Overview of Desktop Pools
With Horizon, you can create desktop pools that include thousands of virtual desktops. You can deploy desktops that run on virtual machines (VMs) and physical machines. Create one VM as a Parent image, and Horizon can generate a pool of virtual desktops from that image. The Parent image is also known as a base image or a golden image.
There are two main types of virtual desktop pools: automated and manual. Automated desktop pools use a vCenter Server virtual machine template or snapshot to create a pool of identical virtual machines. Manual desktop pools are a collection of Server virtual machines, physical computers, or third-party virtual machines. In automated or manual pools, each machine is available for one user to access remotely at a time.
Advantages of Desktop Pools
Horizon offers the ability to create and provision pools of desktops as its basis of centralized management. If you use a vSphere virtual machine as a desktop source, you can automate the process of making as many identical virtual desktops as you need. You can set a minimum and maximum number of virtual desktops to be generated for the pool. Setting these parameters ensures that you always have enough remote desktops available for immediate use but not so many that you overuse available resources.
Using pools to manage desktops allows you to apply settings or deploy applications to all remote desktops in a pool. You can also specify how users are assigned desktops in a pool.
With single-user desktops, each virtual machine allows a single end-user connection at a time. In contrast, with session-based desktops, one RDSH server can accommodate many concurrent user connections.
We will walk through the process of creating an Instant Clone Desktop Pool. A clone is a copy of a Parent VM with a unique identity of its own, including a MAC address, UUID, and other system information. The VMware Instant Clone Technology improves and accelerates the process of creating cloned VMs over the previous View Composer linked-clone technology. In addition, instant clones require less storage and less expense to manage and update because the desktop is deleted when the user logs out, and a new desktop is created using the latest Parent VM image.
