Speaking of virtualization, this topic is a very interesting topic.Virtualization virtualization solutions from the virtual to the completion of construction, said it is not complicated.We learn from Microsoft's virtualization solutions to give you clear answers to what is virtual in the end.
Microsoft's virtualization solutions can be said a technical package to achieve an integrated, end to end, virtualized infrastructure, through the different levels, from the desktop to achieve the full range of data center management, and therefore can doto fast on-line solution, fluid effects and the use of disaster recovery services and data backup and recovery, greatly enhancing the usability and stability.In particular, the data center is attractive and friendly desktop management (end-users and administrators will enjoy the convenience it brings) the use of results, a series of Microsoft suite of data center can achieve dynamic configuration, and dynamic resource allocation.
Give a simple example, a company has two servers, each running two database applications, the peak at different times, so if you want the implementation of two applications were increased processing efficiency, we must re-purchase two servers, so thatcan ease their peak, respectively, to avoid downtime caused serious consequences of excessive data;
If you use Microsoft's virtualization solutions, or the two sets of server equipment, data processing from the two sets of servers (either physical servers or virtual servers) each other between the flexible allocation of resources, peak values of their respective assessments, and caneach other disaster recovery, saving the purchase cost of hardware, but also the application of enterprise data management software and improved the life of a high degree, its own encryption and recovery technology, but also enables enterprises to physical servers and virtual serversdata on the last one under any circumstances have a solid guarantee.
Microsoft's virtualization architecture is divided into a total of five levels:
1. We start with the "server virtualization" to begin with:
Traditional virtualization: the virtual machine we see the hardware devices are being emulated, when the upper layer after the request is handed over to the virtual machine will go through a conversion, after the physical server and then to us, therefore, the systemthe performance and speed will be affected, and this is the reason why the traditional virtualization solutions is relatively low coverage of one of the reasons.
So Microsoft is how to solve this problem, for the HyperV, it can be called a state of semi-virtualization, the virtual part to see the virtual hardware device is not being out, but by HyperV structure, directaccess to the hardware, the request directly to the server, because the middle of a conversion reduced, so the calculation speed can be improved access to breakthrough performance of the original application of the virtual bottleneck.At the same time in the virtual machine and there is no compatibility between hardware problem, because Microsoft's HyperV is allowed to install in a virtual machine hard drive, so that the use of the virtual machine operating system and the use of the physical machine operating system, you do not have muchdifference, as long as different for different drivers for hardware installation compatible use, thus eliminating part of the technical staff of the compatibility concerns.
So, HyperV out "windows server 2008 - HyperV", made for a separate product, this is based on what end? Is to enable users to have more choice, the use of two different environments, if the user needshas a complete and comprehensive virtualization architecture, then he can choose to windows server 2008 - HyperV, and if the user
Only one platform virtualization solution to run a virtual machine running the service, it only need to select HyperV, to give him a platform to establish such a can, which is Microsoft's virtualization solutions in the management and user match the characteristics of the twoshow.
2. Next, we look for the "desktop virtualization"
In fact, the concept of desktop virtualization is simple, Microsoft's other virtualization concepts and the concepts are different, Microsoft's desktop virtualization is the operating system and application package, uniform issued to the user, Microsoft is more the concept of classificationfine only.
3. Virtualization application:
Application virtualization is different from the physical machine virtualization, virtual physical machine is a machine of all content on the package, and application virtualization is the entire application and all documents required for packaging, before the user application needsinstallation, the local will have many files, system files will be rewritten, the impact on the user's own system; and publishing application virtualization is a data packet to the user, and contains all the content the user needs no installation, similar to the traditional"green software", the same time, administrators can easily control the back-end distribution of data packets, such as time, authority, the corresponding relations, management tools and more abundant, but the user's experience has not been any impact,end users will not change any habits.
For businesses, the most important benefits is to reduce management costs and IT staff workload, "application virtualization" allows administrators to manage the server only, and the entire enterprise IT management will immediately fall into place.
4. Desktop Management Suite: MDOP
MDOP includes several parts to simplify the Windows environment, application deployment and management, and thus your desktop infrastructure optimization.The key is Application Virtualization implement application virtualization solutions, while other programs will assist managers to better manage IT architecture, such as Advanced Group Policy, the client's operation and maintenance mechanisms, are included.
5. Presentation virtualization solution: Terminal Service
Terminal Service is a central expression of the architecture, the user, when used, is to log on to the remote server, all applications that operate in the remote transmission to the server is only keyboard and mouse commands, and users only getchanges in interface.
These are the Microsoft virtualization solution technical architecture (four), we can understand from the data center to the desktop package, In addition, Microsoft established an assessment center for customers, there is a reference manual of best practices, including the complete tooland documentation, companies can easily yourself in order to assess their state of the business, it is recommended that you are doing virtualization solution before the migration, do first about this assessment.
