This position paper presents a middleware framework to support the development of context-aware adaptive communication protocols that can be reconfigured according, not only to the local context, but also to the context of the remaining remote participants. The advantages of the framework are illustrated using the concrete example of an adaptive group(More)
The problem of self-optimization and adaptation in the context of customizable systems is becoming increasingly important with the emergence of complex software systems and unpredictable execution environments. Here, a general framework for automatically deciding on when and how to adapt a system whenever it deviates from the desired behavior is presented.(More)
This paper addresses the self-management of in-memory distributed data grid platforms. A growing number of applications rely in these platforms to speed up access to large sets of data. However, they are complex to manage due to the diversity of configuration and load profiles. The proposed approach employs an adaptation policy expressed in terms of(More)
There exists a growing class of distributed applications that require adaptive middleware services, i.e., services that are able to monitor changes in the execution environment and in the user's requirements, reacting to these changes by adapting their behaviour. This paper proposes modelling primitives that allow to describe the adaptation logic of(More)
There exists a growing class of distributed applications that require adaptive mid-dleware services, i.e., services that are able to monitor changes in the execution environment , and in the user requirements, reacting to these changes by adapting their behaviour. This paper presents a framework that supports the definition, implementation, and execution of(More)
