What is Application Virtualization? What is the application virtualization software?

The benefits of application virtualization are mainly on-demand, and users can use these applications directly on their mobile phones or tablets through authorized clients=. Domestic application virtualization office will be a trend, you can try Sailan 8-hour mobile cloud ICAB, which can save a lot of enterprise costs, but also convenient for mobile office, there are several domestic application virtualization software brands, which can be searched.

Mobile virtualization in China: telecommunications.

Unicom. Mobile is being done in conjunction with other manufacturers.

You can also consult them to provide you with relevant mobile virtualization solutions.

There are three main types of server virtualization.

citrix

xenserver

Microsoft. windows

server

hyper-v

vmware

esxserver

This is the most commonly used.

General features: abstract the physical resources of the server into logical resources, so that a server becomes several or even hundreds of virtual servers isolated from each other, or let several servers become a server to use, we are no longer limited by physical boundaries, but let CPU, memory, disk, IO and other hardware become a "resource pool" that can be dynamically managed, so as to improve the utilization of resources, simplify system management, realize server integration, and make IT more adaptable to business changes.

server

Running on bare metal servers, it is a hardware-based architecture. It is an enterprise-level application. The underlying hardware of the same server is used to divide several virtual machines into centralized management, which is convenient for clustering, load balancing, hot migration and other functions.

XenCenter is Citrix's virtualization graphical interface management tool that allows you to manage multiple XenServer servers from the same interface. In terms of management, it is common to first set up a server group (pool) in XenCenter, and then join the XenServer servers located in the same data center.

As with most server paravirtualization products, when several XenServer servers are connected to the same shared disk drive, and the virtual file is placed there, the Xen-Motion feature can be used to manually transfer virtual machines to other XenServer servers for host maintenance or to reduce the consumption of hardware resources.

I knew about it from outside the IT number.

Application virtualization consists of two main aspects: shared desktops and remote applications.

Share your desktop. A complete desktop based on Windows RDS (Remote Desktop Services) is more lightweight than ordinary virtual desktops, with session isolation between users, user profile roaming data stored on a shared file server, and a shared storage system is used to store data, and the file system and storage system are provided by a third party.

Remote applications. Based on the RDS service of Windows to publish applications, centralized control and management of applications, provide remote application services to users at any time and anywhere, end users can use applications without installing applications, user profile roaming data is stored on shared file servers, storage data uses shared storage systems, and file systems and storage systems are provided by third parties.

User Data Storage.

Profile roaming of shared desktops and remote applications for individual users: Use the Roaming User Configuration and Folder Redirection functions to provide profile data roaming and store them on shared file servers provided by third parties.

Support shared desktop, remote application personal user data storage: User personal data is stored using a shared storage system, and the storage system is provided by a third party (such as NAS).

Software Compatibility.

Deployment Application Software Requirements:

The software must support multi-instance operation and be able to open multiple program instances at the same time.

Software that requires administrator privileges to run is not supported.

Virtualized computing elements operate on a virtual basis rather than a real one, and are a solution designed to simplify management and optimize resources. Just like an empty and transparent office building, there are no fixed walls on the entire floor, and users can build a more autonomous and applicable office space at the same cost, thereby saving costs and maximizing the utilization of space.

1. CPU virtualization.

Virtualization, on the computer side, usually refers to computing elements running on a virtual basis rather than a real one. Virtualization technology can expand the capacity of hardware and simplify the process of reconfiguring software. To put it simply, CPU virtualization technology is a single CPU that simulates multiple CPUs in parallel, allowing a platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thereby significantly improving the efficiency of the computer.

2. Network virtualization.

Network virtualization is currently the most unclear and controversial concept in the industry. In Microsoft's eyes, "network virtualization" refers to virtual private networks (VPNs). VPNs abstract away the concept of network connectivity, allowing remote users to access an organization's internal network as if they were physically connected to that network.

Network virtualization can help protect the IT environment from threats from the Internet, while enabling users to quickly and securely access applications and data.

3. Server virtualization.

Different from network virtualization, server virtualization is the earliest sub-field of virtualization technology. According to a February 2006 ForresterResearch survey, 75 percent of enterprises worldwide are aware of server virtualization. One-third of enterprises are already using or preparing to deploy server virtualization.

This technology, which was born in the 60s of the 20th century, is increasingly showing its importance. Due to the long development time and wide range of applications of server virtualization, many times people almost equate server virtualization with virtualization.

