Component-based architectures are natural for Cloud computing. However, few current software development frameworks are exploiting this fact. A proof-of-the-concept implementation of an open-source Platform-as-a-service dedicated to the development of component-based applications is shortly presented in this paper.
Usage scenarios involving services from multiple Clouds, like in Federations or Markets of Clouds, are imposing the development of complex middleware to hide the heterogeneity at the underlying Cloud technologies and services in order to attract Cloud application developers. This paper points towards the specific modules of a recent open-source and… (More)
Knowledge discovery from databases (KDD) is a complex process composed of several phases: business understanding, data understanding, data preparation, modeling, evaluation and deployment. For each of the phases, there are many algorithms and methods available, the end-user having to select one of them. The AgentDiscover is a multi-agent based intelligent… (More)
Cloud service abstractions are currently used to hide the underlying complexity given by existing technologies and services, in hope of facilitating the enacting of Cloud Federations and Marketplaces. In particular, resource management systems dealing with multiple Cloud providers need to expose an uniform interface for various services and to build… (More)
The task concept is a widely used pattern in reasoning systems. Unified Problem-solving Method Development Language (UPML) is a framework allowing building libraries of generic problem solving components. This paper proposes several improvements in this framework based on observations when modeling a concrete application. It starts from describing in UPML… (More)
