Windows 2008 Enterprise Centralized Application Access

Before talking about server high availability, virtualization was mentioned because enterprises are increasing the risk of servers and applications while implementing virtualization, so high-availability solutions are needed to reduce This risk. We also talked about the future development of server is a virtualization, the continuous development and progress of virtualization technology, reducing costs for enterprises, improving the efficiency of server use, and enhancing the productivity of enterprises.

Virtualization actually includes several levels:

1. Server Virtualization

2. Application Virtualization

3. Desktop Virtualization

4, presentation layer virtualization

In these levels of virtualization solutions, Microsoft also launched the corresponding products, such as Microsoft VirtualPC to achieve desktop virtualization; VirtualServer2005 to achieve server virtualization, etc. as follows:

also will be discussed later in detail in the WindowsServer2008 server virtualization technology, we first discuss the presentation layer virtualization. In many enterprise customers, there is a need to centrally manage and access applications, especially for applications that are frequently updated and not easily deployed to clients. When applications are frequently updated, companies are often reluctant to deploy these programs directly to the client, because for IT staff, deploying applications for all clients and constantly updating them is undoubtedly time-consuming and labor-intensive. So many companies put these applications centrally on the server, allowing users to centrally access them. Terminal Services in Windows Server just provides users with such functionality, but there are some problems with Terminal Services in Windows Server 2003. For example, the client uses Remote Desktop to connect to Terminal Services and needs to use port 3389, and 3389 is often known. The port being attacked, so many enterprises will shut down port 3389 in the firewall. If employees are not on the internal network of the enterprise, it is difficult to access these applications. They have to use VPN to connect to the intranet and then access the application. low.

So what are the benefits of Windows Server 2008 Terminal Services?

1. Quickly deploy applications that are frequently updated, frequently used, or difficult to manage.

2, you can seamlessly access a separate application without having to access the full remote desktop, the remote application is integrated with the user's local desktop, and the user can use the remote application just like a local program.

3. Reduce the complexity of users, partners, and clients accessing programs.

4, comprehensive security configuration, can protect the internal resources of the enterprise.

5, you can use HTTPS to access applications through the Internet, no longer need to use VPN or open port to connect applications.

6, users can easily connect to TerminalServer and remote desktop across firewalls and NAT.

7. Optimize the bandwidth in network transmission.

8. For branch users, it is easier to access enterprise resources.

It is not difficult to find that Windows Server 2008 terminal services have changed a lot compared to Windows Server 2003. These changes have made it difficult for enterprises to implement TerminalServices. We also implemented WindowsServer2008 TerminalServices for a large enterprise not long ago. I feel the power of it, and I will share some of the experience in using, deploying, and testing terminal services later.
