Windows Server 2008 new features analysis

February 2008, for the Chinese people is a mixed month, mixed feelings of a month. The Spring Festival, Lantern Festival, and Valentine's Day bring people a joy and warmth; the heavy snowfall in the South brings huge losses, and the stock market decline has made many people unhappy. And don't care who is profitable and who is sad, we turn our attention to the software giant Microsoft. On February 27th, Los Angeles, the most important enterprise platform release in Microsoft's history will be held as scheduled. Windows Server 2008 will be released together with Visual studio 2008 and SQL Server 2008. Here, the author leads everyone to take a quick look at the new features of Windows Server 2008 in a relaxed and concise language.

When Microsoft released Windows Server 2003, it put forward the slogan "How fast is it, and it is stable and stable." More, refers to more innovation, adding a lot of functions; fast, refers to short development cycle, rapid development, rapid deployment; good, refers to good stability; province, refers to low total cost of ownership, save money.

The upcoming Windows Server 2008 is an enterprise-class application platform that provides better and stronger support for enterprise applications such as CRM. Its new features can be summarized into four areas.

A Solid Platform

Windows Server 2008 is the most stable platform in Microsoft history, providing excellent support for all applications; and its manageability is very High, allowing users to manage systems and applications with minimal effort. Applying a Microsoft employee, "This is a revolutionary server platform." In this feature, it mainly includes the following five important functions: Server Manager, Powershell, WDS, Cluster, and ServerCore. Here I want to focus on the two functions of Powershell and ServerCore.

Powershell is a script program. The server platform is aimed at two groups of people, IT Pro and developers. IT Pro may not be a programming expert, but at work, you need to do some work with some simple programs. For example, if you need to deploy Office across the enterprise, you need to collect information first and see if the hard disk space is sufficient. With a large number of companies and huge data, you can use a small script to help collect this information. Powershell is such a tool that provides IT Pro with a scriptable interface that can be developed and executed automatically on a computer. In this way, IT Pro can implement simple tasks for network management in system management. Powershell is a command line interface with an interface similar to DOS that supports batch execution and remote control.

ServerCore is an option when installing the system. If this option is selected, the system does not have a graphical interface, that is, there is no icon on the desktop, no start menu and taskbar, no right button function, only blue. A colored background with a command line window. With this option selected, the system only installs the core of Windows and only contains kernel-related components. IE, Outlook, Mediaplayer, etc., which are not commonly used on the server side, will not be installed. There are many benefits to doing this.

First of all, the occupied resources are very small, 1GB of space is enough to install.

Secondly, the installation is fast, only 30-40 minutes.

Third, there are no redundant components, and the post-maintenance needs to be patched less than other servers, which is 60-70% less than the average Windows Server patch installed in normal mode;

It is very safe and stable, because there are not so many services, and there are fewer attacks. There are no components at the same time, and the operation is more stable.

Of course, Server Core mode also has its own shortcomings, not all services can run under Server Core, only some specific services, such as virtualization, Active Directory, etc.

2 Very good web support

Many companies have such a need, need a good web support platform, and hope to put the content of the enterprise on the portal or e-commerce website. As a result, Windows Server 2008 has many enhancements to the Web. Mainly used in document publishing, information sharing, Sharepoint Services 3.0, IIS 7.0, Windows Media Services and so on. Compared with the previous version, IIS 7.0 has made a great improvement in the kernel. The kernel is divided into more than 40 modules. The administrator can choose to open some modules and close some modules according to different requirements, so that the administrator can control the system more. easily. In addition, the stability has been greatly improved, IIS 7.0 will monitor its own system, when an exception occurs, such as occupying too much content, taking up too much CPU resources, IIS 7.0 can do automatic optimization.

Three built-in virtualization technologies

Windows Server 2008 supports built-in virtualization technologies, including server virtualization, application virtualization, desktop virtualization, presentation layer virtualization, and centralized management. aspect. Among them, server virtualization technology enables virtual servers to run on Windows Server 2008. Hyper-V technology can ensure that the efficiency of virtual servers is very close to the efficiency of deploying the same physical servers separately.

Windows Server 2008 virtualization technology is multi-layered to help users cut costs. For example, if you need to achieve high availability, the original method is to double-click hot standby, deploy two servers, the main server processes data, and the backup server is in the state of Stand-by for a long time, which is a great waste of resources. With virtualization technology, you can deploy on the same server, greatly reducing this waste, reducing costs and increasing flexibility.

Four Flexible Security

Windows Server 2008 provides enhanced built-in security features, including BitLocker, RMS, Enhanced Firewall, RODC (Read Only Domain Controller), and NAP (Network Access Protection). )several aspects. BitLocker is a function that encrypts the entire disk and is also available in Vista. RMS manages all Office documents. Even if the document has been sent to others, it is no longer in the hands of the owner, and the owner can still control how the document is accessed by others. The built-in enhanced firewall is very powerful. Administrators can set different security policies according to different networks. For example, the security policy may be different between the home environment and the office environment. RODC is suitable for companies with branch offices, and the physical environment of some branches is not secure enough. This function can ensure security in this case.

The advantages and disadvantages of the new system, the user has the most say. Whether Microsoft's next-generation enterprise platform can be accepted by users, let us wait and see.
