We present a description of the development and deployment infrastructure being created to support the integration effort of HARNESS, an EU FP7 project. HARNESS is a multi-partner research project intended to bring the power of heterogeneous resources ...

Quality is the cornerstone of high criticality systems, since in case of failure not only major financial losses are at stake, but also human lives. Formal methods that support model based-development are one of the methodologies used to achieve ...

Queueing network models are commonly used for performance modelling. However, through application development stage analytical models might not be able to continuously reflect performance, for example due to performance bugs or minor changes in the ...

Complex software systems are required to adapt dynamically to changing workloads and scenarios, while guaranteeing a set of performance objectives. This is not a trivial task, since run-time variability makes the process of devising the needed ...

In order to increase the frequency of software releases and to improve their quality, continuous integration (CI) systems became widely used in recent years. Unfortunately, it is not easy to evaluate the performance of a software release in such ...

In this paper we present our mechanism and tooling for the continuous deployment and resource provisioning of multi-cloud applications. In order to facilitate collaboration between development and operation teams as promoted in the DevOps movement, our ...

Cloud computing has been a game changer in the design, development and management of modern applications, which have grown in scope and size becoming distributed and service oriented. New methodologies have emerged to deal with this paradigm shift in ...

Software performance engineering heavily relies on application and resource models that enable the prediction of Quality-of-Service metrics. Critical to these models is the accuracy of their parameters, the value of which can change with the ...
