Three questions about how Windows Server cloud performance improves

Server08 R2 is the main cloud operating system

2012, the development of cloud computing has begun to descend slowly, after all, the ultimate goal of cloud computing is to bring profits to the enterprise, to bring convenience to people's lives, illusory things even if the outline of the perfect will be eliminated. In 2012, cloud computing has begun to solve the real problem for users, the major IT vendors have launched their own cloud solutions, it can be said that the next step of cloud computing will usher in a real test, but also the cloud is ushered in a rapid landing opportunities.

Cloud computing, the operating system can be said to be its soul, the quality of its services related to the development of cloud computing, and the mention of cloud operating systems we have to mention the Windows Server 2008 R2 in the cloud played a key role, as Microsoft Cloud Platform Windows Azure core operating system, The advent of Windows Server 2008 R2 is a good way to fill the gaps in the cloud computing development operating system, and while various cloud platforms are emerging, cloud operating systems such as Windows Server 2008 R2 are rare.

Windows Server 2008 R2 has a greater performance boost in many ways than the previous generation of Windows Server 2008, enhancing virtualization, System management resiliency, network access, and information security applications, R2, not just to expand the Server 2008 applicability, how to accelerate the popularity of Windows 7 in Enterprise cloud computing with these mechanisms is the play.

Server Core Feature Hardening

The development of cloud computing relies on the process of enterprise virtualization, so the strong performance of Windows Server 2008 R2 in virtualization will contribute to the further development of cloud computing. Let's take a look at how Windows Server 2008 R2 improves performance in cloud computing. as follows:

Server Core Functionality Enhancements

The server core of Windows Server 2008 R2 supports the. NET Framework, so IIS 7.5 features such as asp.net can also be used on the Server Core.

The Server Core installation of Windows Server 2008 R2 can be configured with more roles, for example. NET architecture, IIS 7.5 features such as asp.net can also be used on the Server Core.

In addition, because Server Core supports the. NET Framework, PowerShell is also used on the Server Core. Windows Server 2008 R2 also upgraded PowerShell to version 2.0, which allows you to implement various actions as a command.

At the same time, users can choose whether to install WOW64 in Server Core. Because WS08R2 has only 64-bit versions, you need to call Wow to run 32-bit applications. However, if you are using 64 bits on the server Core, don't install Wow. In this way, Server core takes up less space and there are fewer possible documented security vulnerabilities.

In addition, the Hyper-V Server Management tool Sconfig tool is introduced into the Server core of Windows Server 2008 R2. The tool can simply control the firewall port on Server Core.

Server Core Benefits

1, improve the stability of the server

Server Core installs only the features that are required to manage DHCP, DNS, file servers, or domain controllers, and only a small number of services and applications are running on Server Core. As a result, Server Core greatly enhances the stability and performance of servers compared to servers that run more features.

2, reduce the amount of software maintenance

Server Core installs only the most basic features to implement the server roles of DHCP, DNS, file servers, and domain controllers, so it is more manageable and reduces software maintenance, at least not so many software needs to be updated and patched.

3, reduce the risk of attack

Because limited services and applications are installed on the server, the number of attack points exposed to the network is limited, resulting in fewer attacks. At the same time, if a vulnerability is found in an application such as IE, it is not necessary to install the relevant patches because the server does not have an application software such as IE.

4. Less space occupancy

With the exception of unnecessary drivers, applications, and graphical interfaces, Server Core has only about 1GB of installation size, is 1/6 of the normal Longhorn server, and after the installation is complete, because of less application, the server's resource share will be reduced. Because the Server Core installation version is a subset of the Longhorn server, only files that implement these four roles are installed. For example, in Server Core, IE will not be installed. NET Framework.

Management of the Server core installation will also vary. Because it does not have a traditional graphical interface, Server Core requires an administrator to configure the system on the command line. Once the configuration is complete, the administrator can administer the server at the local or remote terminal command line. Server core Promotion helps users deploy cloud computing solutions more quickly, and makes the system more stable, safer, and less space-efficient, well suited to the needs of cloud computing.

Increased IIS 7.5 features

Ii. Increased IIS 7.5 features

In IIS 7.5, IIS administration Pack for IIS 7.0 is integrated in Windows Server 2008 R2, which enhances FTP functionality, IP The stickiness feature can access client PCs and load balance by connecting to a Web server.

The new DHCP failover feature is also integrated into Windows Server 2008 R2, which improves DNS security by migrating to new systems after DHCP failure and blocking attacks on DNS.

In addition, Active directory-related features are also enhanced. For example, new PowerShell can enable users to manage active Directory more quickly and efficiently. Therefore, PowerShell can handle all the complex operations, including batch programs.

Windows Server 2008 R2 also simplifies Active Directory association functionality, adding offline join domain functionality. Now, if you are registering a client PC in a domain, you must connect to the domain server online. However, this requires the creation of a client PC environment, with the ability to join the domain offline, if a domain-registered XML file is created, the client PC can also be registered offline.

