Citrix has no released XenApp & XenDesktop 7.8 for download! If you wonder how this new release could help you then contact us at EnvokeIT for more information!

Customers with active Software Maintenance (SWM) or Subscription Advantage (SA)–effective February 17, 2016–can download XenApp 7.8 and XenDesktop 7.8 on

The XenApp and XenDesktop 7.8 release greatly simplifies application management, delivering a 90% time savings over traditional methods. It enhances the user experience, while introducing scalability improvements, enabling a 40% memory reduction and a 20% increase in CPU efficiency for select behavior. Plus new features strengthen security and compliance.

Simplify app management and delivery through new AppDisk technology

The 7.8 release includes exciting, new AppDisk app layering technology that lets you package and manage applications independent of your master desktop or server image. AppDisk alleviates the management complexity of multiple, departmental-based images by instantly layering applications onto your golden image based on different employee needs, making it easier than ever to deliver, install or update an application without changing or impacting the pristine, master image.

Save 90 percent of testing time by integrating AppDNA compatibility testing with AppDisk

Extending the app layering benefits of AppDisk, AppDNA for AppDisk instantly assesses the compatibility of the AppDisk applications with the associated master image, provides step-by-step remediation guidance to make any app compatible, while also reordering multiple assigned AppDisk layers for peak performance. Now you will be able to validate and remediate any OS or inter-app compatibility issues before delivering AppDisk applications to your user community.

This is one of the coolest things a part from the Workspace Cloud service that Citrix is working on. I’ve had the pleassure of trying this out and we at EnvokeIT have been doing a lot of tests of this Linux VDA tech preview.

Isn’t it great that both Microsoft and Citrix now seem to love Linux 🙂   (and yes, I manipulated these images so it’s not an official Citrix statement!)Richard_happy_when_Microsoft_and_Citrix_Loves_Linux

So this little blog post is just going to show of the capabilities and how nicely this integrates with the Citrix XenDesktop architecture. First of all I’d like to say thanks to my colleagues Björn Bekkouche and Peter Smali for letting me use their lab environment!

Before we get into showing how it works and looks I must just highlight that if you have any questions about how we can assist you to deliver Linux-based Terminal Servers or VDI’s to remote users in a secure and optimal just contact us at EnvokeIT here or pop me an email: richard at

This is great for all of you with Developers on Linux! Have them code from anywhere in a secure manner! They can run their Linux VDA in your datacenter, connect to it from an Receiver compliant device and code from them and you have your intellectual property secured internally instead of having them checking out Git repositories to their local devices etc.!

So what is XenDesktop for Linux? Well, to answer that really simple I assume that you have some basic knowledge of the Citrix XenDesktop architecture.. if you don’t then please read up on that a little before continue reading, one really good contribution to bulding your architecture is described in this Citrix Virtual Desktop Handbook or this Citrix XenDesktop – Blueprint. These contains a lot of valuable information that you shall think of and how to configure the environment to fulfill you use cases.

But overall think of the XenDesktop architecture of something like the following pictures (click to enlarge them). The first one shows the new model where we could run and take care of the VDA’s ourselves on-premise but leverage the Workspace Cloud service from Citrix so that we don’t anymore have to bother about the XenDesktop infrastructure components and the life-cycle management etc. of those. The second one is the more overall traditional architecture overview that you’d see of the different layers.



And as you see above this details the standard architecture wher you would have your Server or Desktop VDA’s in the resource layer hosting the desktops for your users to connect to, but they have all been Windows-based up until now!

Now with the Tech Preview we can actually install the Linux-based VDA on a Red Hat or Suse machine and access that through the SAME Delivery Controllers and StoreFront stores that also manage our Windows-based VDA’s.

And this is awesome! 🙂 We can leverage the already existing Windows-based architecture to just “hook in” our Linux-desktops as well and get users to conect through Receiver for Web, Receiver and even through the NetScalers if you need (works like a charm!!).

So as you can see here we have a nice little landing page for our entry points that are running different versions and access different environments etc.


So we have Peters entry point running one NetScaler version and theme: Read more…

Demystifying Citrix Excalibur Architecture – via @kbaggerman

A great blog post by Kees Baggerman! 🙂

For all XenApp admins and consultants out there Project Avalon will bring a big change as we are used to having XenApp servers running on the (what seemed to be) everlasting Citrix Independent Management Architecture and we’re heading to Citrix FlexCast Management Architecture (already included in XenDesktop at this moment) and will be included in the Citrix Excalibur Architecture.


When looking up IMA in the eDocs you’ll find:

Independent Management Architecture (IMA) is the underlying architecture used in XenApp for configuring, monitoring, and operating all XenApp functions. The IMA data store stores all XenApp configurations.

Basically IMA exists to manage the XenApp or Presentation Server farms by enabling the communications between servers. As stated it transfers information about all XenApp functions like licenses, policies, sessions and server loads. All management tooling within these versions of Citrix’s PS/XA rely on this service for information.

According to Communication ports used by Citrix Technologies IMA uses the following ports:

Ports Source Prot. Comment
2512 Common Citrix Communication Ports TCP Independent Management Architecture (IMA)
2513 Access Gateway 5.0 Controller administration TCP IMA-based Communication

As we can see IMA uses 2512 (by default) to communicate with other servers and the Access Gateway Controller uses 2513 (by default) for IMA-based communication. The port IMA uses can be changed or queried via the commandline tool IMAPORT.

Brian Madden did a blogpost way back in 2007 but it’s definition of IMA is still current:

Independent Management Architecture is:

  • A data store, which is a database for storing MetaFrame XP server configuration information, such as published applications, total licenses, load balancing configuration, MetaFrame XP security rights, and printer configuration.
  • A protocol for transferring the ever-changing background information between MetaFrame XP servers, including server load, current users and connections, and licenses in use

With the introduction of XenDesktop we got a new architecture called Flexcast Management Architecture. This new architecture has got an agent-based setup where we can install the operating system including the basic applications that need to be installed and after that we can install an agent. This agent registers itself to a controller and is offered through StoreFront to the end user.

This will be delivered by two different types of agents, one to support Windows Server OS’s and one for Windows Desktop OS’s.

Andrew Wood did an article on Excalibur and used this diagram to explain the architecture:

  • Receiver provides users with self-service access to published resources.
  • StoreFront authenticates users to site(s) hosting resources and manages stores of desktops and applications that users access – Web Interface as a platform is essentially resting, but it will cease to be.
  • Studio is a single management console that enables you to configure and manage your deployment, a dramatic reduction over the 23 consoles you could well have today. Studio provides various wizards to guide you through the process of setting up an environment, creating workloads to host applications and desktops, and assigning applications and desktops to users.
  • Delivery Controller distributes applications and desktops, manages user access, and optimizes…
