  • Another connection broker provider is Ericom Software, with PowerTerm WebConnect DeskView. WebConnect supports over a dozen hypervisors. This flexibility helps organizations save money by allowing them to select the lowest cost hypervisor that meets their needs.

    WebConnect DeskView also includes Ericom Blaze, a software product that accelerates and compresses standard Microsoft RDP, so it speeds RDP while conserving bandwidth. Blaze accelerates RDP performance by as much as 25 times.

  9. 9. Virtual Desktop Infrastructure - Application Streaming & Virtualization<br />APPLICATION STREAMING & VIRTUALIZATION <br />Install application on server; execute on local machine. <br />Advantages: installation, upgrade, roll-back, delivery speed, ease of application support (management).<br />Application Virtualization Providers:<br />Altiris/Symantec Workspace Virtualization <br />Citrix Application Streaming<br />Microsoft App-V<br />VMware ThinApp<br />4<br />
  10. 10. Virtual Desktop Infrastructure -OS Provisioning<br />OS PROVISIONING<br />Single image on multiple workstations<br />Advantages: upgrade or roll-back an OS quickly. When virtual desktops use OS provisioning, (valuable) storage is saved<br />OS Provisioning Providers:<br />Citrix Provisioning Server, part of the XenDesktop and XenApp family, DoubleTake Flex, Wanova Mirage and the VMware View Composer<br />5<br />
  11. 11. Virtual Desktop Infrastructure - Server-Hosted Virtual Desktop (VDI)<br />SERVER-HOSTED VIRTUAL DESKTOP (VDI) <br />Two kinds of VDI: <br />server-hosted desktop<br />With server-hosted, desktops no longer bound to a location. Client display is delivered via Microsoft RDP, Citrix ICA/HDX, Teradici/VMware ―PC-over-IP<br />client-hosted desktop<br />Server-Hosted VDI Providers:<br />Microsoft, Citrix, Kaviza, Quest, Oracle/SUN and VMware<br />6<br />

  13. 13. REMOTE DESKTOP SERVICES (RDS)<br /> (Also known as Shared Remote Desktop)<br />Every user has unique terminal server session that runs in the data center<br />Programs execute centrally on terminal server versus locally on desktop<br />desktop or application is location independent<br />Low TCO<br />Remote Desktop Services (RDP) Providers:<br />Microsoft<br />Citrix<br />Quest<br />Virtual Desktop Infrastructure – RDS (Terminal Server)<br />8<br />
  14. 14. CLIENT-SIDE DESKTOP VIRTUALIZATION (VDI).<br /> (Also known as Client Hosted Virtual Desktop)<br />virtual machines run locally on the client device<br />Advantages:<br />hypervisor ensures that each virtual machine is hardware-independent<br />simultaneously use a number of virtual machines at the same workstation<br />Two types of hypervisors:<br />bare-metal client - Citrix XenClient bare-metal hypervisor<br />client-hosted hypervisor - Microsoft Virtual PC and MED-V, VMware ACE and Fusion, VMware View Client with Local Mode and Sun VirtualBox<br />Virtual Desktop Infrastructure – Client-Side Desktop Virtualization (VDI)<br />9<br />

  17. 17. Benefits of Application Virtualization – Citrix XenApp*<br />Eliminate application conflicts and OS instability resulting from desktop application installation<br />Reduce the costs associated with regression testing, deployment, maintenance, updates, and de-provisioning for applications running locally on users‘ machines<br />Offer applications as an on-demand service<br />Lower support costs by automatically updating and repairing applications every time they are used<br />Speed regulatory compliance by eliminating the need for extensive testing to certify applications<br />Enhance security by giving IT administrators complete control over applications delivered to desktops, even those of unmanaged partners and users<br />* Citrix XenApp is included in Citrix XenDesktop Platinum<br />
  18. 18. Benefits of Application Virtualization: Microsoft App-V<br />Transforms apps into centrally-managed virtual services that are never conflict with other apps.<br />Streams applications on-demand to any device.<br />All applications are instantly available on any licensed device depending on user rights<br />Standalone mode provides app caching on the local client for offline usage<br />App usage & license metering are managed centrally<br />Patch or upgrade once to the server<br />Fully integrates with SCCM<br />

Cisco’s Unified Computing System (UCS)Benefits<br />Higher Availability<br />Less Infrastructure<br />Unified LAN/SAN Fabric based on FCoE 10GigE<br />Less Management<br />Faster Application Deployment<br />Lower Operating Expenses<br />Repurpose Physical & Virtual Servers without Service Disruption<br />Single Integrated System<br />
