Windows 2008 plays the ultimate music of 32-bit system

Longhorn, the development code for Microsoft's next-generation server and desktop operating systems, was introduced a few years ago. As early as July 2005, Microsoft renamed its next-generation desktop operating system to Windows Vista. It was launched at the end of November 2006. In contrast, the server version has been half-baked.

Finally, Microsoft officially announced at the Worldwide Partner Conference in July 2007. The Microsoft server operating system Windows Server 2008 will be officially released on February 27, 2008 in Los Angeles, USA, and the new products will be released in the new version of Visual Studio and SQL Server.

Virtualization Enhancement

First, let's take a look at the improvement of server virtualization in Windows Server 2008. In Windows Server 2008, Virtual Server 2005 will be replaced by Windows Server virtualization (WSv). WSv contains many difficult virtual solutions. The ability to challenge the dynamic addition of the processor, that is, users can add idle processor resources to the virtual at any time as needed In the machine.

At the same time, WSv can also support dynamic hardware addition. Users can dynamically add/delete resources such as memory, network adapter and memory. This function is convenient for users to accurately allocate WSv host processing capability. WSv also has Many highlights, such as support for the Linux operating system, page file sharing between virtual machines, virtual machine network boot, hot backup of virtual machines through Volume Shadow Copy Service (VSS). Moreover, WSv It also supports virtual machine browsing and data for the parent server.

For some large IT groups with many services and complex application environments, WSv solves the role separation problem on the merge server, which allows the virtual machine to have only The required permissions are run under the service account to simplify the operation and protect the host operating system. In addition, WSv can also provide hot migration, which means users can migrate a running virtual machine from a physical server. Go to another physical server without interruption (whether this feature can appear in the original Windows Server version, it is not yet).

Simplify the installation process

Another exciting feature of Windows Server 2008 is the Server Core, which provides a streamlined installation that allows users to install without a graphical interface. Administrators can Choose to install a minimal installation with specific features but no unnecessary features.

We noticed that WSv is a usable program under the server core, which will greatly reduce the cost of user usage. Previously if the user If you want to install the operating system in a virtual device, you need to purchase related applications, such as VMware, and now use the free WSv virtualization program to save users some overhead.

Terminal Services Enhancements

Windows Server 2008 follows the pace of Windows Vista. Users can access Terminal Services using Remote Desktop Connection 6.0. The program supports horizontally spanning multiple monitors to form a large desktop, but the highest resolution is 4096×2048. Also supports display ratios of 16:9, 16:10, etc. If you install the desktop experience in Windows Server 2008 (Desktop Experienc e) Program, users can use desktop theme, photo management and other functions in remote connection.

Terminal Services RemoteApp is a new remote application display method provided by Windows Server 2008, which is a terminal service display method. In addition, the entire remote desktop can be displayed in the window to the user accessing the application. That is, the remote program running display will be very close to the local program. Moreover, RemoteApp only maintains a central application on the server, which can reduce the server. Workload.

With the Terminal Services Web Access (TS Web Access) service, users can access the Terminal Services RemoteApp program through a web browser without installing any software.

domain control has improved

active directory also has some improvement .Windows Server 2008 provides a new, more comprehensive The domain controller installation wizard, and can restart the Active Directory domain controller without restarting the server.

The most interesting new feature should be a read-only domain controller (RODC). The RODC contains a read-only portion of the Active Directory database that provides easy access to domain controllers whose physical security is not guaranteed. In the past, remotes often failed to provide adequate physical security for a writable domain controller. If the user has to connect to the domain controller for authentication across the WAN, security is not guaranteed. The RODC provides secure access by providing a read-only copy of the Active Directory database.

Or ordinary users, there is no permission to modify the Active Directory database through a read-only domain controller.

Users can read almost all information by connecting to the RODC. However, if not through Remote Desktop (Remote Desktop When connected to a writable DC, no write operations can be performed. RDOC plays a major role in maintaining the security of the domain controller and managing remote servers dispersed in the branch office environment.

Modular Web Services

Internet Information Services 7 (IIS7) has also been improved to some extent.

IIS7 has a modular design, consisting of more than 40 separate functional modules. Users can choose to install according to their needs and save time by limiting the functions that need to be managed and updated. Moreover, since unnecessary software is not running, the attack surface of the Web server is reduced, and security can be improved.

IIS7 New management tools are also available to provide support for IIS and ASP.NET configuration settings, user data, and runtime diagnostics. The manager interface supports remote management via HTTP, allowing for local and remote management without requiring Security is also improved by opening the management port in the firewall. IIS7 will adopt a distributed configuration model that allows users to specify configuration settings for websites or applications in the directory where the code and content are stored. And by specifying the configuration in the file Settings that allow the administration of web applications or website features to be delegated to others.

In addition, IIS7 is said to monitor web servers and view detailed real-time diagnostic information through built-in diagnostic and tracking support. To help users identify the problem and solve it.

Link: New and old operating system comparison

with Windows Server 2003 Than, Windows Server 2008 uses the automatic repair NTFS technology. In the event of a file system error, the server will only temporarily be unable to access some of the data, the overall operation is basically unaffected, and can be automatically repaired without shutting down the server. Another big innovation is that Windows Server 2008 provides options for installing graphics drivers, DirectX, ADO, OLE, etc.

The current test version of the operating system can handle 8 programs, and the final version will be available. Handle more programs, such as file servers, domain controllers, DHCP servers, DNS servers, etc. In this way, Windows Server 2008, like Unix and Linux, can provide the role of DHCP and DNS servers in a protected environment. Features, which greatly enhance the competitiveness of Windows Server 2008 in the server system market.
