How layering works
A layer is a collection of objects for an application or operating system (OS). Unidesk’s innovative layering enables IT to deliver applications that look, act and feel as if they are installed locally in the VM/Gold Image, but these application are actually stored in isolated virtual disks. IT can provision, patch, and update all desktops by simply updating a layer once.
There are three types of layers:
Single OS Gold Image
The OS layer is the first layer created in the unidesk environment. It is a central image which is used to deliver the Windows Operating System as a read only virtual disk that can be shared by any number of virtual desktops and Remote Desktop Session Hosts (RDSH).
Application layers simply contain your applications and are attached to to the OS layer. Unidesk lets you package any app as its own layer and add layers to desktops and session hosts in any combination to meet your users’ needs. Its quick, its easy and all apps behave as if they were locally installed.
The personalisation layer retains all user settings, customisations, documents, plugins and applications etc. that are set to the user’s local profile. All the data that is set up by the end user is automatically written in a personalisation layer, a writable, virtual disk that is associated with each VM so you can make changes to your OS and applications without compromising user experience.
