Distributed software environments are increasingly complex and difficult to manage, as they integrate various legacy software with specific management interfaces. Moreover, the fact that management tasks are performed by humans leads to many configuration errors and low reactivity. This is particularly true in medium or large-scale grid infrastructures. To address this issue, we developed Jade, a middleware for self-management of distributed software environments. In this paper, we report on our experiments in using Jade for the management of grid applications.
Current computing platforms become more and more complex for users to use. To simplify configuration and deployment of applications on these infrastructures tools are necessary. Current deployment tools lack of maturity for largescale deployment. For example a grid environment leads to a great diversity. Deploying an application on a grid from a single centralized machine is not adapt. So, decentralization of management is needed. We present in this paper a hierarchical deployment with the TUNe autonomic management system. This approach is based on UML formalisms.
We propose and evaluate MoRAI (Mobile Read Access in Intermittent internet connectivity), a distributed peer-topeer architecture organized in three levels dedicated to RDF data exchanges by mobile contributors. We present the conceptual and technical aspects of this architecture as well as a theoretical analysis of the different characteristics. We then evaluated it experimentally and results show the relevance of considering geographical positions during data exchanges and of integrating RDF graph replication to ensure data availability in terms of requests completion rate and resistance to crash scenarios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
