VMwares’ Instant Clones technology with a touch of Citrix XenDesktop
Also know as Just In Time (JIT) desktops, or vmFork technology. In short, it enables you to clone an existing virtual machine in just a matter of seconds — close to one clone per second actually. Its technology is based on in-memory cloning of a Master virtual machine (which also means it shares the memory of the so-called parent virtual machine) and copy-on-write for rapid deploy purposes. As you can probably imagine, this approach offers some unique desktop provisioning options when combined with, let’s say a Citrix XenDesktop Virtual Desktop Infrastructure, or VDI in short. Do note however that initially Instant Clones are/were a feature of VMware Horizon version 7 (Enterprise edition) and upwards, it was VMware’s Project Orion that introduced Instant Clones to Citrix’s XenDesktop, which is still in tech preview.
How it works
As mentioned, a Just In Time desktop is based on a Master virtual machine. When the vmFork technology is put to work the following happens, check out the image below as well.
