Enterprise Architecture Driven and User-Friendly SaaS Service Selection

In the last decade the number of cloud services has grown significantly, and its nature challenges the traditional process of requirements elicitation for software solutions. Most of the conducted cloud research address non-functional requirements, such as payment strategies, performance or security. Methods are required which provide an appropriate level of abstraction for describing the functional aspects of cloud services. We suggest an approach which exploits the potential of enterprise architecture modeling for cloud service selection. This study contributes to cloud service selection in two ways. First, we suggest a concept for the description of functional requirements for vertical SaaS services. Second, we provide a method that enables various kinds of stakeholders to describe their requirements considering their individual knowledge level.
