Citrix App Layering makes it easier to manage your Windows applications. Regardless of which hypervisor or provisioning service you use, Citrix App Layering can help you manage your applications and operating systems.
Citrix App Layering separates the management of your OS and apps from your infrastructure. With Citrix App Layering you can install each of your apps and operating system patches once, and use them as part of any image you deploy. You can publish Layered Images as open standard virtual disks usable in any environment. This allows you to maintain a single Windows installation, and a single copy of each application, that you use for all of your images across all of your virtual environments.
Citrix App Layering lets you to package any Windows app as a virtual disk Layer and deliver it, installation-free, to session hosts. With Citrix App Layering, you can:
New applications, application updates, and Windows patches can be delivered to an entire RDSH farm with a single image update.
Using the Citrix App Layering Management Console, you can:
The heart of the Citrix App Layering deployment is the App Layering apliance (aka Enterprise Layer Manager), a virtual appliance that you deploy in your environment. The App Layering appliance hosts the App Layering Management Console, a friendly interface where you create Layers, and then assign them to either Layered Images, or directly to users via Elastic Assignment.
With Citrix App Layering you can create OS, App, and Platform Layers once, and use them to create any number of Layered Images. You can then update the OS, app, or Platform software by adding a new Version to the Layer for each patch or update that you apply.
In App Layers you can deploy virtually any applications compatible with the OS. Each App Layer can include one or more applications. When it's time to upgrade an application, you can add a new version to the Layer for the latest update.
Platform Layers are designed to support your environment. A Platform Layer containing your hypervisor tools and settings makes it easy to create layers using VMs in your hypervisor environment. A Platform Layer containing your hypervisor, provisioning service, and connection broker software isolates App and OS Layers from the infrastructure where they will be published.
Layered Images for provisioning Session Hosts and servers
Image Templates are where you choose the Operating System and Layer assignments for an Image. You can include OS and App layers in any number of Image Templates. Using an Image Template and a Platform Layer, you can publish a Layered Image to your provisioning service, hypervisor, or network file share .
You can publish Layered Images as virtual disks to any location to which the appliance has access, and use the disks to provision as many servers as you need.
A Connector configured with the credentials for a specific location in your virtual environment, allows Citrix App Layering to publish the Layered Images and provision servers in a specific location.
