Practice: how to deploy the RemoteApp server (multiple images) (1)

Virtualization technology is one of the most popular IT technologies today. Virtualization technology is widely used in improving hardware resource utilization, O & M efficiency, and user experience. Microsoft plans virtualization technology as server virtualization, desktop virtualization, application virtualization, and presentation layer virtualization. Today, we will introduce RemoteApp, a new technology in layer virtualization.

What is RemoteApp?

The predecessor of RemoteApp is the terminal server. The terminal service technology is a mature and widely used technology. Clients can connect to the terminal server, execute applications on the terminal server, and then send the execution results back to the client. In this way, when the client is subject to certain conditions and cannot deploy some applications on the local machine, you can run the program using the terminal server. The operation is completed on the server, and the client is only responsible for the input and output. With the terminal service technology, many computers with old configurations have gained new vigor. It should be said that the terminal service technology has played a major role in improving the utilization of computer hardware.

The terminal service technology also exposes some shortcomings to be improved in the application process. For example, after a user connects to the terminal server on the client, a server desktop is obtained. For users familiar with the client operating system, Server Desktop is not the best choice. What's worse, beginner users often need to switch between the local host desktop and the Remote Terminal Server Desktop. They need to run applications on the terminal server desktop, but also need to send and receive emails on the host desktop to browse the Web page. If a user needs to connect to multiple terminal servers at the same time, the situation will be more complicated. inexperienced users may be confused when switching between the desktop of multiple terminal servers and the host desktop, the error probability increases greatly. Also, when a user wants to connect to a terminal server over the Internet, the user must first access the Intranet through a VPN. However, when a user is on a business trip outside China, some Internet access points may not enable the communication ports of PPTP or L2TP. As a result, the user cannot connect to the terminal server through VPN, affecting normal service usage.

RemoteApp has improved the terminal service technology. In RemoteApp, when you run applications on remote servers on a client, you no longer need to get the entire server desktop. You only need to see the window where the application is running! Apps in the RemoteApp are integrated with the client desktop. There are entries in the taskbar and they run in their own windows. They look like local programs in the client. If RemoteApp and TS Gateway are combined, you can access the application in RemoteApp through port 443 without establishing a VPN connection. Roaming users and mobile users are the biggest beneficiaries of the RemoteApp, because no matter which computer they log on to, they will be pleasantly surprised to find that the required application has been "installed" and can run directly. In addition to the above advantages, compared with the terminal service technology, RemoteApp significantly reduces the consumption of network resources, because RemoteApp only needs to display the running window of the application, you do not need to display the desktop of the entire Terminal Server completely.

To help you better experience the RemoteApp, we have prepared an experiment environment to introduce how to deploy, configure, and release the RemoteApp. Shows the experiment topology. Three computers are used in total. One is the domain controller and DNS Server, the operating system is Windows Server 2003 SP2, the other is the RemoteApp Server, and the operating system is the latest Windows Server 2008 R2; another client uses the XP SP2 operating system. First, we will introduce how to deploy the RemoteApp server.
