Three ways to deploy applications using Horizon Mirage application layers

Application layers in Horizon Mirage are a pretty flexible way to deploy applications. In fact you have three ways of deploying applications using Mirage application layering:

  1. Deploy applications using native application layer functionality
  2. Deploy ThinApps using application layers
  3. Deploy application installers using application layers

The first way is obviously the preferred way for any application you want to deploy and use natively. While I normally recommend to install core applications in the base layer some applications may be better suited when deployed via application layers. Examples are departmental apps or applications which are only deployed to a few users. Also applications that need to be updated often and need to be used natively (not virtualized) are good application layer candidates.

The second option is to use ThinApp inside an application layer. Using ThinApp has many great benefits compared to the native application layer deployment. For example running different application versions at the same time, isolate applications to prevent conflicts, get old Windows XP applications up and running on Windows 7 more easily, run old versions of Internet Explorer and browser plug-ins and so on.
While application layers are not yet optimized to deliver ThinApps (you still need to reboot) this is nevertheless a viable option. Especially if you have no other deployment system or deploying ThinApps to branch office users. When deploying ThinApps to branch offices using Mirage application layering the data will be cached on the Mirage branch reflector. Therefore it will only be transferred over the WAN once. This of course is true regardless of which way you use application layers.

The third way is a bit special. When deploying application layers Mirage allows you to run so called post-application layer deployment scripts. Using these scripts you can do more or less anything you want after an application layer is deployed. So why not install an application this way? This may seem a bit cumbersome at first but makes sense for some applications, i.e. to deploy disk encryption software which is not supported using application layers. Or deploy applications which do not work with application layers yet, like VMware Workstation/Player or Microsoft SQL Server. Again deploying applications this way is highly optimized for branch offices scenarios. The application installation files which are placed inside the application layer and the post-script itself are cached on a branch reflector.

Looking at all three options you see that Mirage application layers can be used in many ways. You can deploy any type of application using application layers.
