What are the benefits of desktop virtualization? What is a virtual desktop? What s the use

1. Integration of resources to complete the integration of resources is the main work of server virtualization, in the information age, all walks of life in the development process, the data generated is the most advanced growth, how to achieve the comprehensive utilization of these data and resources, is the problem that major industries need to solve. The R&D and application of computer server virtualization technology provide technical support and application platform for resource integration. Especially in recent years, the continuous popularization of cloud computing technology, centralized resource management is more and more advanced, providing conditions for the development and promotion of cloud technology, the utilization rate of computer hardware resources of major enterprises is less than 20%, and the waste of resources is still very serious, through server virtualization technology can be maintained on the basis of the original application, concentrated in a computer server, which can promote the utilization rate of material resources of enterprises to be greatly improved, thereby reducing the investment of various hardware and saving costs.

2. Low energy consumption In the information age, the top priority of technological innovation is also the main way to reduce resource consumption. Computer server virtualization is the main way to improve resource utilization, and it can also reasonably manage energy consumption. Virtualization technology can simulate different scenarios, so as to achieve a comprehensive and systematic inspection of various hardware and software in the computer system, and immediately display problems on the interface to remind relevant personnel to deal with them in time, so as to reduce energy consumption and achieve the purpose of green development.

3. Reduce operating costsIn the context of the continuous business transformation of information service providers, intensification has put forward higher requirements for cost control, and investment has become more and more refined. Investments supported by computer hardware and licensing services. The cost investment of computer system operation and maintenance can give full play to the performance of the server through computer server virtualization technology.

4.

More than 10 years of professional field, dedication.

One communication, a lifetime of companionship.

1. More flexible access and use: users can remotely access the desktop system and get a completely consistent experience with the PC;

Administrators can also easily complete all the management work just by being in the data center; Therefore, desktop virtualization technology is essentially an effective separation between user use and system management. 2. Broader and simplified terminal device support: we can use a variety of devices, thin clients, mobile phones, TVs, keyboards, mice or other peripheral scanners to access desktops or applications like watching TV and selecting stations; 3. The cost of terminal equipment procurement and maintenance is greatly reduced, which indirectly reduces the amount of electronic waste generated 4. Centralized management, unified configuration, and safe use

All data and computing occur in the server-side data center, so confidential data and information do not need to be transmitted through the network, which increases security, and these data can also be configured not to be allowed to the client to ensure that users will not take away and spread confidential information. 5. Reduce power consumption, energy conservation and emission reduction.

The high energy consumption of the PC is usually 200W, while the low energy consumption of the terminal device is only 5W, which saves energy.

Virtual desktop refers to the virtualization of a computer's terminal system (also known as a desktop) to achieve the security and flexibility of desktop use. Our personal desktop system can be accessed from any device, anywhere, and at any time via the Internet.

Virtual desktops rely on server virtualization, which is performed on servers in the data center to generate a large number of independent desktop operating systems (virtual machines or virtual desktops), and at the same time send them to terminal devices according to the proprietary virtual desktop protocol. The user terminal logs in to the virtual host through Ethernet, and only needs to remember the user name and password and gateway information, and can access their desktop system through the network anytime and anywhere, so as to realize single-machine multi-user, Tianyuan Tengchuang friendly answer.

For example, if an enterprise builds a new data center, hundreds or even thousands of terminals adopt the traditional model, and it will take at least a few weeks to complete the deployment from operating system to application software, installation and commissioning of business systems, network, and storage. However, if cloud desktops are used, especially when the hyper-converged cloud desktop solution is used, this delivery time can be shortened to a few days or even hours. Based on virtualization technology, the standard image template is completed in a unified manner on the backend, and the frontend can be turned on.

In terms of operation and maintenance, cloud desktops are easy to manage and maintain, ending the downtime caused by software system failures, and even if the terminal hardware is damaged, it only takes a few minutes to put into work with a new device, while it takes one working day to install the system and software before a new machine is put into operation.

