This paper introduces Automat, a testbed architecture and prototype for research in autonomic services and hosting centers. Automat is an interactive web-based laboratory in which users allocate resources from an ondemand server cluster to experiment with controller policies for sense-and-respond monitoring and adaptation by hosted services and, crucially, by the hosting center itself. Users ma...

Cloud computing is an evolving utility computing mechanism in which cloud consumer can detect, choose and utilize the resources (infrastructure, software and platform) and provide service to user based on pay per use model as computing utilities. Current computing mechanism is effective, particular for medium and small cloud based companies, in which it permits easy and reliable access to cloud...

The work reported in this paper proposes a Swarm-Array computing approach based on ’Intelligent Agents’ to apply autonomic computing concepts to parallel computing systems and build reliable systems for space applications. Swarm-array computing is a swarm robotics inspired, novel computing approach considered as a path to achieve autonomy in parallel computing systems. In the intelligent agent ...

Autonomic computing is gradually becoming accepted as a viable approach to achieving self-management in systems and networks, with the goal of lessening the impact of the complexity crisis on the computing industry. The authors propose the integration of high level selforganisation features into an Application Directed Adaptive Framework (ADAF), an autonomic-oriented software development proces...

Virtual laboratories can be characterized by their longlasting, large-scale computations, where a collection of heterogeneous tools is integrated into data processing pipelines. Such virtual experiments are typically modeled as scientific workflows in order to guarantee their reproduceability. In this chapter we present JOpera, one of the first autonomic infrastructures for managing virtual lab...

Autonomic computing systems are designed to be self-diagnosing and self-healing, such that they detect performance and correctness problems, identify their causes, and react accordingly. These abilities can improve performance, availability, and security, while simultaneously reducing the effort and skills required of system administrators. One way that systems can support these abilities is by...

Autonomic Computing is a promising new concept in system development. It aims to (i) increase reliability by designing systems to be self-protecting and self-healing; and (ii) increase autonomy and performance by enabling systems to adapt to changing circumstances, using self-configuring and self-optimizing mechanisms. This paper discusses the type of system architecture needed to support such ...

The design of modern computing systems largely exploits structured sets of declarative rules called policies. Their principled use permits controlling a wide variety of system aspects and achieving separation of concerns between the managing and functional parts of systems. These so-called policy-based systems are utilised within different application domains, from network management and autono...

An approach to the management of non-functional concerns in massively parallel and/or distributed architectures that marries parallel programming patterns with autonomic computing is presented. The necessity and suitability of the adoption of autonomic techniques are evidenced. Issues arising in the implementation of autonomic managers taking care of multiple concerns and of coordination among ...
