ul><ul><ul><li>Virtualization, SaaS and cloud computing are reshaping IT, but the point is missed if all this infrastructure is built just to support the same old PC architecture that has been in place for the last two decades. As enterprises move applications to “internal clouds,” endpoint operating system and locally stored (and company-owned) end-user data should move skyward as well. </li></ul></ul><ul><li>Identify your desktop security challenges and look for ways VDI might help. </li></ul><ul><ul><li>Look for specific problems and issues VDI can solve. VDI can ease the problem of inconsistent (and possibly vulnerable) versions of client applications and OSs across the enterprise. The platform is potentially also a good solution for giving secure remote access to external groups, such as contractors, outsourcers or partners. </li></ul></ul>
    30. 30. Q&A <ul><li>Did you know? Despite the economic downfall, 50 percent of large enterprises have not shifted their plans for VDI implementation over the next 12 to 24 months. </li></ul>Yankee Group’s Attitude & Behavior Surveys track this data and more.
