They will be applicable or not, depending of the precise circumstances in your environment, so you need to figure out a lot of things. If you are now building such a system, you also have the task to find where to locate all basic resources that will be combined to produce the product(s); this is the layout problem.

Without more details it is impossible to say what principles to use, but start by browsing the web using the key words you know you need.
