In a Grid context, service providers are strategically interested to manage the level of performance that can be oered to service consumers. This paper introduces a model-driven approach for predicting, at design time, and managing, at execution time, the performance characteristics of applications based on Grid Services. The approach is based on the automatic generation and evaluation of performance models from design models of UML type. An example application is illustrated to show the eectiveness of the proposed approach.}, keywords = {Applications, Automatic generations, Design models, Design time, Execution time, Grid, Grid computing, Grid contexts, Grid environments, Grid services, Grid-based applications, LQN, Model-driven approaches, Performance analysis, Performance characteristics, Performance managements, Performance models, Service providers, Service-oriented, Software applications, Software engineering, Spontaneous emission, Systems analysis}, isbn = {9780889867154}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-62849087032\&partnerID=40\&md5=497dc66a800e3d14123b851fc9cec6d7}, author = {Andrea D{\textquoteright}Ambrogio and Conticelli, L.} } @conference {Ambrogio2008292, title = {A UML profile for modeling software applications based on grid services}, booktitle = {Proceedings of the IASTED International Conference on Software Engineering, SE 2008}, year = {2008}, note = {cited By 1}, pages = {292-297}, abstract = {Grid environments and software applications based on Grid Services are currently receiving a strong consid- eration. Nevertheless the development of such appli-cations is still di cult and error-prone because of the lack of appropriate notations based on widely used lan-guages such as UML. This paper introduces a classi- cation of services that interact in Grid environments and proposes an UML extension for Grid service- oriented applications. The extension is carried out by use of a UML pro le, that is a lightweight standard ex- tension mechanism that allows to specify the roles of the di erent services within UML diagrams and that can easily be incorporated into UML-based integrated development environments. The proposed pro le facil- itates the development of applications based on Grid Services and increases their reusability and maintain- ability. An example application is introduced to show how the pro le can be e ectively used to annotate ac-tivity diagrams, component diagrams and deployment diagrams.}, keywords = {Applications, Deployment diagrams, Error-prone, Graphic methods, Grid, Grid computing, Grid environments, Grid services, Integrated development environments, MDA, Modeling softwares, Positive ions, Reusability, Service-oriented, Software applications, Software engineering, Spontaneous emission, Standardization, Uml diagrams, UML extensions, UML profile}, isbn = {9780889867154}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-62849118302\&partnerID=40\&md5=7c2372c396d896a454b5c2251fd400e3}, author = {Andrea D{\textquoteright}Ambrogio and Conticelli, L.} }
