This will be composed of Citrix XenApp, StoreFront, Provisioning Services, XenServer, and NetScaler, and it will attempt to resemble real-world scenarios as closely as possible. Some components, such as NetScaler, are optional, albeit strongly recommended and will be marked as such throughout the book. So let's start with creating a description of the specifications of the environment. You can skip the next subsection on physical hardware if you already have a hypervisor in place.
To host hypervisors, you can use any enterprise servers that are certified by your hypervisor vendor. Citrix, VMware, and Microsoft have a Ready program that thoroughly tests and certifies hardware (visit http://www.citrix.com/, http://www.vmware.com/, or http://www.microsoft.com/ for more information).
