Citrix has released a whitepaper on how to optimize the Logon process for XenDesktop and XenApp. In this whitepaper guide Citrix will give you an understanding Optimizing the Logon Process for XenApp and XenDesktop
The logon process for users accessing virtual desktops as delivered through Citrix XenDesktop or virtual applications as delivered through Citrix XenApp involves a variety of communication checkpoints and component interaction. Depending on the user environment and access location there can be an array of Citrix, Microsoft and possibly third-party components involved in the logon process. In order to optimize user productivity and enhance the overall virtual application and desktop experience, Citrix Consulting developed this white paper specifically focused on the logon process, common cause for logon delays and optimizations for improving the amount of time required to execute the logon process.
For an administrator to assess the logon process within their respective environment, the administrator must ensure that they have a detailed understanding of the logon process. This paper outlines the logon process for XenApp and XenDesktop, with a particular focus on identifying those key areas that commonly slow down the logon process. Each step of the logon process and each piece of component communication is outline in detail. With a solid understanding of the logon process, the reader is then introduced to the common causes of logon delays. This section provides a high-level aggregate of the logon delays that Citrix Consultants have encountered on customer engagements.

The common causes of logon delays serve as a high-level checklist that provide administrators with a reference point for investigating logon delays within their environment, but there is typically a need for quantifiable metrics to help guide an administrator through the process of determining which environment modifications and troubleshooting tools can be used to validate the delays to prove that modifications to the environment improved the actual logon times. The Citrix Consulting Solution Center team drilled into some of the common causes of logon delays to provide tangible metrics that can be referenced in any XenApp and XenDesktop environments. This whitepaper details the results and methodology of the Citrix Consulting Solution Center.

Citrix Cloud Provider Pack for Citrix XenApp 6.5 is a powerful collection of enabling technologies, available exclusively to certified Citrix Service Providers (CSPs), makes it easy to set up “Windows-as-a-Service” hosting businesses that are simpler to run, less costly and better optimized for mobile devices.

App Orchestration Technology This groundbreaking new capability automates the design, configuration, deployment and lifecycle maintenance of Windows apps and desktops hosted by CSPs for multiple tenants, across multiple farms. App orchestration is a requirement in order to attain cloud-scale and cloud-economics. From a single interface, cloud provider admins can define a workspace, performance characteristics, network configuration, and isolation requirements, and have the orchestration engine complete the deployment – hands-free. When it comes time to update apps or desktop images, the admin simply points to the new image, and the app orchestration engine handles draining servers and migrating subscribers without manual intervention. In addition, a new update to Citrix CloudPortal Services Manager provides out-of-the-box support for App Orchestration, enabling the hosted desktop infrastructure to autonomically respond to account provisioning requests via CloudPortal. For additional information regarding this technology please visit Citrix eDocs. Please be sure to review the Quick Deployment Guide.
Seamless App Technology For decades, Citrix has led the industry in “seamless apps” – making an application that’s running in a remote datacenter integrate with a local desktop environment – where we make it practically impossible for an end user to tell whether an app is running locally on their device or virtually in the datacenter. The Cloud Provider Pack moves this technology forward for the future with new capabilities designed specifically for the cloud. With this latest technology, end users can now have their personal, local apps alongside private-cloud business apps from their employer, all seamlessly presented in a cloud-based desktop with standard productivity suites. This unique ability to stitch together personal, private and public cloud components is unprecedented and not only improves the end user experience, but also simplifies customer on-boarding for cloud providers. It is no longer necessary to migrate every app in the entire customer desktop environment to the cloud prior to rolling out cloud desktops; providers can move the easy ones first, transition more difficult ones later, and even leave some apps local as deemed appropriate by the business owner. Please be sure to review the Local App Access Readme and Local App Access guide.
Mobility Pack With millions of mobile devices and millions more Windows apps and desktops in use, everyone is looking for a way to bridge the gap – and have the experience be intuitive and friendly. While there are many ways to view a Windows desktop from a tablet device, making the experience usable and touch-optimized is another matter altogether. The Mobility Pack for XenApp 6.5 accomplishes this by transforming the standard Windows PC experience into a more touch-friendly interface, with larger icons, iOS and Android-native menus and options, and auto pop-up keyboard for text entry. There are dozens of clever enhancements in the Mobility Pack, as well as a complete SDK for customizing specific apps for mobility. These customizations can even extend to allowing hosted apps to interact seamlessly with mobile device features such as GPS, Camera, or SMS. (The Mobility Pack was first introduced in December 2011; the Cloud Provider Pack includes important updates.)
