Citrix Desktop Virtualization Solution vs VMware Desktop Virtualization Solution

delivering virtual desktops for various scenarios through XenDesktop and Flexcast issues facing the Enterprise desktop

Providing each user with a secure and efficient desktop environment is a basic requirement for almost any company or organization. If users cannot use their desktops or applications, the company will not be able to operate efficiently. Every few years, almost every company or organization will be using a large number of new operating systems, new hardware or new applications, which requires a lot of people to build, test and publish the latest systems on a large scale. This vast and cumbersome process often delays many favorable upgrades to the enterprise, which may lead to the inability of enterprises to respond quickly to market demand.

While many vendors offer automated tools to help deploy new applications and operating systems, the problem is that the traditional approach (which will be deployed to a large number of end customers) is not the best approach. This traditional approach is likely to adversely affect users and businesses, such as:

• The important data of the enterprise located at the terminal are easily leaked through various channels;

• The loss of terminal user equipment caused by data loss and other major security risks;

• Damage to the operating system or applications due to malicious or unintentional behavior, requiring a large number of troubleshooting and repair time, resulting in end user downtime;

• Significant costs associated with new hardware purchases, resulting in delayed system upgrades.

In addition, for the maintenance of a large number of staff computers, the main challenges facing the following:

• Client operating systems, application clients need to constantly upgrade, and constantly patched

• Client antivirus, anti-malware task difficult, not to expect every user is an expert

• Client hardware needs to be upgraded every three years or so, with huge investment

• A lot of security products are deployed and the data is still easily leaked

To ensure that security has to sacrifice a lot of convenience, the system uses complex
Solution

Rather than the old-fashioned approach of deploying operating systems and applications to all terminal physical workstations, the new approach--citrix Virtual desktop solutions to provide users with a secure desktop design environment without the time and expense associated with large-scale publishing of desktops and securing data security.

A virtual desktop is a desktop operating system that is a virtual operating system running on a server. In Virtual desktop mode, everyone enjoys their own operating system. brings a number of benefits to virtualization of desktop operating systems, including:

• Information preservation in the data center to ensure the security of data;

• Desktop performance can be improved because it and the server at the back end of the application are running in the data center;

• Desktop can share the latest and most powerful server hardware;

• Remote access to the desktop from any location;

• The cost of maintaining the desktop is greatly reduced. For the above problems, we recommend using Citrix XenDesktop Virtual Desktop solutions to meet the above challenges. The Citrix XenDesktop Desktop Virtualization solution provides an end-to-end desktop management solution. Dynamic on-demand generation of virtual desktop, the desktop all the operation occurs in the remote Data center of the computer room, no longer worry about the data resides in the client-led security vulnerabilities. Users get a clean, personalized, new desktop every time they log on--ensuring that performance does not degrade.

The XenDesktop solution contains a number of components to provide the best solution for each enterprise's unique needs. Desktop Virtualization Complete solution overall architecture as shown.

The scheme will adopt the five core components of the architecture:

1. Virtualization infrastructure (virtualized infrastructure): A virtualized infrastructure allows a single physical server to be divided into virtual servers for multiple shared resources. The virtualization infrastructure of this scenario is the base

Built in XenServer or vsphere as part of a xendesktop overall solution.

2. Virtual Desktop Delivery Controller (Virtual Desktop delivery Controller): Desktop delivery Controller is responsible for registering new virtual desktops and pointing requests for virtual desktops to available systems. The user interacts indirectly with the controller through a consolidated Web interface component. Deliver a virtual desktop to a user through a Web site, or through a locally installed sink.

3. Virtual Desktop Provisioning (VM Provisioning): The provisioning server for XenDesktop Solutions provides operating system mirroring for Virtual desktop instances on a virtualized infrastructure. A basic operating system image is created that includes all operating system-level configurations defined by the enterprise policy. When each virtual desktop is started, the operating system is delivered to the virtual desktop via streaming technology over the network. Because only basic mirrors are required to be upgraded, and all virtual desktops will use the latest mirrors for the next reboot.

4. Application Delivery Controller (Application Delivery Controller): The application Delivery controller is responsible for identifying the application assigned to the user and delivering it to the virtual desktop. Application delivery is the first part of User desktop personalization based on user requirements. By separating the application from the basic desktop image, the number of desktop mirrors required is significantly reduced, which simplifies the maintenance process.

5. Personalization: The personalization of the solution allows users to customize their work environment as required. With user personalization, user settings are saved, and saved personalization can be used regardless of the user's access to the desktop. User personalization is not simply a roaming feature, because Citrix User Profile Manager removes all unnecessary settings and retains only the values that are valuable to the user. Also, personalization delivery is optimized so that users do not have to wait for a virtual desktop to load for a long time.

Programme Advantages

Using Citrix Desktop Delivery technology, users use an existing PC or a corresponding computing device, such as a small thin client with monitors and keyboards-a device commonly referred to as a virtual desktop device or VDI, where users install virtual desktops from the data center, which has many advantages over previous traditional desktop models:

1, security strengthening

• Virtual desktop operating system is placed in the data center, relative to the traditional PC, not vulnerable to malicious attacks.

• Security patches can be installed only on standard Windows images in the data center.

• When desktop hardware is replaced by other "thin devices," it can reduce the likelihood of users stealing information and importing computer viruses by prohibiting the use of removable storage devices such as USB.

• Information preservation in the data center to ensure the security of data;

2. Reduce the cost of operation and maintenance

• Focus your PC on the data center, or you can speed up the creation of a new desktop, usually by simply installing a file that contains the existing Virtual PC desktop.

• A Virtual PC needs a patch that can be quickly installed without having to access each work area.

• The cost of maintaining the desktop is greatly reduced.
