Desktop cloud and cloud desktop are different emphases of the same object. Compared with the traditional pc, the big main box is replaced by some small boxes, similar to TV set-top boxes, in which the mouse, keyboard, monitor and network cable are inserted. The desk in the computer room is much more spacious.
Main features:
1. The local terminal is just a display device.
2. Management is centralized. IT engineers manage hundreds of virtual desktops through the control center. All updates and patches only need to update a "base image".
3. In the desktop cloud solution, first of all, all data and operations are carried out on the server side, and the client only displays its changed images, so there is no need to worry about the client illegally stealing data. The situation that we saw in the movie that the business spy copied the company's business secrets crazily with a USB flash drive will never happen again. Secondly, IT departments make various new rules according to security challenges, and these new rules can quickly act on every desktop.
Application scenario: system operation and maintenance of telecom business hall and IT industry.
Second, desktop virtualization, which virtualizes the computer terminal system (also known as desktop) to realize the security and flexibility of desktop use. We can access our personal desktop system anytime, anywhere through any device through the network.
Desktop virtualization depends on server virtualization. Server virtualization is carried out on servers in data centers, and a large number of independent desktop operating systems (virtual machines or virtual desktops) are generated according to proprietary virtual desktop protocols and sent to terminal devices. When the user terminal logs in to the virtual host through Ethernet, it only needs to remember the user name, password and gateway information, and it can access its own desktop system anytime and anywhere through the network, thus realizing multi-user on a single machine.
Why virtualize your desktop?
Users can access the desktop system remotely and get the same experience as a PC. Administrators can easily complete all the management work in the data center. Therefore, desktop virtualization technology effectively separates user use from system management.
End-user access to the desktop need not be limited to a specific device, a specific location and a specific time. We can access our desktop through any device that meets the access requirements.
trait
1, rapid and flexible deployment: on-demand application, rapid distribution, unified access without carrying heavy PC host, anytime and anywhere access;
2. Improve resource utilization: manage the resources of the back-end data center in a unified way, conduct unified scheduling management, and maximize resource utilization;
3. Safe and reliable data storage: The data is stored in the background data center, which is safe and reliable. And when visiting the virtual desktop, all the information transmitted on the network is picture information, which is not easy for others to steal information through the network;
4, convenient maintenance: the thin terminal does not need software maintenance; Virtual desktop maintenance can be unified in the background, which is very convenient;
5. Energy saving and emission reduction: With the desktop virtualization system, due to the low power consumption of the thin terminal and the high utilization rate of data center resources, it can save costs, save energy and emission reduction, and save electricity by more than 90%.
Application scenarios: big data server management, enterprise notebook management, telecommuting one-to-many branches.
