App Layering

What’s new in App Layering 4.14

Release date: September 25, 2018

This release includes the following features and improvements.

  • User layer feature is generally available! The user layer feature, which allows you to persist user data and settings, is now generally available! To learn more about this feature, click here.

  • Support for vSphere vCenter 6.7.x: vSphere vCenter 6.7.x is now approved for use with App Layering.

  • Azure Standard_D4s_v3 virtual machine size available for new deployments: When deploying a new appliance in Azure, the virtual machine size of Standard_D4s_v3 is now recommended. This size runs on newer generation hardware.

  • Faster login times for users who have Elastic layers: Users who have Elastic layers will experience faster login times. A new default setting loads Elastic layers only after login completes. If an Elastic layer doesn’t load correctly with this new default in place, you can select the new Elastic Layer Compatibility Mode, to override the default and allow the layer to start loading before login completes.

  • Search indexing options available upon login: Search Indexing options established in App layers or set by a user are now present and functional upon login.

  • Publish layered images directly from the image template: When creating or editing an image template, users now have the ability to publish layered images directly from the wizard’s Confirm and Complete tab, with a single click.

Labs features in this release

Labs features are previews of potential functionality for future releases. While a feature is in Labs, do not use it in production. There is no guarantee that a Labs feature will become part of the product, nor that the feature will work as originally designed if and when it is released.

The Labs features available in this release include the following:

  • App layers can be assigned as elastic layers on layered images that use a different OS layer: Until now, Elastic layer assignments required that the app layer assigned use the same OS layer that was used to create the App layer. Now you can try assigning an app layer as an Elastic layer on a layered image that uses a different OS layer.


    There is no guarantee that an App layer can work on a different OS layer than the one used to create it. If there are issues, you can disable this feature and allow the app layer to be used only with the OS that you used to create the layer.

To use a Labs feature, enable it first.
