Virtualization Technology News and Information
Citrix Releases App Layering (Formerly Unidesk) Version 4.1.0

Back in January, Citrix announced the acquisition of Unidesk, a company creating its own layering technology that would simplify application and OS management for organizations of all sizes. 

Fast forward, and Citrix is now announcing that Citrix App Layering, the company's new name for what was Unidesk, is a Citrix Cloud service being made available for anyone to try and for eligible Citrix customers to deploy.

Citrix App Layering provides open application management across all end user computing solutions, hypervisors, and clouds.  And it's an open solution for Windows application packaging and image management.  With Citrix App Layering, IT administrators can package any Windows app as a virtual disk container ("layer") in minutes for install-free delivery to session hosts and virtual desktops on any hypervisor or cloud.  With Citrix App Layering Elastic Layering, applications are attached dynamically at logon to pooled, non-persistent desktops, remote desktop session host (RDSH) sessions, based on user policy.  This enables Users' sessions to be personalized with the applications they need.

What's new in the 4.1.0 release?

  • Improved performance when Creating App Layers using XenServer and Nutanix. You can configure the XenServer and Nutanix Connectors to cache boot and packaging disks and reuse them. Once these disks have been cached as part of creating your first App Layer, the time it takes to create subsequent App Layers is cut in half.
  • OS images can be imported directly from your vSphere or XenServer VM. When using a vSphere or XenServer connector to create an OS Layer, the OS image can now be imported directly from a VM.
  • User Layers can now be stored in multiple file shares of your choice.
  • Automatic shutdown for MCS or View. When you publish a Layered Image to MCS or View, the image is shutdown automatically so that a snapshot can be taken. For details, click Publish to MCS, and Publish to View.
  • The PVS connector allows canceling of long running operations. The PVS connector now provides the ability to cancel long running operations, for example, copying the VHD to a PVS datastore. The Cancel operation automatically cleans up unnecessary files, such as vDisks, from failed publish operations.
  • Improved search for Platform Layers. You can now search for Platform Layers that were created using a particular OS Layer.
  • Upgrades are automatically downloaded, and you choose when to install them. When App Layering software upgrades become available, it is automatically downloaded to the appliance. When the download completes, you will be notified that an upgrade is available the next time you log into the Management Console.
  • When upgrading to this release, the default passwords for the Admin accounts must be changed (a one-time event). When you install this release or upgrade to it, you will be required to change default passwords for the administrator accounts, including the Management Console Administrator, the Appliance Configuration Tool administrator, and the Linux root user.

Additional operating systems and session environments will be supported going forward.
  • Access the Management Console via Citrix Cloud (Labs). You can access the App Layering Management Console via the Citrix Cloud App Layering Manage tab. For steps and known issues, click here, if this is a new installation, or here if you are upgrading from a Unidesk 4.0.x release.
