App Layering in Azure

Aug 30, 2017

Azure prerequisites

Before installing App Layering in Azure, be sure to meet the following prerequisites.

  • Network File Share (Azure specifics)
    A file share server in Azure will perform significantly better than an on-premise file share. Even though the Azure file share feature is not supported, you can use an existing network file share or create a new file share in the Azure environment.
    • Using Premium Storage is strongly recommended.
    • Only fixed VHD disks will deploy successfully.
  • Azure account and subscription
    To deploy and configure the App Layering appliance, you will need the credentials for an account that has administrative access to your Azure subscription. For more information, refer to the Microsoft Azure Sign in page.
  • Azure Resource Manager
    App Layering is designed to work with Azure’s new Resource Management (ARM) model. It does not support Azure’s Classic deployment model. All resources such as virtual network, file shares and OS machines that App Layering will work with must be created with Azure Resource Manager. For more information, refer to the Azure Resource Manager overview page.
  • Azure network topology
    Before deploying the App Layering appliance, you must define and create your Azure network topology. The appliance and its Network File Share must have network connectivity. However, the appliance does not require network connectivity to the Session Hosts that are created. A site-to-site connection between your corporate and Azure networks is recommended for accessing the Management Console on the appliance. For more information, refer to the Microsoft Azure Virtual Network page.

Storage requirements

  • 350-500 GB Storage Space
    The App Layering appliance uses local storage for temporary files and finalized layers. The more layers you create, the more space you need. However, if you run low on space, you can expand the size of the current disk, or add other disks to the appliance when needed.

  • 40-100 GB network file share (SMB)
    The file share connected to the appliance is used for upgrades, Elastic Layers, and cross-platform publishing. This space is easy to expand, if needed.

Operating System requirement

OS for Layered Images

You need a supported operating system freshly installed from ISO, to use in your OS layer. The OS layer is used to build all of your other layers and Layered Images. Preferably, the ISO should be imported from your hypervisor, so that the operating system is partially optimized for your environment.
