PoC Guide: Learn how to use Citrix App Layering and the Azure Deployment Connector to create and deploy an image with Citrix Machine Creation Services(MCS) in Microsoft Azure

  • Contributed By: Steve Beals Special Thanks To: Tyler Benoit, Daniel Lazar

Overview

Citrix App Layering is a process to create and a technology that allows you to simplify the management of virtual images. App Layering enables you to create a virtual desktop for users, a complete virtual machine for Citrix Machine Creation Services (MCS), or an entire virtual disk to use with Citrix Provisioning (PVS). Citrix App Layering creates layers that are containers for the file system objects and registry entries unique to that layer. These layers are virtual disks, created and updated independently of each other, and are compiled into an image. There are five different types of layers:

  • OS Layer: The Windows OS is installed in the OS layer. You can reuse the same OS layer with all compatible platforms and app layers.
  • Platform Layer: All software and tools are installed into this layer. For example, specific on-premises or cloud tools or antivirus software. A platform layer for each part of your infrastructure can be created if you use more than one hypervisor.
  • App Layer: Applications get installed in the App Layers. Typically a single application is installed on each App Layer, though you can include more.

This Proof of Concept guide is designed to help you get started with Citrix App Layering within a Microsoft Azure environment. The guide walks you through the following to begin using Citrix App Layering:

  1. Install the Citrix App Layering appliance in Microsoft Azure.
  2. Access the Citrix App Layering management interface.
  3. Set up an SMB file share.
  4. Configure Azure Deployment Connector Configuration.
  5. Create an OS Layer.
  6. Create a Platform Layer.
  7. Create an App Layer.
  8. Publish the layered image.
  9. Create a machine catalog and delivery group from the new image.

Architecture Overview

app-layering-architecture.png

The Citrix App Layering appliance, also known as the Enterprise Layer Manager (ELM), creates and manages layers which can be assigned to users or machines. With the Citrix App Layering appliances, administrators can create different layers such as application layers, OS layers, and platform layers, which will be kept in a repository managed by the Citrix App Layering appliance. Administrators can create a layer image with the combination of a specific OS layer and a few application layers as per the requirement of the end users. During the layered image creation process, the different layers are merged to form a single master image, which can be used by Citrix Machine Creation Services. Once the machine catalog is created administrators can create or provision machines which can be assigned to the users through the delivery group. Users then can launch the desktops when logged into Citrix Workspace.

For additional information on Citrix App Layering, review the Citrix App Layering Reference Architecture.

Deployment Steps

Install App Layering Appliance

  1. Log in to Citrix downloads and download the latest version of the App Layering installation package for your hypervisor. We are using Microsoft Azure for our deployment, so we download the Microsoft Azure Appliance Installation Package.

    poc-guides_app-layering_app-layering-download.png

    Note:

    The Azure App Layering download package requires 31 GB of space when uncompressed.

  2. Extract the zip file to a folder on your local drive.

    poc-guides_app-layering_app-layering-extract.png

  3. Open Windows PowerShell and confirm that the Azure PowerShell module is installed by running the Get-InstalledModule -Name Az command.
