This chapter covers advanced functions, which go one step deeper that the use-cases and functions covered in Chapter 2, IBM® SmartCloud® Enterprise, and Chapter 3, Getting Started. First let's merge the concepts showed in the figures in afore mentioned chapters into one figure containing them all, as the following figure depicts.
