This machine will be referred to as the Master Target Device. This is the process of configuring and installing all desired software (including applications) and additional components onto a physical and/or virtual machine of choice, like we would normally do when creating a master image in fact it is not uncommon to use Microsoft SCCM, or a similar solution for this. It all starts with the actual vDisk, or the creation of it. You could easily provision several hundreds or thousands perhaps of physical and/or virtual machines from ‘just’ two provisioning servers, although more would be preferred. The idea behind this project? Before commenting, read the introduction blog post here You will always have at least two provisioning servers for HA purposes, or more depending on the size of your deployment and the number of target devices that need to be serviced. Simply put, a single read-only (hence the single image management remark earlier) vDisk or virtual disk will be streamed over the network to multiple so-called target devices, which can be XenApp servers or XenDesktop VDI-based VMs. Provisioning services is based on software streaming technology. Note that this chapter is primarily meant to give you a high-level overview of Citrix Provisioning Services, as I’m not going to cover all the ins and outs that come with setting up, managing and maintaining a PVS Farm some details will be included, though. MCS will be discussed in the next chapter, for now I would to spend a minute or two talking about PVS: what it is, how it works, and what some of the advantages are, or can be. However, ongoing maintenance will always be a challenge.Īnd third, we can leverage single image management in the form of either Citrix Machine Creation Services (MCS) and/or Citrix Provisioning Services (PVS). Second, you can use an automation tool of some sort (or script it yourself) to install and update your XenApp servers and/or XenDesktop VDI machines, which isn’t that uncommon. For one, we can decide to install and manage everything manually, like we are used to doing on our home PCs. When it comes to delivering the base Operating System within Citrix-orientated environments we have a couple of options to choose from.
