IDV or VDI, which is better for desktop virtualization?

IDV and VDI are both technical architectures to realize desktop virtualization, in addition to the mainstream VOI, the three have their own advantages and disadvantages, suitable for different application scenarios, there is no absolute superiority or inferiority, IDV can help the original business system to the new platform smooth migration, but it is only for the new hardware on the old operating system single scenario; VDI can meet the needs of mobile office, but it has high requirements for servers and networks, and poor compatibility of peripherals. VOI can efficiently manage legacy terminals and complex external devices, but it cannot solve the needs of mobility. The next-generation cloud desktop, which integrates the three-V architecture, is user-friendly, and can distribute VDI, VOI, and IDV based on the same architecture, covering a variety of application scenarios.

The differences between VOI desktop virtualization and VDI are as follows: different modes, different server clusters, and different configurations.

First, the mode is different.

1. VOI desktop virtualization: VOI desktop virtualization adopts a centralized management and decentralized computing model.

2. VDI: VDI adopts a mode of centralized management and centralized computing.

Second, the server clusters are different.

1. VOI desktop virtualization: VOI desktop virtualization cannot achieve high availability, hot migration, and large-scale deployment of server clusters.

2. VDI: VDI can be used for high availability, hot migration, and batch large-scale deployment of existing server clusters.

Third, the use is different.

1. VOI desktop virtualization: When the server fails or is disconnected, the VOI desktop virtualization terminal can continue to be used.

2. VDI: When the server fails or is disconnected, the VDI terminal cannot continue to be used.

First, the subject is different.

1. Desktop virtualization: virtualize the terminal system of the computer (also known as the desktop) to achieve the security and flexibility of desktop use.

2. VDI: It is an ideal choice. Virtual desktop infrastructure abstracts operating systems based on the number of users.

Second, the characteristics are different.

1. Desktop virtualization: Brings excellent responsiveness and customized user experience to intelligent distributed computing, and provides management and security benefits through a server-based model. Provides centralized management of the entire desktop image.

2. VDI: The operating system can be abstracted according to the number of users, and VGCS uses the destroy-on-logout (DOL) mode to ensure that the new virtual desktop infrastructure operating system can be used when logging in every day.

Third, the use is different.

1. Desktop virtualization: In the environment of very small WAN bandwidth, for example, under the line of less than 500KBS, VDiware and other VDI products can be used for deployment, and users can use tablet computers or mobile phones to access, access their own desktop environment, and realize office anytime and anywhere.

2. VDI: Client applications may not be suitable for all mobile platforms, which is related to the virtual desktop infrastructure software used.

Virtual Desktop Infrastructure (VDI) and Virtual OS Infrastructure (VOI) are the two mainstream architectures for virtualization and cloud desktops. Among them, the VDI architecture has great advantages in compliance, availability, and data security, but it is difficult to fully use local hardware resources. The VOI architecture makes full use of front-end computing resources, but it is difficult to meet the access requirements of terminals such as mobile phones and tablets.

The main differences are as follows:

Disadvantages of traditional VDI virtualization:

2. Because the client bears a large computing burden, they do not need to work on the network all the time, they can calculate when they are offline, and then transmit data when they are connected to the Internet, which reduces the dependence on the network a lot.

3. The mode of not being limited to the application of thin clients also makes it very compatible with various hardware peripherals.

Benefits of the new VOI virtualization:

1. The VOI-based virtual terminal management system not only inherits the advantages of the client's virtual container, but also expands and innovates the concept of the virtual container.

2. Hexin virtual terminal management system can not only meet many complex application environments;

We know that in addition to the shared cloud desktops mentioned earlier, there is also a virtual cloud desktop, which is what we call desktop virtualization, and desktop virtualization can be divided into two implementation methods: VDI and IDV desktop virtualization. What is the difference between these two types of desktop virtualization?

The first choice is the difference in design concept, the design concept of VDI desktop virtualization is centralized computing and centralized control, that is, all data is concentrated on one or more servers, an IT personnel can control hundreds or thousands of virtual cloud desktops at the same time, and complex work such as publishing desktops is all completed by the server, we can control the peripheral interfaces and access rights used by the terminal on the server management platform, and solve the desktop problems of end users on the management side; The design concept of IDV virtualization is distributed computing centralized management, that is, virtual desktops make full use of the hardware resources of cloud terminals, and each cloud terminal is a virtual desktop node, and the desktop system can theoretically be infinitely expanded.

The second is the hardware requirements, VDI desktop virtualization adopts the design concept of data centralization, so the hardware configuration requirements of the server that require the management of virtual cloud desktops will be relatively high, including CPU, memory, hard disk, etc., all of which require high configurations to drive more virtual desktop users to use; IDV desktop virtualization makes full use of the hardware resources of cloud terminals for data storage and computing, and the hardware requirements for cloud terminals are relatively high, but the requirements for server configuration are not too strong.

The third is the security of data, VDI desktop virtualization data is stored on the server or storage, the cloud terminal does not save data, and the security of data does not land, while IDV virtualization uses the hardware of the cloud terminal for computing and storage, and the security of the data is relatively low.

Fourth, the difference in flexibility, VDI desktop virtualization can support mobile office, no matter how you can go with people on the desktop, you don't necessarily have to use your own desktop files in your own office seat, and at the same time, in addition to supporting the use of cloud terminals, you can also support terminal equipment such as PCs, tablets, mobile phones, notebooks, etc.; However, how to virtualize IDV is highly dependent on the terminal, and its own desktop system is usually bound to the terminal, and it cannot access the desktop system anytime and anywhere like VDI.

