SOAdapt: A process reference model for developing adaptable service-based applications

Abstract

a b s t r a c tContext: The loose coupling of services and Service-Based Applications (SBAs) have made them the ideal platform for context-based run-time adaptation. There has been a lot of research into implementation techniques for adapting SBAs, without much effort focused on the software process required to guide the adaptation. Objective: This paper aims to bridge that gap by providing an empirically grounded software process model that can be used by software practitioners who want to build adaptable SBAs. The process model will focus only on the adaptation specific issues. Method: The process model presented in this paper is based on data collected through interviews with 10 practitioners occupying various roles within eight different companies. The data was analyzed using qualitative data analysis techniques. We used the output to develop a set of activities, tasks, stakeholders and artifacts that were used to construct the process model. Results: The outcome of the data analysis process was a process model identifying nine sets of adaptation process attributes. These can be used in conjunction with an organisation's existing development lifecycle or another reference life-cycle. Conclusion:The process model developed in this paper provides a solid reference for practitioners who are planning to develop adaptable SBAs. It has advantages over similar approaches in that it focuses on software process rather than the specific adaptation mechanism implementation techniques.

Toward a Theoretical Foundation for Experience Design in Tourism

“…These include the spiral model (Boehm 1986), scrum (Schwaber 1995), feature-driven development (Coad, Lefebvre, and DeLuca 1999), rational unified model (Kruchten 2003), and many more. These iterative designing processes have been applied in computing and information technology fields to design for information management services (Lucio-Nieto et al 2012), service-based applications (Lane, Bucchiarone, and Richardson 2012), and other web services (Millard et al 2009). Finally, it is suggested in these studies that design research is integrated in the entirety of designing process as information gathering (i.e., typically through observation and user testing) and analysis processes are situated in all iterations of the designing stages.…”

BASBA: A framework for Building Adaptable Service-Based Applications

“…Adaptation can be defined as a process of modifying an SBA in order to satisfy new requirements and to fit new situations dictated by the environment on the basis of adaptation strategies designed by the system integrator [3,21]. Conventionally, dynamic adaptation has been managed within the application logic at the code level.…”

Control system and data acquisition for the remote monitoring of the personnel in the ATLAS experimental infrastructure at CERN

“…Service-based applications are composite applications which are created and based on multiple software services, as Lane et al mention [52]. Software services or services are computational components that use computer networks to function and operate.…”

“…This is an example of the large set of cases where applications that require assembling of various services need to be adaptable to maintain the high quality of their multiple service and their combination. The need for the adaption of service-based applications may concern the component services or the context of an SBA, derived from the following changes that may occur as they were mentioned by Lane et al [52]:…”

“…Dynamic adaptation on the other hand, allows the adaptation logic to be modified or replaced during runtime without shutting the system down. Dynamic adaptation is more flexible than static adaptation, but it requires some process to guide the manual intervention during runtime"[52].From the perspective of Bucchiarone et al, there are different types of Adaptation that they distinguish as follows: Perfective Adaptation, Corrective Adaptation, Adaptive Adaptation, Preventive Adaptation and Extending…”
