“…For purposes of evaluating the proposed methodology and the Cloud Data Migration Tool, we conducted a case study in the eScience field using an integrated and interactive Scientific Workflow Management System (SWfMS) developed in the context of the SimTech project [14], [15]. This SWfMS is based on conventional workflow technology adapted to the needs of scientific workflows and implemented as a distributed system.…”

Abstract-Migrating an existing application to the Cloud is a complex and multi-dimensional problem requiring in many cases adapting the application in significant ways. Looking specifically into the database layer of the application, i.e. the aspect providing data persistence and manipulation capabilities, this involves dealing with differences in the granularity of interactions, refactoring of the application to cope with remote data sources, and addressing data confidentiality concerns. Toward this goal, in this work we present an application migration methodology which incorporates these aspects, and a decision support, application refactoring and data migration tool that assists application developers in realizing this methodology. For purposes of evaluating our proposal we present the results of a case study conducted in the context of an eScience project.

“…Identifying the life cycle phases of production workflows has led to faster advances in the standardization efforts in this area, which makes us believe that a detailed life cycle definition for eExperiments positioned within the life cycle of eScience will benefit the eScience community enormously. However, such a definition is still missing [19].…”

eScience is the field trying to provide IT support to scientists throughout the life cycle of scientific experiments. The major focus is on shortening the time to new discoveries and revealing knowledge about natural phenomena by providing software systems for different scientific tasks and for many domains. In this field, however, one can observe that there are no standardized and systematic approaches for developing the systems dealing with the processing and analysis of the large amounts of scientific data. In this paper we introduce eScienceSWaT, a software engineering methodology that aims at providing a systematic and userfriendly approach for building software applications for scientific experiments. The proposed approach considers the existing knowledge from computer science and software engineering but does not require scientists to be specialists in these fields. Furthermore, we present an architecture of a composable system enabling eScienceSWaT. The system is meant to guide scientists in developing their experiments and features decision support capabilities based on patterns. Both the methodology and the architecture apply approaches from Enterprise Computing, Cloud Computing and Software Engineering. In order to demonstrate the suitability of eScienceSWaT, we apply it to a scenario from the field of scientific simulations.

“…The architecture components used during the modeling phase are the modeling and monitoring tool [8] and the bootware running locally on the user's machine, and the service package repository, the service registry and the user registry running in a Cloud environment. These components are active during all life cycle phases.…”

Abstract-Service selection is an important concept in service oriented architectures that enables the dynamic binding of services based on functional and non-functional requirements. The introduction of the concept of on-demand provisioned services significantly changes the nature of services and as a consequence the traditional service selection process does not fit anymore. Existing approaches for service selection rely on the always on semantic of services, an assumption that is not valid for on-demand provisioned services. We tackle this problem by adapting the traditional service selection process and by defining an additional step covering the changes introduced by the concept of on-demand provisioning. Our solution comprises an extended architecture for on-demand provisioning, a metamodel for a service registry, and a detailed definition and discussion of the adapted and extended service selection process. The work presented in this paper allows keeping the advantages of dynamic service binding at runtime and combining them with the advantages of Cloud computing exploited through the concept of on-demand provisioning.
