In the previous chapter you learned how to identify and design services.
This chapter starts by revisiting the classifi cation of services that was explained
in the previous chapter, the aspects on which it is based and how the classifi cation
can be applied. The chapter briefl y discusses why it is important to classify
services based on your needs and what aspects can be used to create a
classifi cation of services.
You will then learn how services can be combined into larger services, which is
called service composition. Composition is one of the building blocks for the
classifi cation scheme.
Next, the different elements of the classifi cation scheme will be discussed in detail.
Finally, the chapter revisits the design principle of isolation and explains why
composition and isolation is a good match.
