This Discussion will focus on the different levels of abstractions within the service interface layer and the importance of abstraction and role of layering when developing SOA-based IT solutions. At the end of the Discussion, you should be able to draw conclusions on why these abstractions and layering are essential and how they help the architect design SOA-based IT solutions. This knowledge will help you perform better as an architect when you work on SOA projects.
Discuss how layering in the service architecture helps an architect design an SOA-based IT solution.
