Prepare and Manage Remote Applications through Virtualization
- 1. Principles of Virtualization Prepare and Manage Remote Applications through Virtualization Date: Department of Computer Engineering Jain Group of Institution, Bangalore Presented By: Rubal Sagwal Assistant Professor Department of Computer Engineering 1ADAD
- 2. Contents • Prepare and manage remote applications: • Configuring application sharing • Package applications for deployment by using RemoteApp • Installing and configuring the RD Session Host Role Service on the server ADAD 2
- 4. Virtualization Technology Most of the organizations have started using virtualization technology in their environment – why? • Provide various advantages. • Problem: IT industry spends most of the money for maintenance. • Solution: If we use virtualization, we can reduce the maintenance cost. • Example: Instead of having ten physical server we can have one physical machine and run ten virtual machine on the server. It reduces the power consumption as well. ADAD 4
- 5. Contd… Virtualization Technology • Most important advantages in virtualization technology – provide solutions to reduce down time. • So, it leads to high availability. • Virtualization makes operations simpler. • The virtualization technology can available as server virtualization, desktop virtualization, application virtualization, network virtualization. ADAD 5
- 6. Application Virtualization • The most recent addition to IT virtualization is Application virtualization. • App virtualization lets, the user to utilize and access the application without installing it on their local machine. • This technology detaches the installation of application from the machine which is accessing it. • Virtual applications are packaged and sent to the end user’s computer in such a way that the applications will not disturb anything which is already running on the computer. ADAD 6
- 7. Application Virtualization • We can reduce the workload on the client computer with app virtualization because the application is not installed on the local machine and in remote app virtualization the application is not running on the local machine. • There are two types of application virtualization: 1. Remote 2. Streaming ADAD 7
- 8. 1. Remote Application Virtualization • In RAV, the application will be running on a remote server - using network connection the user can access and run the application from the local machine. • The remote app virtualization relies on a remote display protocol. • The seamless windows technology allows the applications running in the remote machine to be fully integrated with the local machine. So, the application will behave as if it is installed on the local machine. ADAD 8
- 9. Contd… 1. Remote Application Virtualization • Constant network connection should be maintained for the functioning of remote app virtualization, because the end user’s local machine is accessing the application using the network connection. ADAD 9
- 10. 2. Streaming Application Virtualization • In SAV, when an end user requests for an application, the components which are required to run the application are downloaded to the end user’s local machine, then the application is executed in the local machine. • Only the components which are required to run the application is downloaded initially. • The remaining component will be downloaded when it is required. Once, the components are fully downloaded the end user can access the application without network connection. Because the application is running in the local machine, when the application is closed all the files that are related to the application are removed from the local machine. ADAD 10
- 11. Advantages 1. Decreased system impact – When we use application virtualization the application is not installed in the client machine. The application related data and files are not stored in the local machine. Everything is stored in the server. Even in the streaming app virtualization when the app is closed all the application related files are removed. So, we can save the storage space in the client machine. The application is not directly run on the local machine. So, it also saves the processing power. ADAD 11
- 12. Contd… Advantages 2. No Conflicts - With Application virtualization, from a client computer users can access multiple versions of the same application at the same time without any conflicts. For example, in your organization every user is using an application that will support only Windows 7 OS, now you want to upgrade all the machine to Windows 8 but the application will not run on the windows 8 OS. In this situation the app virtualization is very useful. ADAD 12
- 13. Contd… Advantages 3. Extended application lifespan – we can run the old applications which is not supported by the newer operating systems. 4. Extended hardware lifespan - The newer applications require more processing power and high configuration machine. If we want to use this application, we need to upgrade the hardware of the client machine because the older client machine has low configuration, but if we virtualize these application then we can run it on the older desktops which has less configuration. ADAD 13
- 14. Contd… Advantages 5. Efficient updates - At the server level, all system patches and updates are done once, when applications are virtualized. No need to update each machine separately. 6. Full portability - Virtualized applications can stream from any network share without a local client or a backend server. ADAD 14
- 15. Disadvantages 1. Server dependency - We need at least one host server for application virtualization – need Virtualization software that must be installed on the server before we can virtualize any application. 2. Peripheral devices - Applications that interact with local scanners and network devices may not work properly because it is not running on the local machine. ADAD 15
- 16. Contd… Disadvantages 3. Device Interaction - Since USB drives don’t work with virtualization software, we cannot virtualize the application which requires the use of an attached storage like smart card. 4. Multimedia - We cannot virtualize the application which requires multimedia hardware. • All the computer programs cannot be virtualized. For example, applications that require a device driver. • It is difficult to virtualize the Anti-virus programs and those applications which require heavy operating system integration, like, Window Blinds and Style XP .

- 17. Prepare and Manage Remote Applications ADAD 17
- 18. Prepare and Manage Remote Applications – How • With the help of remote administration features of the Windows – one can manage the applications of all the systems from a remote server. • One can access the computers of our organization from a remote server and install application, modify application and delete application on the remote machine by using the Remote Desktop Snap-in. • In addition to that one can assign or publish applications. ADAD 18
- 19. Prepare and Manage Remote Applications • One can assign an application to the users or to the computers for the access of each person to have the application on their computers whenever needed. • When you want the application to be available to the users you may publish any application to the users in the group and they will have the access to the application whenever necessary as you publish the application to them. • These users then determine when to install the application. ADAD 19
- 20. To create a new connection to a remote computer : 1. Open the Remote Desktops snap-in from your server. 2. In the wizard right-click the Remote Desktops. 3. Then Click Add new connection. 4. In the Add New Connection wizard, in Server name or IP address, specify the name or IP address of the server. 5. In Connection Name, specify a name for this connection. This step is optional you can continue without specifying name. 6. If you do not want to connect to the console of the server, uncheck the Connect to console check box. 7. Click OK. ADAD 20
- 21. To publish an application to users: 1. Open the Group Policy Software Installation wizard. 2. In the details pane, right-click, New and then click Package. 3. In the Open wizard, select the Windows Installer package that you want to published and click Open. 4. In the Deploy Software wizard, click Published. ADAD 21
