Desktop virtualization
Virtual Desktop Infrastructure refers to a data center infrastructure in companies that are virtualized with the full desktop PCs.
Background
Desktop virtualization in the enterprise is the logical development of server and storage virtualization. It will complete the PC desktop is virtualized in the data center instead of a single component or application.
The PC has revolutionized business, so that a work is unimaginable without him. The productivity that results from the use of traditional PCs, requires significant investment. Many of these costs are well documented over the years, while many of the hidden costs occurred only in recent years come to light. Expensive hardware replacement cycles are nothing new just as comprehensive help desk and numerous IT staff to maintain the IT operations.
Elaborate on the other hand costs must be quantified concerning security and compliance requirements of desktops and laptops. The same applies to sensitive data stored locally on the computers of employees. The time and money that are spend to buy a standard PC to configure and install, see the competitive and fast moving global markets of today more and more attention.
Virtual Desktop Solutions
Based on virtualization solutions AppliDis Fusion 4, VMware, Citrix, Xen, Sun Microsystems, Univention, Wyse, or Microsoft Enterprise desktops are distributed to multiple server-based virtual machines.
The virtualization software can be connected with the well-known by the server based computing thin client to a powerful and cost-effective computing infrastructure. This solution, which is denoted by the manufacturers with different names - Enterprise Desktop Virtualisation (EDP ) Wyse Virtual Desktop Infrastructure ( VDI) VMware -, each client allows you to assign a dedicated virtual machine on a server.
Although the concept of desktop virtualization is relatively new compared to server virtualization, the demand is high. Especially large companies with complex requirements, such as in financial or accounting departments, have an increased need for cost-effective technologies to provide the required desktop environment to their employees. To meet the increasing demand for virtual and dynamic IT infrastructures, more and more companies develop appropriate solutions. With the solutions, companies can not only make the virtualization of individual applications, but equally affect the entire user desktop - including all applications and personal settings.
As with the server based computing, users can put in a virtual desktop solution basically use the same standard PC. A major advantage of VDI is that the operating system runs independently for each workstation in its own dedicated virtual machine. In this way, the applications of two users can not influence each other. In addition, a consolidated data center virtualized desktop infrastructure means that companies secure, isolated desktops can provide that will be available without interruption. And each thin client is centrally organized and accessible from anywhere on the network.
The distribution of remote access for users to the correct virtual machines can be coordinated by using a so-called connection broker.
General modes of
To better understand customers take advantage virtual desktop infrastructures for enterprises and how they support the provision of end-user desktops, without meeting the hardware limitations of the local PC, you should take a look at the basic network installations. A key role of the server on which the virtual machines of the individual desktops are hosted. On the x86-based hardware, the virtual infrastructure software is typically installed.
The size and speed of this server generally depend on how many clients are connected, as is the expected network traffic (including I / O traffic called ) is and how much load or " Workload " occur. For example, would a suitable midrange server with four dual -core processors and 32 GB of RAM for a company with up to 65 connected thin-client workstations. An affordable network storage system (NAS ) for applications and files added to the configuration.
In infrastructure with several hundred clients with desktops it is to virtualize, however, is a storage attached network or SAN solution on a shared storage pool as a "best practice" regarded by IT professionals, since the aspects of performance, high availability and better scalability is supported in the rapidly growing volumes of data according to Bill.
Central Idea: With virtual infrastructure solutions of the approach is that companies simplify their IT and optimize the investment in IT systems. It should thus be possible to respond more quickly and flexibly to business needs. Through a flexible IT infrastructure staff productivity as well as their service levels should be increased.
