  1. Cloud Computing General Operation and Facts As of 6/19/2012

  2. Cloud Computing • What is Cloud Computing? • Why VDI? • Installing the Virtual Desktop • Accessing the Virtual Desktop

  3. What is Cloud Computing? Differences, advantages, and types

  4. What is Cloud Computing? Laptops Cloud Computing Cluster of Servers Desktops Thin Clients

  5. What is Cloud Computing? • The Virginia Western definition of cloud computing is a connection to a Microsoft Windows based server, which allows you to run Microsoft Office plus other applications from the server just as if you were directly connected to the VWCC network. • The server is hosted, run, delivered and supported by a central location (IET). • The server can be accessed by desktops, laptops, thin clients and home computers; basically any computer connected to the Internet. • Gartner predicts that 40% of the world-wide professional PC market will be hosted desktops by 2013.

  6. What is a Thin Client? • Thin Client – a computer or computer program which depends heavily on a server to fulfill its traditional computational roles. • Fat Client (aka Thick Client or Heavy Client) - a computer that is designed to take on these roles itself. Note: it’s only considered a client if connected to a host server. • The most common type of modern thin client is a low-end computer terminal which concentrates solely on providing a graphical user interface to the computer with no hard drive or other features other than maybe USB ports.

  7. Additional Terms to Learn • Pool – a place where virtual groups exist • Sandbox – a file folder where program specific information from packaged applications is stored • Refresh – on virtual desktops, this is the term for reimaging your virtual desktop • Virtual Desktop Infrastructure or Interface (VDI) – a server computing module enabling desktop virtualization • VMware View Client – the program VWCC uses to access cloud computing

  8. Why VDI? Advantages to using the Virtual Desktop Interface

  9. Why VDI? • Access Anywhere – Access VW LAN from anywhere with Internet Support • Mobile Device Support – Access with Ipad, tablet or smartphone • Desktop Continuity – Same desktop as long as you use VDI • Appliance Computing – Use any desktop or thin client • Security – Same as on campus • Operating System Independency – Run Windows 7 using VDI on a computer with Windows XP, Mac X, IOS or Android operating systems

  10. Why VDI? • Software Standardization – Run same versions of software that are on campus • Remote Printing – Print to campus printers from home • USB Drive Independence – Access I: drive from off campus • Remote Help Desk Support – Help Desk can remote into VDI instance • Green Computing – Thin Clients use 20% of the electricity of a full desktop and take up 1/12th of the space in a land fill.

  11. Advantages of Using Cloud Computing from Home • You can access files stored to the I: drive from home • You can use the Outlook Client. • You can access VWConnect. • If you use the Administrative Information System (AIS), you can now access it from home.

  12. Best Practices • The C: drive and D: drive are different from the physical computer (All data should be stored on I: and J: which would be the same.) • Options, Disconnect and Logoff rather than Shutdown or closing the window. • Ctrl-Alt-Ins (Insert) is used in place of Ctrl-Alt-Del (Delete) (to get to Task Manager or lock your VDI instance). • Responsiveness of the Virtual Desktop is heavily dependent on the Internet connectivity although the computational aspects should be better due to the main processing occurring on a server rather than the physical computer. • Options, Reset Desktop rather than rebooting computer.

  13. Installing the Virtual Desktop

  14. Installing the Virtual Desktop • Open your Internet browser • Enter the address: https://desktop.virginiawestern.edu • If you have the latest version of VMware already installed, it will open up automatically and you can close the browser. • If you are given an option of which version to load, you want the one without the local option. • Press the Download button.

  15. Accessing the Virtual Desktop

  16. Accessing the Virtual Desktop • Double-click on the VMware View Icon. • Make sure the Connection Server is set to desktop.virginiawestern.edu, if your physical computer is not connected to the VW network, uncheck the Log in as current user, then click Connect.

  17. Accessing the Virtual Desktop • If Login as current user was unchecked on the previous screen, you’ll next see the VMware View login screen: • Enter your standard VW Windows/network User Name and Password. • Make sure the Domain is set to VW and click Login.

  18. Accessing the Virtual Desktop • Next you’ll see the virtual desktop connection screen: • First check the Display and make sure it is set to Full Screen or Multimonitor, whichever is appropriate. • Then either double-click on the appropriate selection or highlight it and click Connect.

  19. Accessing the Virtual Desktop • You’ll now see the normal Windows login sequence just as if you were logging into a physical computer on campus. • You will be able to do some customization of your virtual desktop such as adding a few desktop icons and customizing the taskbar, but some things are locked, such as being able to change the Windows background.

  20. First Time Use • If this is the first time that you have used the virtual desktop, you need to initialize your Outlook client: • To do this, go to Start, Email, Microsoft Office Outlook and select it. • Outlook will import your settings automatically. If it asks for your initials, accept what is in the box. It will take a few minutes for all of your email to download. • After the download is complete, you will have full access to Outlook as if you were logged onto a computer on campus. • Also check your I: drive to make sure that the files are the same as if you logged into a physical computer on campus.

  21. Disconnect and Log off • When you are done using the virtual desktop, the best way to end the session is to click on Options on the VMwaretoolbar, then select Disconnect and Log Off, then press Yes when it asks you if you’re sure you want to disconnect and logoff. • If you just close the window or only choose disconnect, the server will wait 30 minutes before logging you off of your session.
