Virtual Office system based on cloud technology

With the increasing reliance of enterprise development on information technology, information system has become an important tool of enterprise management.

Set desktop Office, application, data three elements in one of the Virtual Desktop Office system, can be paired with the appropriate client, all data and applications are concentrated in the data center of the server, the effective implementation of data, applications and client separation, greatly enhance system security, manageability and usability.

Use of Office systems

Enterprise's application information system is the face of different employees, the role of the formulation, the general staff can only be in accordance with the responsibilities of the job to enjoy a user module rights. If the employee a in the enterprise position is the material department leader, he passes through the password identity authentication to enter the system, only then sees oneself role authority information. If, in an emergency situation, he needs to work on other PCs in the system, he is eager to be able to log on to his desktop offsite without reconfiguring, which is hard to achieve in old PC management mode.

In addition, because of the wide range of PC hardware, different departments, different systems on the desktop environment, hardware configuration is not the same. Therefore, the PC desktop standardization becomes a problem. The distributed characteristics of PC make it difficult for enterprises to concentrate resources, improve utilization rate and reduce cost.

Enterprises in day-to-day PC management, hardware maintenance, software deployment, updates and patches, such as the cost of a large human and material resources. In order to solve the above problems, the introduction of virtual Office system has become a new breakthrough.

Cloud Computing and virtualization technology

Cloud computing (cloud computing) is a kind of distributed computing technology, its most basic concept is through the network to automatically split the huge computing process into countless smaller subroutines, and then to a large number of servers composed of a huge system, after the search, calculation and analysis of the processing results back to the user. Through this technology, Web service providers can handle tens of millions of billions of dollars of information in a matter of seconds.

Virtualization is a broad term in the computer field, usually refers to the computational components on the virtual basis rather than on the real basis of the operation. Virtualization technology can expand the hardware capacity and simplify the reconfiguration process of the software. The virtualization technology of CPU can enable single CPU to simulate multiple CPUs parallel, allow a platform to run multiple operating systems simultaneously, and the application can operate in each other's independent space without affecting each other, thereby significantly improve the efficiency of the computer.

The conception of Virtual Office system

The whole architecture of virtual Office system is divided into 3 layers, namely virtual storage layer (storage pool layer), server cluster layer (CPU, memory resource pool layer), management and Application layer. The whole virtual storage system can be considered as a whole, and the server cluster is built on the basis of shared storage system.

The system automatically detects failures while using fewer redundant components. The Virtual Office system utilizes the virtual storage layer and the server cluster layer to provide the hardware resource pool, establishes the virtual machine resource, builds the 3rd layer (the management and the application layer) on the basis of the virtual machine resources, and has the management function such as management service and user authentication.

Through a series of virtual office technology applications, Office data from the previous scattered storage transferred to the more secure All-weather computer room environment centralized storage, and the professional and technical personnel to manage the unified.

This kind of management method first makes the traditional data security to be effectively promoted;

Secondly, it realizes the absolute control of the data, achieves the terminal data stream access, and fully guarantees that the information and data are not leaked;

Once again realize the unified management of the operating system, so that the system maintenance personnel do not have to shuttle in all the scattered office locations, through telephone communication can be centralized maintenance of the software system, if the user application system initialization, with a preset template, in just a few minutes can redeploy the application system;

Finally, on the basis of virtualization technology, the system can divide the resources more granular, further improve the utilization of hardware resources, and effectively save costs.

The desktop virtualization market will grow rapidly from now to 2013, according to a global technology research and consultancy Gartner Report, and by 2014, around 15% of the world's traditional PCs will be transferred to virtual desktops.

Today, some large enterprises have begun to explore the cloud characteristics of the office, with the continuous upgrading of technology, virtual Office system function and performance will be further improved, and eventually form a mature, high-quality, efficient "desktop cloud."
