Abstract

The advances in modern technology development and future technology changes dictate new challenges and requirements to the engineering and provision of services and service-based systems (SBS). These services and systems should become drastically more flexible; they should be able to operate and evolve in highly dynamic environments and to adequately react to various changes in these environments. In these settings, adaptability becomes a key feature of services as it provides a way for an application to continuously change itself in order to satisfy new contextual requirements. Events and conditions triggering application adaptation include: changes in the infrastructural layer of the application due to quality of service changes; changes of the (hybrid) application context and location; changes of the user types, preferences, and constraints that require application customization and personalization as a means to adapt the application behavior to a particular user; changes in the functionalities provided by the component services that requires modifying the way in which services are composed and coordinated; and changes in the way the service is being used and managed by its consumers, which in turn leads to changes in the application requirements.
