Automating the Citrix App Layer

Introduction:
If your daily job has anything to do with virtual workspaces, you definitely have heard something about app layering. App layering is seen as the replacement for the ‘old’ application virtualization solutions like Microsoft App-V and VMware ThinApp.
While app layering is a good solution for most of the usual issues that come with running many applications on the same machines, it still takes a lot of time to create all those layers.
So together with automation-aficionado Chris Twiest we asked ourselves the question:
‘Is it possible to automate app layer creation?’

This blog will focus on the automation of creating app layers with Citrix App Layering, while Chris Twiest focused on doing the same with VMware App Volumes, the result of which you can find here. This blog is also a precursor to our presentation at the Expert 2 Expert Virtualization Conference in Athens (link).

Citrix XenDesktop 7.x VDI deployment with PowerShell using vSphere, local storage and PVS

Introduction:
At a customer a while back we had an Citrix XenDesktop 7.9 environment. VMware vSphere 6.0 was used as hypervisor, Citrix Provisioning Services 7.9 for deployment and Microsoft Windows 10 as OS for the virtual desktops. Since these desktops were non-persistent we were able to use the local solid state storage in the hypervisors. This did however present some challenges when it came to the deployment of the virtual desktops. We (my colleague Leon van Efferen and myself) ended up with a PowerShell script that did just about everything.

In this post I will explain what the script does and what you need to do to use it in your own XenDesktop/PVS/vSphere environment. You can find the actual script at the end of the post.
Keep in mind that the customer used VMware vSphere (XenServer or Hyper-V were a big no-no for unknown reasons) and therefore the script only contains the commands for vSphere (PowerCLI 6.x). If you would like to use it for other hypervisors, feel free to alter it in any way and present it as your own on your own blogsite.