Fifth, whether it supports offline office, VDI desktop virtualization, all computing is done through the server, which means that once the server fails or the network is disconnected, the cloud terminal cannot call the resources on the server and cannot work normally; IDV desktop virtualization is different, it mainly calls cloud terminals and resources for storage and computing, and when the server fails, the terminal can still work offline.

Whether it is VDI desktop virtualization or IDV desktop virtualization, they have their own advantages and disadvantages, and to say which one is better or more inclined to whom, it can only be said that the experience effect brought by using these two types of desktop virtualization in different use scenarios and applications is completely different.

VDI stands for desktop virtualization and IDV stands for interface device virtualization, and the two are completely different concepts.

Cloud desktop refers to a computer solution that uses cloud terminal devices to run remote server desktops over the network. Unlike traditional PCs, all data computing and storage on cloud desktops are centralized on remote servers, and cloud terminals only display desktop images and are responsible for the input and output operations of peripherals such as keyboards and mice. Features of Cloud Desktop:

Server - centralized operation, centralized management; Cloud terminal - does not run software and does not store data.

Let's drink soup and learn at the same time.

Virtual Desktop Infrastucture (VDI) is commonly known as virtual cloud desktop. First of all, put an iron frame (install the hypervisor) in the large clay pot (server), then put N small clay pots (virtualized into n different virtual machines), and then add different flavors of soup stock for high temperature simmering (install operating systems and software with different needs). Everyone can enjoy the soup with their favorite flavor.

VDI Virtual Cloud Desktop Architecture Diagram).

The friends don't have to make soup by themselves (the client doesn't run software and doesn't store data), and all the work is centralized to the chef and the big clay pot (the server runs centrally and manages centrally).

Suitable for: large enterprises that are particular about taste.

Conclusion: VDI belongs to cloud desktops.

Intelligent Desktop Virtualization (IDV) This is the "cloud desktop" proposed by the CPU boss Intel in order to save the PC market, which means that the original PC can also be transformed into a "cloud desktop".

The soup shop at the entrance of the village has prepared various flavors of soup in advance (virtual multiple different operating systems on the server), and friends can directly take their favorite soup home and reheat it to eat (install the hypervisor on the client, and then load the virtual machine on the server to the client for local use according to actual needs). Finally, IDV also uses mirroring technology to synchronize the data of each client to the server.

IDV architecture).

Everybody has to take the soup home and get their hands dirty (the client installs the hypervisor, loads the virtual machine and runs it locally. The client can run software and store data locally). In addition to managing clients, the server also plays the role of centralizing the data.

Suitable for: None.

Basically, no one wants to take takeout home and reheat it, right?! ）

Conclusion: IDV does not belong to cloud desktops.

To determine whether the client desktop belongs to the cloud desktop, we only need to check whether the system running on the client desktop is on the server.

VDI stands for Centralized ComputingAll desktop running systems are centralized on servers and belong to cloud desktops.

IDV stands for Distributed Computing on the ClientThe running system of each desktop is distributed among each client and does not belong to the cloud desktop.

The above content is excerpted from the popular science article "Distinguishing RDS, VDI, IDV, and VOI" from vCloudPoint Cloud Desktop

IDVs are often referred to as thick clients, as opposed to VDI (thin clients).

IDV has the following three characteristics:

1) Centralized management and local execution to minimize the amount of new data center builds, while using the processing power of smart clients to optimize the user experience. Even for server-hosted VDI, local execution with multiple redirects provides a better user experience, increasing VM density on the server. Higher levels of local execution provide better performance and lower costs.

2) Intelligently deliver layer images to improve update and patch operations, simplify storage, and avoid image drift. When IT divides desktop images into logical layers, each layer can be managed independently and the number of images can be minimized. Smart Transfer requires that the local image running on the PC be synchronized with the ** image.

This ensures that the image is always available to end users and IT staff. The synchronization and storage of these images should be enhanced with deduplication techniques to minimize storage and network bandwidth requirements.

3) Use out-of-band mode to access devices, providing OS-independent management and enhanced security.

Now that VDI has become very popular, many companies are doing it, and the market is more optimistic about IDV in the future.

IDV has a miniature virtualized system between the hardware platforms, and then installs the operating system on the virtualized system, that is, the system is isolated from the hardware, and all addressing must be mapped and ** internally. The biggest advantage of this is to achieve the unified standardization of the hardware platform, no matter what period of time the PC is purchased, you can unify the image management, without considering the problem of hardware compatibility, for example, some people have been asking recently that the CPU after Intel 6 generation can not support Win7 is solved by IDV, because no matter how new the hardware (Intel 7, 8, 9 and other latest CPUs) is in the running virtual machine environment, not afraid of incompatibility.

In fact, the choice of cloud desktop with technical architecture depends on the user's usage scenario. According to the user's existing terminal, server, network environment, and business content, combined with the user's budget to formulate a feasible solution, which can better meet the actual needs of the user. According to the increasingly refined and diversified needs of users, general-purpose cloud desktops represented by next-generation cloud desktops with integrated three-V architecture have become an important trend, so that procurement costs can be better controlled, and only one cloud desktop can meet different industry application scenarios.
