New Virtualization Technology (Vdi)

Google+ Pinterest LinkedIn Tumblr +

Desktop computing has become a core technology for enterprise IT infrastructures providing enormous flexibility and mobility. But with that flexibility come challenges in costs associated with operations, licenses, support and maintenance.

The mass adoption of server virtualization is one of the biggest data center transformations to hit the IT world in years helping organizations consolidate resources and improve resource utilization. While cost savings are being realized with server virtualization, it is the desktop environment where organizations are now in search of economic-sensible, cost savings solutions.

Virtual Desktop Infrastructure (VDI) brings virtualization to the desktop environment delivering enterprise-class control and manageability while maintaining the familiar end-user environment. VDI virtualizes a desktop image that is deployed from a centralized server providing the reduction of operational costs and improved security while maintaining the current end-user experience – no learning curve. VDI technology provides companies with a true win-win.

Achieving these benefits requires evaluation of some core solution criteria.

  • Cost efficiencies: All VDI solutions promise cost efficiencies but you need to validate these promises to ensure the solution you select provides the largest savings possible. Savings needs to come from a variety of areas: consolidation of desktops to servers, power, cooling, space, licensing, and management costs. Virtual machines provide the lowest consolidation ratios translating into lower savings through the ecosystem.

  • Green Computing: Not all VDI solutions are equally green and it comes down to the solution design. Criteria include system resource allocation, ability to use existing hardware & software drivers and utilizing technology in your servers to reuse your older hardware. Virtual machine solutions require pre-allocation of resources that remain in effect through the entire lifecycle, if over allocated, resources are wasted. Hardware and software drivers are translated through virtual machine micro-kernels creating overhead.

  • Improved Manageability: Resources are lean today so they need to be as efficient as possible. Virtual machine solutions create road blocks to software updates across all servers by requiring each administrator to login and perform the update. Virtual machines require systems to be off line to perform backups.

  • Data Security and Integrity: Compromised business data can be an embarrassment to an organization. Virtual machine solutions place home grown micro-kernel layers on top of the operating system. These micro-kernel layers have not been matured like the OS, leaving your environment vulnerable. Read the results from an example: http://blogs.vmware.com/console/2008/08/letter-from-vmw.html

• Full user experience with no compromises: Most VDI solutions make this claim but at what cost? The disk space required per desktop needs to be as small as possible. Virtual machines require up to 250 Mbytes of RAM memory plus another 50 Mbytes to accommodate the hypervisor.computing has become a core technology for enterprise IT infrastructures providing enormous flexibility and mobility.