4. Storage virtualization.

With the continuous operation and development of information business, the storage system network platform has become a core platform, a large number of high-value data has been accumulated, and the application of these data has higher and higher requirements for the platform, not only in terms of storage capacity, but also in terms of data access performance, data transmission performance, data management capabilities, storage expansion capabilities, and so on. It can be said that the comprehensive performance of the storage network platform will directly affect the normal operation of the entire system. For this reason, another subfield of virtualization technology, virtual storage technology, came into being.

5. Application virtualization.

With the increasing application of IT, application virtualization has entered the historical stage as the rising star of the virtualization family. According to a July 2006 U.S. study of senior IT executives in a variety of industries conducted by Forrester Consulting, today's organizations now view application virtualization as a business necessity rather than an IT decision. According to statistics, at least 180,000 organizations around the world are using virtualization technology to centralize IT management, strengthen security and reduce overall costs.

Virtualization can speed up the deployment of new servers and applications, dramatically reducing server rebuild and application load times. Proactively plan for resource growth in advance so that you can respond quickly to customer and application needs, rather than the lengthy procurement process that used to take place and then try it out.

In the process of computer server virtualization, equipment and IO are also the main components of the computer system, and virtualization is also needed to promote the virtualization of the server. Compared with memory virtualization, device, IO, and network port virtualization is mainly implemented through professional packaging technology to provide technical support for the operation of virtual machines. It often meets the needs of virtual machines for device access and IO requests, and lays a solid foundation for the virtualization of devices and IO in the computer server virtualization platform.

In the specific operation, there are certain differences in the computer server in the computer server in the model, configuration, parameters, etc., but the specific realization of the computer server, the exchange of data and information between the virtual machine and the physical machine, showing the effect of the application of server virtualization technology. The rational application of this technology can not only expand the application scope of computer server virtualization technology, but also greatly reduce the dependence on the underlying hardware of the computer in the information age. As long as a virtual platform is built, it can be migrated to different physical machines.

More than 10 years of professional field, dedication.

One communication, a lifetime of companionship.

In practice, virtual machines and some game simulators are used; For example, various mobile game simulators, win arcade game simulations and so on.

And a very small number of games can be turned on virtualization to improve the smoothness of the game, but it is basically not used in daily use.

1.Virtualization technology belongs to cloud computing technology.

On the whole, the technology occupies a core dominant position and is obviously advanced. VR social, VR shopping, VR games, VR conferences, VR fitness, VR virtual meeting rooms, etc., the emergence of virtualization technology has well solved the dilemma of insufficient computer hardware resources, and with the continuous development and improvement of technology, virtualization technology is safe and reliable, and the characteristics of high utilization rate make the application level of the server further improved and the service effect has been improved. At present, virtualization technology is mainly divided into three aspects, namely complete virtualization, partial virtualization and operating system virtualization.

According to the differences in abstraction levels, virtual technology can be divided into five levels: hardware level, instruction level, programming language level, operating system level and runtime library level. There are differences in the five levels, but they are essentially the rational allocation of resources for the use of the upper layers.

The software is called "Wei Xiaolai" is developed on the basis of the metaverse, VR virtual conference room, not only can allow everyone to work remotely and efficiently with fun, through sharing the screen, **, files, but also screen drawing, multi-person voice sharing to discuss topics together. And you can also build cities, factories, etc. by self-study. Not only can you quickly build scenes, models, 3D renderings, but also can VR roaming, etc.

2.The status quo of the application of network security monitoring technology in the virtualization environment At this stage, the application of network security monitoring technology in the virtualization environment is widely accepted and valued, with the deepening of the degree of use, the amount of data information in the network continues to increase, the importance level continues to improve, along with the improvement of the functionality and convenience of the network system, there are also some system factors that can threaten the security of data and information. The traditional network security monitoring technology is slow to update, the adaptive ability is insufficient, and it is difficult to filter or defend against today's threat factors, so the network security monitoring technology is useless and cannot play a good role in security monitoring.

The application of network security monitoring technology in the virtualization environment solves the shortcomings of traditional network security monitoring technology, and the powerful information data analysis ability makes the network security monitoring technology in the virtualization environment adapt to users, so as to continuously improve the filtering and defense level of network threats. When designing the application of network security monitoring technology in a virtualized environment, it is necessary to follow the principles of security and effectiveness to prevent the virtual manager from having vulnerabilities or being attacked by external sources. Specifically, the application of network security monitoring technology in a virtualized environment can be divided into two aspects: internal and external.

Among them, the internal monitoring is mainly for the abnormal situation of the kernel module, intercepting the abnormal events, and the virtual manager manages multiple virtual machines to load the kernel to ensure absolute network security. External monitoring places more emphasis on the rational use of virtual machines to improve the interception effect and detection efficiency of abnormal events.
