Citrix App Layering makes it easier to manage your applications. App Layering can help you manage your applications and operating systems regardless of which hypervisor or provisioning service you use. App Layering separates the management of your operating system and apps from your infrastructure. With App Layering, you can install each of your apps and operating system patches one time, and then use them as part of any image you deploy.
