Components are widely used for managing distributed applications because they not only capture the software architecture of managed applications as an assembly of components but also permit to dynamically adapt these applications to changing environments. Following this approach, our practical experience in the Jade environment about developing an autonomic… (More)
This paper presents the design, implementation and evaluation of Jade, an environment for autonomic management of legacy software infrastructures. This environment relies on two main frameworks: a framework for the encapsulation of administrable resources, which provides the administered system's resources with a uniform management interface; and a… (More)
Distributed software environments are increasingly difficult to manage. This paper presents a middleware for the development of self-manageable and autonomic systems. Preliminary experiments for automatically adapting a cluster of replicated databases according to QoS requirements are reported.
Autonomic computing enables computing infrastructures to perform administration tasks with minimal human intervention. This wrap-up paper describes the experience we gained with the design and use of <scp>Jade</scp>---an architecture-based autonomic system. The contributions of this article are, (1) to explain how <scp>Jade</scp> provides autonomic… (More)
With the development of Internet-based business, Web applications are becoming increasingly complex. The J2EE specification aims at enabling the design of such web application servers. These servers have to ensure scalability and availability of the supported applications. Scalibility can be achieved using replication techniques or partitionning techniques.… (More)
