This article proposes an overview of the Adele system and also discusses other approaches and other systems. While most of our work on Configuration Management is covered, we have deliberately chosen to discuss in greater depth the Work Space aspect and the relationship between the Repository Space and the WSs. A Software Configuration Management (SCM)(More)
A single Model Transformation Chain (MTC) takes a high-level input model rooted in the problem domain and through one or more transformation steps produces a low-level output model rooted in the solution domain. To build a single “almighty” MTC that is in charge of every design, implementation and specific platform concern is a complex task. Instead, we can(More)
Versioning, in Software Engineering, has become synonym to the revision/variant graph, as proposed 20 years ago by SCCS. It is claimed here that this version graph is only a mechanism, and that it does not provide a clear description of the versioning concept. Consequently, the same mechanism is now used for very different purposes which lead (1) to a great(More)
Over the past decade the dynamic capabilities of self-adaptive software-intensive systems have proliferated and improved significantly. To advance the field of self-adaptive and self-managing systems further and to leverage the benefits of self-adaptation, we need to develop methods and tools to assess and possibly certify adaptation properties of(More)
Despite the valuable contributions on self-adaptation, most implemented approaches assume adaptation goals and monitoring infrastructures as non-mutable, thus constraining their applicability to systems whose context awareness is restricted to static monitors. Therefore, separation of concerns, dynamic monitoring, and runtime requirements variability are(More)
Cloud computing provides new opportunities to deploy scalable application in an efficient way, allowing enterprise applications to dynamically adjust their computing resources on demand. In this paper we analyze and test the microservice architecture pattern, used during the last years by large Internet companies like Amazon, Netflix and LinkedIn to deploy(More)
Large Internet companies like Amazon, Netflix, and LinkedIn are using the microservice architecture pattern to deploy large applications in the cloud as a set of small services that can be developed, tested, deployed, scaled, operated and upgraded independently. However, aside from gaining agility, independent development, and scalability, infrastructure(More)
In pervasive environments, users can potentially access a variety of services through their mobile devices. However, in order to use the new services, we need to adapt the functionality of these devices. To achieve it, we propose to load a bootstrap into them that is able to communicate with the services. However this bootstrap has to be adapted due to the(More)
