Does your remote desktop, Citrix, or ERP solution run so slowly you want cry?
Desktop virtualization is software that separates the desktop and associated applications from the physical device that runs them. Remote desktop virtualization operates in a client/server environment. Applications are executed on a remote operating system linked over a network to the local client device with only display, keyboard, and mouse information transmitted between devices. All applications and data remain on the remote system. Users interact with the server and applications via conventional PC/laptop, a thin client device, a tablet, or even a smartphone.
Desktop virtualization can be used in conjunction with application virtualization and Windows user profile management systems to provide a comprehensive desktop environment management system. With this approach, all the components of the desktop are virtualized, creating a highly flexible and secure desktop delivery model. In addition, desktop virtualization offers a more complete desktop disaster recovery strategy because all components are in the data center where they can be regularly backed up. Because no data is saved on the user’s device, there is much less chance that any critical data would be compromised if a device running desktop virtualization were lost.
Remote desktop virtualization is frequently used in the following scenarios:
- Distributed environments with high availability requirements and where local technical support is not readily available.
- Environments where conventional client/server applications run slowly due to high network latency.
- Environments where security considerations dictate that all application data reside within the data center.
It is also used as a means of providing access to Windows applications on non-Windows endpoints including tablets, smartphones, and non-Windows-based desktop PCs and laptops. Remote desktop virtualization can also lower costs in environments where providing every user with a dedicated desktop PC is too expensive.
Virtual Desktop Infrastructure
A Virtual Desktop Infrastructure (VDI) is a desktop-oriented service that hosts user desktop environments on remote servers. Users access their desktops over a network using a remote display protocol. A connection management service links users to their assigned desktop sessions running on the remote servers. VDI enables users to access their desktop from any location without having to use a specific client device. Since the resources are centralized, users moving between work locations access the same desktop environment featuring their applications and data. From a support perspective, VDI delivers a more centralized, efficient client environment that is easier to maintain.
Citrix is the leading provider of VDI solutions with their Xen suite of products.
Remote Desktop Services
Remote Desktop Services (also called Terminal Services, server based computing, and presentation virtualization) is a component of Microsoft Windows that delivers access to applications and data on a remote computer over a network using a remote display protocol. Remote Desktop Services is similar to VDI in many respects. It, however, differs from VDI in two important ways.
- VDI service provides individual desktop operating system instances for each user. Remote Desktop Services sessions run in a single shared Windows server operating system.
- VDI is designed to deliver full desktop environments. Remote Desktop Services can provide connections to either individual applications or full desktops as needed.
Remote Desktop consumes significantly fewer resources than VDI because Remote Desktop uses a single shared server operating system for all users rather than individual desktop operating system instances for each VDI session. VDI implementations, however, allow for personalized workspaces for each user.
However, VDI can encounter challenges when deployed over wide area networks (WAN). Any time you separate end users from their data, especially over great distances, performance can suffer. In many WAN applications, optimization technology is required to deliver the level of performance users demand.
Benefits of the AS Cloud-Based Acceleration Service
Acceleration Systems’ unique cloud-based WAN optimization service improves the performance of all applications accessed through VDI applications, especially critical office applications such as MS Word, Excel, and PowerPoint, as well as Internet, intranet and enterprise websites traffic.
As a result, Acceleration Systems delivers Citrix XenDesktop and Microsoft Remote Desktop Services users key benefits:
- Provides a higher-quality user experience over WAN connections by delivering virtual desktop applications up to 70 percent faster.
- Lowers costs of virtual desktop projects by supporting up to twice as many virtual desktop users on the same WAN link by reducing WAN traffic up to 60 percent.
- Dramatically improves remote printing by greatly reducing the volume of data required to transfer print files to remote sites.
Acceleration Systems employs a combination of optimization techniques which double the number of users that a given link supports while providing uniform, scalable performance for all users.
Remote print jobs, a challenge in any computing environment, execute much faster as a result of techniques which accelerate centralized printing through print-specific optimizations, block level deduplication, in-stream compression, multiple caching strategies, and TCP Optimization.
