Citrix XenApp
Citrix XenApp™ (the new name of Presentation Server™) addresses many IT and business challenges by providing a strategic, end-to-end application delivery system. It delivers all Windows applications to all users and locations, securely and reliably, optimizing performance. It offers both client-side and server-side application virtualization to enable the best access experience for any user. By centralizing applications and data in secure datacenters, IT can reduce costs of management and support, increase data security, and facilitate business continuity and disaster recovery.
Here’s how Citrix XenApp can help your organization develop access solutions for today’s top challenges:
Remote Office Connectivity — Give users at remote branches, offices and other locations secure access quickly to all resources. Accelerate business integration after mergers and acquisitions, especially for distributed branch offices and workers with Citrix application delivery solutions.
Workforce Mobility — Deliver high-performing application access to mobile workers, over any network — wired and wireless, public and private, dedicated and dial-up. Citrix SmoothRoaming™ ensures continuous access, when users roam between devices, networks or locations—even across wireless dead zones.
Business Continuity — Keep business going during planned or unplanned outages. Enable workers to access business-critical systems from any remote location on any Web-enabled device. Perform application maintenance with no impact to end users. For multi-site deployments, transparently redirect users to alternate sites when regularly accessed sites are unavailable. Recover from disasters faster and easier through centralized application delivery, and eliminate time-consuming and costly desktop rebuilds.
Server Consolidation — Reduce total cost of ownership (TCO) and ease IT management by reducing datacenter infrastructure. Leverage new technologies like 64-bit computing platforms to significantly increase user density per server and application performance. Manage and control applications and the servers centrally, to reduce IT costs and increase productivity.
Regulatory Compliance — Comply with government and industry regulations faster while reducing associated costs. Increase access security, better control application delivery, maintenance, and upgrades, centralize monitoring and reporting, increase IT productivity and reduce auditing time and costs.
Business Process Outsourcing — Quickly enable secure and less-costly outsourcing of business processes. Maintain applications and data in your datacenter while providing secure remote access to outsourcing service providers, supporting regulatory compliance. Enable service providers to use any local devices to reduce their expenses and speed the integration.
Application Streaming
The application streaming technology in XenApp, extends IT’s ability to manage and deliver Windows-based applications centrally to any user. Just like streaming and downloading music from iTunes™, applications are streamed to a client device and run in a protected, virtual environment. Users have access to applications whenever and wherever they want — even when they are not connected to a network. Applications are cached locally in an ‘isolation environment’, rather than installed on the device, which eliminates application delivery conflicts and the need for extensive regression testing
Server-Side Application Virtualization
How it Works
To virtualize server-based applications, XenApp™ (the new name of Presentation Server™) abstracts the user interface (logical layer) from the application processing (physical layer) that occurs on a centralized, secured server. This technology is ideal for delivering client/server applications because it eliminates the complexities of deploying, managing, updating and securing a vast array of client software on each individual user’s access device. Instead, a single instance of the client application is installed on XenApp within the secure confines of the data center. The application executes entirely on the server, while its interface is displayed on the user’s device. Application delivery can be enabled for any user, regardless of device, network or location.