In addition, Windows Server 2008 R2 adds the Best Practices Analyzer feature, which automatically checks Windows Server 2008 R2 Active Director, DNS, IIS, Remote Desktop service and other settings. In short, this function has played a role in enhancing WS08R2 security.

Because Windows Server 2008 R2 is based on Windows Server 2008, managers do not have a poor sense of compatibility during migration. Windows Server 2008 R2 has an obvious advantage because of the increased functionality within the Windows Server 2008 R2.

Migrating to Windows Server 2008 R2 is important for users who have migrated to Windows Server 2008 just over a year ago. However, for those users who use Server 4.0, Windows Server and Windows NT have great benefits, so they can consider migrating slowly to ws08rs.

In the face of cloud computing, customers, whether building Web servers, FTP servers are more heart applications, so that the operation in the cloud more quickly and conveniently.

Hyper-V 2.0 update

III. update of Hyper-V 2.0

Hyper-V 2.0 supports live migration dynamic transfer and enables more Linux operating systems to be installed on VMS.

Six months after the launch of Windows Server 2008, Microsoft launched the virtualization platform Hyper-V 1.0, built on Windows Server 2008, which has basic virtualization capabilities but is relatively weak compared to other virtualization platform features, For example, the lack of dynamic transfer capabilities makes it impossible to transfer VMs to other entity servers without stopping the virtual host (VM). This functionality is supported by the Hyper-V 2.0 on Windows Server 2008 R2, making this virtualization platform a significant step forward.

New Hyper-V 2.0 features:

Support Live Migration Dynamic migration

Can dynamically adjust capacity on virtual disks

Dynamic configuration of VM memory

Ability to boot on entity host with virtual image file

VM-supported operating systems add Red Hat Linux

The main control (host) supports up to 32 processor logical cores

Improve VM Computing Efficiency

If the Windows Server 2008 R2 is the core of the cloud platform, then Hyper-V 2.0 is the most important part of the core, and the presence of Hyper-V 2.0 not only takes a big step in virtualization, but also gives cloud platform users the faith to use Microsoft cloud computing, With the continuous introduction of Hyper-V, Microsoft cloud Platform will become more and more popular.

Enhancements to Domain functionality

Iv. domain functions

To use some of the new features in the Enhanced Active Directory (ActiveDirectory), the user's domain server must be running on top of the new functionality layer, and among these new features is the ability to join the domain. During deployment, users do not have to manually join a domain, but can build an answer file that can be joined to a domain as appropriate. In fact, the computer does not even have to physically connect to the network to join the domain at deployment time and become a configured member of the domain after the reboot. This feature is important for remote deployment, especially as organizations are increasingly using distributed, and remote deployment of servers around the world becomes a basic requirement for network configuration. The new Active Directory Recycle Bin is also an excellent feature that when an administrator deletes an Active Directory object, the objects are moved into the Recycle Bin and can be easily restored if they are later needed.

In the R2 version, Terminal Services has a new name for Remote Desktop Services (remotedesktopservices), and the new features are impressive in RemoteApp, which allows you to remotely connect to applications on the server, And can be run like an application on a local server. Such a connection is achieved through a Remote Desktop protocol. By RemoteApp, it will be easy to publish applications to the server.

In addition to a single application, users can send entire desktop clients to the server through Remote Desktop services. The client application published to the server is not much different from the user's local desktop project, and users are not even aware that the application is not a native program. Remote Desktop Services Narrow the distance between the installed local application and the server program that serves it.

V. Super Script

The upgraded PowerShell will also be released as part of the R2. PowerShell2.0 adds a new cmdlet command line and some important features, two of which are especially important.

The first is remote access, PowerShell2.0 can implement remote call and script operation of the server, just as the user is in the console.

Another important feature is transaction processing, in which the user can annotate any of the steps in a specified long script, and all steps can be rolled back at the same time. The good thing about this is that the user writes a script that does a lot of the action, and if one of the steps fails, all the steps are rolled back to keep the server and data clean. WINDOWSSERVER2008 has already applied transaction processing on TRANSACTIONALNTFS, and now PowerShell is supporting it and breaking the restrictions.

WINDOWSSERVER2008R2 further perfects Servercore by joining IIS and supporting. NET Features. WindowsServer through the combination of real-time migration with hyper-v2.0 and virtual machines, the performance of the system is greatly improved, while TerminalServices users will also be applied to the enhancements of Remote Desktop services. For large service providers, organizations with large networks, and businesses with a large number of virtual machines, WindowsServerR2 is likely to be a concern and a solution for them.

Finally, the Windows Server 2008 R2 provides only 64-bit versions for the first time and no longer supports 32-bit environments, and to sum up, it is easy to see that the new features of Windows Server 2008 R2 are designed for the development of cloud computing, visible, Microsoft has worked hard enough on cloud computing, and Windows Server 2008 R2, which is now Microsoft's best cloud operating system, can help Microsoft move into the cloud.
