The Impact of Patterns on Services and Vice Versa

Design patterns are a concept which has contributed a lot to the advancement of the field of software engineering.

In this context we examine how both design patterns have influenced new services and how services have led to the introduction of new patterns. Both aspects are illustrated by various examples
