Windows Server 2008 new technology analysis

In the past few years, the Windows Server 2003 server operating system has been welcomed by many SMB users due to its friendly interactive interface. However, Windows Server 2003 has yet to be improved in terms of security and functionality of the accompanying tools. With the release of Windows Server 2008, people are eager to know what improvements the new operating system has over previous generations. Please follow the small series to see the new features of Windows Server 2008!

New website publishing tool IIS 7

Technical Keywords: Command Line Tools, Stability, HTTP Management, Module

Everyone must be familiar with IIS 6 provided by Windows Server 2003. It is an easy-to-use website publishing tool. However, it is because it uses an easy-to-use UI interface, so many network administrators accustomed to using the command to manage the server are inconvenient when performing some advanced operations on the server, and the stability problem of IIS 6 is also affected by many network management. Rickets.

Now IIS 7 integrated in Microsoft Windows Server 2008 has been greatly improved compared to IIS 6. IIS 7 has an appcmd.exe command line tool built in. This command line tool simplifies common use for network administrators. The web server manages tasks and makes the process of some advanced operations easier (this is similar to Apache). For example, we only need to enter a command to list web server requests that wait more than 500 milliseconds, so we can use relevant information to debug those applications with poor performance. Not only that, the stability of IIS 7 is greatly improved compared to IIS 6, basically there is no such inexplicable crash problem with IIS 6.

Previously, we had to remotely log in to the server to manage IIS 6, and then start the IIS program and start the operation. Now, IIS 7's management interface supports HTTP remote management, so you can manage IIS in your browser just like browsing the web. Moreover, since the server is only accessed through HTTP, there is no need to open other ports on the server, which reduces some insecure factors, and also avoids some misoperations after logging in to the server.

IIS 7 also has a brand new feature: a modular installation to build core services. In IIS 6, all features are built-in defaults, making it difficult to extend or replace any of them. IIS 7 consists of more than 40 different feature modules. By default, only half of the modules are installed. Administrators can selectively decide to add or subtract related feature modules. This method is more flexible, which not only greatly saves installation time, but also reduces the number of running other service programs, reduces the attack surface, and improves the security of the server.

Xiaobian Comments: Microsoft has long used a bundled strategy to promote its own system solution, but the bundled software is often abandoned by many people due to its weak function and poor performance. For example, many network administrators choose the website publishing tool. Preference to Apache. The emergence of IIS 7 is a good opportunity for Microsoft to name itself. In many ways, IIS 7 draws on the strengths of its competitors, such as providing command-line tools, which greatly enhances the competitiveness of IIS 7 for further Competition for market share provides conditions.

Multi-purpose virtualization technology

Technical Keywords: WSv, VM, Hypervisor

When it comes to virtual machines, you will definitely think of VMware and Virtual PC. Machine software. After Microsoft acquired the development company of Virtual PC, it integrated Virtual PC into the new server operating system. And after the improvement, it appears in front of everyone in the form of a complete platform of Windows Server virtualization (WSv).

Now, network administrators can use WSv to easily create virtual machines (VMs) to achieve multi-purpose use. This can greatly improve the efficiency of server hardware and save server procurement expenses. WSv allows virtual machines to run on service accounts with only the required privileges, ensuring that the virtual machine operating system does not interfere with the host operating system. This way, even if a virtual machine has a problem, its impact on other virtual machines is limited.

Virtualization technology can turn a server into multiple virtual servers

In addition, Windows Server 2008 has a lightweight low-overhead virtualization architecture based on 64-bit Hypervisor. This architecture supports the virtualization technology's hardware (the corresponding technology of Intel and AMD) to make the virtualized operating system have higher performance. If enterprise users use hardware that supports Hypervisor technology, the performance of the virtual machine can be improved without the existence of multiple virtual machines, and the performance of each virtual machine cannot meet the actual application requirements.

Xiaobian Comments: The virtualization technology of Windows Server 2008 has changed a lot compared to the previous Virtual PC software. It is not just a simple integration of Virtual PC software, but also integrates a variety of features to form a complete platform solution. It solves many difficult virtualization technology challenges, including ensuring the security of consolidated servers (servers running multiple virtual machines), meeting the demands of dynamic workloads, enabling high-performance operation of virtualized workloads, and simplifying Management, etc. It is quite competitive compared to VMware.

Technical Keywords: NAP, BitLocker, CNG

Windows Server 2008 provides a range of new technologies to improve system security, with significant improvements over previous generation server operating systems.

Network Access Protection (NAP) prevents unhealthy computers from accessing the corporate network and causing damage. Enterprise users can use NAP to configure their own client health requirements, and can update or correct non-compliant computers and then allow them to connect to the corporate network. In fact, NAP is equivalent to a software that can evaluate the health of the client. As long as the network management system is configured with a health policy, NAP will work after discovering computers that do not meet the relevant standards, restricting these non-compliant computers from accessing the network and protecting the LAN. Other computers.

In addition, BitLocker Drive Encryption is a new key security feature in Windows Server 2008 that helps protect servers, workstations, and mobile computers. This technology encrypts the contents of the disk, and there is no danger of data leakage even if there is a problem with the server.

CNG, the next generation encryption technology, is a more reliable encryption method provided by Windows Server 2008 than other encryption methods. It provides a highly flexible franchise development platform that allows high-end users to create, update, and use custom affiliation algorithms in other related encryption. CNG uses the US government's Suite encryption algorithm, which includes encryption, digital signature, key exchange and hash algorithm encryption.

Xiao Bian Comments: With Windows Server 2008, enterprises can adopt the policy-based security features such as NAP to control the health and security status of computer connections, which helps to improve the security of enterprise computers. And many new features provided by Windows Server 2008 make the machine with Windows Server 2008 operating system the safest Windows server.

As a new generation of server operating system, Windows Server 2008 not only inherits and perfects the advanced features of the previous generation of operating systems, but also uses many novel technologies, and the integration of components is getting higher and higher. This not only enhances its own competitiveness, but also provides a complete platform solution for enterprise users. As Bob, senior vice president of Microsoft, said, “makes companies invest more in innovation than in day-to-day management and maintenance.”
