This volume contains the technical papers presented in the workshops, which took place at the 7th European Conference on Service-Oriented and Cloud Computing, ESOCC 2018, held in Como, Italy, in September 2018:Joint Cloudways and OptiMoCS Workshop; 14th International Workshop on Engineering Service-Oriented Applications and Cloud Services. Additionally the papers from ESOCC 2018 PhD Symposium and ESOCC 2018 EU Projects Track were included in the volume. The 22 full papers were carefully reviewed and selected from 34 submissions. The papers focus on specific topics in service-oriented and cloud computing domains such as limits and/or advantages of existing cloud solutions, future internet technologies, efficient and adaptive deployment and management of service-based applications across multiple clouds, novel cloud service migration practices and solutions, digitization of enterprises in the cloud computing era, federated cloud networking services.

Advances in Service-Oriented and Cloud Computing

Es gibt im Bereich der Softwaretechnik viele Werkzeuge, die den Programmentwicklungsprozeß unterstützen. Sie stellen die Korrektheit der Implementierung sicher, nicht aber ihre Effizienz. Die vorliegende Arbeit führt daher eine Methode ein, die es erlaubt, die Zeitkomplexität funktionaler Programme automatisch zu ermitteln. Die Grundidee dieser Methode besteht darin, ein funktionales Programm in ein System von Rekurrenzgleichungen zu übersetzen, dessen Lösung das Zeitverhalten des Programms angibt. Durch Einführung von bedingten Rekurrenzen und Rekurrenzfamilien ist es möglich, obere und untere Schranken für die Zeitkomplexität zu finden. Um die mittlere Zeitkomplexität zu bestimmen, müssen Wahrscheinlichkeiten dafür berechnet werden, daß im Programm vorkommende Bedingungen wahr bzw. falsch werden. Diese Wahrscheinlichkeiten werden anhand einer probabilistischen Semantik des Programms berechnet. Um möglichst genaue Schranken für die Zeitkomplexität zu erhalten, muß eine Abhängigkeitsanalyse durchgeführt werden. Dies ermöglicht eine genaue Analyse von Divide-and-Conquer-Programmen.

Abstract state machines (ASM) sharpen the Church-Turing thesis by the c- sideration of bounded resources for computing devices. They view computations as an evolution of a state. It has been shown that all known models of com- tation can be expressed through speci?c abstract state machines. These models can be given in a representation-independent way. That is one advantage of transferring these models to ASM. The main advantage is, however, to provide a unifying theory to all of these models. At the same time ASM can be re?ned to other ASMs. Stepwise re?nement supports separation of concern during so- ware development and will support component-based construction of systems thus providing a foundation of new computational paradigms such as industrial programming, programming-in-the-large, and programming-in-the-world. ASM 2004 continued the success story of the ASM workshops. Previous workshops were held in the following European cities: Taormina, Italy (2003); Dagstuhl, Germany (2002); Las Palmas de Gran Canaria, Spain (2001); Monte Verita, Switherland (2000); Toulouse, France (1999); Magdeburg, Germany (1998); Cannes, France (1998, 1997); Paderborn, Germany (1996); and H- burg, Germany (1994). The ASM workshops have had predecessors, e.g., the famous Lipari Summer School in 1993, whose in?uential outcome was the f- damental Lipari Guide.
