A survey on non‐functional concerns in web services

More and more organizations make parts of their information systems available to their business partners and often face integration and interoperability issues. To counter these problems, web services appeared as a promising technology to bridge the gap between organizations and their partners. While web services generally focus on the implementation of functional concerns (FC) such as ordering of goods, the reservation of flights, etc. also non‐functional concerns (NFC) such as security, reliable messaging, performance, and availability have to be addressed appropriately. The purpose of this paper is to identify web services' requirements.

In this paper the authors provide a survey on works in the area of NFCs in web services. After presenting a common terminology, the most important requirements in that context are presented. Further, the authors assess these works against the requirements.

The evaluation reveals that there is no approach that supports the requirements to a satisfying degree. Based on that, the authors motivate the need for a novel holistic approach to NFCs in web services.

The paper presents an extended version of one of the papers presented at iiWAS2010.
