Design for Adaptation of Service-Based Applications: Main Issues and Requirements

A White Box Perspective on Behavioural Adaptation

“…(ii) It allows us to relate approaches presented independently and in different areas but sharing, essentially, the same category of control data. This is, e.g., the case of the approaches based on modes of operation proposed by the Software Engineering [11] adaptation coordination strategies adaptation strategy 4.1 [48] adaptation rules adaptation strategy 5.3 [15] architecture architecture 3.1 [46] architecture architecture 3.2 [60] architecture architecture 3.2 [66] module stack architecture 3.2 [22] current workflow architecture 3.2 [7] connectors architecture 3.2 [11] architecture architecture 4.1 [76] effector channel architecture 4.3 [48] set of activities architecture 5.3 [61] entire programs entire program 4.1 [55] rewrite rules entire program 4.2 [35] processes entire program 4.3 [30] processes entire program 4.3 [28] features operation mode 4.1 [53] regions operation mode 4.1 [83] operation mode operation mode 4.1 [1] active configuration operation mode 4.1 [72] active configuration operation mode 4.1 [19] control proposition operation mode 4.1 [82] steady state programs operation mode 4.1 [42] state space zones operation mode 4.1 [33] graph rewrite rules operation mode 4.2 [80] base level Petri net operation mode 4.3 [51] adaptor processes operation mode 4.3 [16] adaptable (local) processes operation mode 4.3 [69] context stack operation mode 5.1 [36] advices operation mode 5.2 [44] policies operation mode 5.3 community with paradigm-oriented approaches and by the Theoretical Computer Science community with automata and process-algebraic approaches. (iii) It allows us to compare approaches apparently similar (and falling in the same section) but based on different categories of control data.…”

“…A life-cycle for service-based applications where adaptation is a first-class concern is defined in [22]. Such life-cycle continues during runtime to cope with dynamic requirements and the corresponding adaptations.…”

“…Such life-cycle continues during runtime to cope with dynamic requirements and the corresponding adaptations. In addition to the life-cycle, [22] focuses on the identification of a number of design principles and guidelines that are suitable for adaptable applications. Essentially, adaptation is understood as the modification of the workflow implementing a service-based application, from substituting individual services by equivalent ones, to recomposing a piece of the workflow to obtain an equivalent result.…”

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

“…Unfortunately, most of the approaches identified the in SLR [7] and the ad hoc search [23] are non-holistic and lacking the required processes to fully guide SBA adaptation. Each of these publications as well as two other papers from Bucchiarone et al [24,14], were searched, resulting in a total of 50 SBA adaptation activities (see Appendix A).…”

“…In summary, each of these four approaches focused on the analysis and design processes without consideration for any other development or runtime processes. The solution proposed in [14] can be considered as a first step in this direction. The authors of this paper have proposed a process model for SBAs where adaptation is a first class concern.…”
