One challenge I ran across when deploying a UniFi network in my own home was, where to place the controller? The UniFi controller from Ubiquiti networks can be run on almost any hardware. The controller functions best when it is always running on the network, eliminating the option of running it on my workstation. They do offer a device called a Cloud Key, but the first generation was ripe with problems and the 2nd generation is a little too pricy to use just for the network management aspect, although it does start to show value if you use it as an NVR for UniFi cameras.