The principle of application virtualization technology is based on the application server computing ASS architecture, which adopts technology similar to virtual terminals to isolate the human-computer interaction logic of the application (application interface, keyboard and mouse operation, audio input and output, card reader, printout, etc.) from the computing logic. When the user accesses an application after server virtualization, the user's computer only needs to transmit the human-computer interaction logic to the server, and the server opens an independent session space for the user, and the computing logic of the application runs in this session space, and the changed human-computer interaction logic is transmitted to the client, and displayed on the corresponding device of the client, so that the user can get the same access experience as running a local application.

Desktop virtualization remotely accesses desktops on a server through the UXP or RDP remote desktop protocol, while application virtualization decouples applications from the operating system to provide a virtual runtime environment for applications. In this environment, not only the executable file of the application is included, but also the runtime environment that it requires. In essence, application virtualization is to abstract the dependence of applications on low-level systems and hardware, which can solve the problem of version incompatibility.

The benefits of desktop virtualization to IT departments are as follows:

Reduce the number of servers, provide a method of server consolidation, reduce the initial hardware procurement cost, simplify the deployment, management and maintenance of servers, reduce management costs, improve the utilization rate of server resources, improve server computing power, reduce data center costs by reducing space, heat dissipation and power consumption, etc. The highly reliable server application environment is automatically reconstructed by the system, which reduces the downtime of the server or application system, supports the integration of heterogeneous operating systems, supports the continuous operation of old applications, and updates the system without interrupting the work of users.

Enables rapid transfer and replication of virtual servers, providing a simple and convenient disaster recovery solution.

1. Integrate servers.

Significant savings in power and cooling costs can be achieved by reducing the number of physical servers by turning them into virtual servers. In addition, it can also reduce the cost of data center UPS and network equipment, the space occupied, and so on.

2. Avoid excessive deployment.

Before implementing server virtualization, administrators often need to deploy additional servers to meet unexpected needs. With server virtualization, this additional deployment effort can be avoided and it supports perfect segmentation of virtual machines.

3. Do more with less.

In a downturn, IT departments and administrators need an ideal way to do more with less. Server virtualization can help administrators achieve IT management more flexibly and efficiently.

4. Save money.

With server virtualization, companies can not only enjoy the cost savings of physical servers, power supplies, and cooling systems, but also dramatically reduce valuable time managing physical servers. End-users will also be more loyal due to efficient and stable operation.

5. Migrate virtual machines.

One of the great features of server virtualization is the ability to migrate running virtual machines from one host to another without downtime. VMware's vMotion does just that, making it possible to do things like Distributed Resource Scheduling (DRS) and Distributed Power Management (DPM).

6. Reduce downtime events.

Similar to vMotion, Storage vMotion (SVMomotion), DRS, and VMWare High Availability (VMHA) all help virtualized servers run longer than physical servers.

7. Image-based backup and restoration.

Virtual machines can be backed up and restored, and fast backup and restore can be achieved. In addition, image-level backups make disaster recovery easier. What's more, advanced technology can be leveraged for differentiated backup.

8. Virtual laboratory.

Virtual servers allow you to create virtual labs (a set of virtual machines on a virtual private network) that allow you to test vSphere, Exchange, Active Directory, and other applications. In the past, this was unattainable (and expensive) for physical servers.

9. Simplify disaster recovery.

Virtualization makes it possible to restore mirrored backup files on hardware running vSphere without relying on a specific physical server. In addition, in the event of an outage, the Site Recovery Management Tool (SRM) can be used for automated testing and failover.

10. It is easy to migrate to the "cloud" side.

By virtualizing the servers, we were able to move them to a cloud service company.

Computer virtualization technologies currently include server virtualization, application virtualization, and desktop virtualization. At present, network virtualization, graphics card virtualization and other technologies are developing rapidly, and in the near future, the current physical equipment will support virtualization technology, implement IaaS (Infrastructure as Service), and implement cloud computing in the real sense. Desktop virtualization technology is currently the fastest growing and most promising technology.

Desktop virtualization refers to the virtualization of computer desktops to achieve security and flexibility in desktop adoption.

Similar to service outages, application flow or application virtualization supports centralized application management without impacting responsiveness or performance. Data can be stored locally or centrally, depending on corporate policies. In addition, streaming applications can be cached for offline use, making it a centralized management model that supports mobile computing.

Because the data is on the client during the execution of this pattern, this mode is not suitable for applications that require high data security.
