Most people do not understand the knowledge points of this article "what are the functions of Windows Server2012?", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "what are the functions of Windows Server2012" article.

Virtualization and storage benefit

Bill Laing, co-vice president of Microsoft Server and Development tools, highlighted the scalability of Windows Server 2012. According to its introduction, Windows Server 2012 can virtualize more than 90% of SQL databases. Judging from the data he gives, Windows Server 2012 can support 8000 virtual machines per cluster, and the industry is currently *. The Software defined Network (software defined networking) feature, which helps users isolate workloads on a shared infrastructure, is also of concern. On the storage side, Laing says users can build storage pools using industry-standard hardware.

Jeff Woolsey, a project manager in Microsoft's server and cloud computing department, introduced Windows Server from a server perspective, saying that Windows Server supports servers with up to 320 logical processors, 4Tb memory and 64TB virtual disks. In addition, Windows Server 2012 optimizes Hyper-V for real-time migration, allowing users to migrate between IP subnets. Live Jeff demonstrates real-time migration of virtual machines from Seattle to New York, where real-time migration was usually limited to the same server, and the introduction of Windows Server 2012 made migration between clusters possible.

It is reported that the shared real-time migration function of Server 2012 can update and patch the system without affecting the service. At the same time, the automation of Windows Server 2012 can also help users add more than 2400 PowerShell command lines. In addition, its extended file server function can automatically switch in case of node failure.

Improvements to IIS 8.0 and .NET 4.5

Windows Server 2012 optimizes its native IIS 8.0 (Network Information Service) to support a multi-tenant cloud. Users can dynamically expand the number of servers over the network and take advantage of the limitations of CPU to provide better isolation. At the same time, IIS 8.0 provides better management for the Security Socket layer.

In addition, the .NET Framework 4.5 provided by Windows Server 2012 adds support for asp.net 4.5, HTML 5, as well as Web APIs and WebSockets, to better support asynchronous programming. At the launch, the project experience Scott Hunter demonstrated how to use mobile devices to modify the code of app.

Support for BYOD and VDI

With the popularity of smart mobile devices, BYOD has become the trend of corporate office, Microsoft's launch of Windows Server 2012 can not do without support for BYOD. It is reported that the key to BYOD support lies in Active Directory. According to Brad Anderson, vice president of management and security at Microsoft, Microsoft can provide everyone with a secure and manageable office anytime, anywhere. Through the direct access technology in Windows Server 2012, we can help devices around the world access the network, and then use Microsoft's dynamic access control technology to control the access content, including access rights and content.

Windows Server 2012 adds support for VDI (Desktop Virtualization Infrastructure), which can be set through "13 Clicks" and System Center Configuration Manager.

Microsoft OEM vendors have launched hardware products that support Windows Server 2012 systems, including Acer, Dell, Fujitsu, Calendar, Hewlett-Packard, and IBM and NEC. It is reported that there will be four versions of Windows Server 2012: datacenter (data Center Edition), Standard (Standard Edition), Essentials and Foundation (basic Edition). The Essentials version has not yet been released and is expected to be available by the end of the year.

Microsoft has imposed restrictions on the license of Windows Server 2012 for Datacenter and Standard. The difference between the two versions is that the DataCenter version of Windows Server 2012 does not limit the number of virtual machines, of course, it is still subject to the configuration of the hardware, while each license of the Standard version is only allowed to run two virtual machines.

The above is about the content of this article "what are the functions of Windows Server2012?" I believe we all have a certain understanding. I hope the content shared by the editor will be helpful to you. If you want to know more about the relevant knowledge, please pay attention to the industry information channel.
