Conference Paper
The concept of Green Computing and, more specifically, energy-aware solutions have gained attention in the last years in many fields of ICT: network management is one of those. Today, power consumption is considered a fundamental parameter, as well as latency, bandwidth or error rate, to take into account when a new routing strategy is designed. In...
Conference Paper
In recent years, the widespread use of container technologies has significantly altered the interactions between cloud service providers and their customers when developing and offering services. The shift away from Virtual Private Server scenarios in Infrastructure-as-a-Service environments requires drastically changing the deployment strategies a...
Article
Distributed systems are dynamic systems where software and hardware together deliver information processing services to allow modelling, interaction, reasoning, analysis and control of the external environment. The intent of the distributed computation is to execute computational workflows using computing resources. The software contains the algori...
Article
In this paper, the authors introduce and describe the concept of File System as a Services (FSaaS), an highly configurable cloud service that enables cooperating, distributed applications to define their own rules and policies for managing sets of files shared. The FSaaS aims to create a logical virtual space, containing references to shared files,...
Article
Recently, the widespread adoption of ICT within the cities is significantly changing the way people work and interact with the public administrations. The idea of smart city is becoming very popular. It indicates all those cities where innovative and efficient public services and/or applications are integrated within both mid- and long-term plans o...
Conference Paper
Today, the Infrastructure as a Service (IaaS) cloud environments represent a market share on which many big economical players (Amazon, Microsoft, Rack space) are converging. The hetereogenity and the degree of customization of Cloud features and funcionalities supplied, the different pricing model adopted, the different QoS strategies proposed to...
Conference Paper
The use of virtualization technologies and the introduction of multi-core processors have strongly influenced the way of designing and developing software systems. Thus controlling and effectively managing them is became a fundamental issue, especially in distributed scenarios, as Clouds or Grids, providing QoS-assured services on demand. In this w...
Conference Paper
IaaS cloud providers, as Amazon or Rackspace, provide their users with the abilities to create an own virtual environment, populate it with their applications, and manage a wide range of critical issues (e.g. scale up/down, load balancing, faults) by means of ad hoc services. One of the limits of these cloud systems is the lack of tools that enable...
Conference Paper
Full-text available
Differently from classical JVMs, generally JavaCard Virtual Machines (JCVMs) rely only on limited amount of resources typical of smart cards. Recently, several mixes of logical and physical manoeuvres have been devised to exploit typical JCVM weaknesses and to have mutant applets by means e.g. of faults injection. Such combined attacks manage to by...
Conference Paper
The scale of the current cloud infrastructures and the heterogeneity of applications running on them pose significant challenges about resources management on clouds. This paper proposes a monitoring system that allows user to collect and aggregate data in a form flexible and adequate to the integration with the management policy that he adopt. Thi...
Conference Paper
The optimal allocation of Communication-Intensive Applications is a well-know complex issue in Clouds. This kind of applications, due to the strong impact of communications on their performance, requires not only that their tasks are allocated on resources able to satisfy their computational requirements but also that the distance among these resou...
Article
Full-text available
This paper describes a prototype implementing a high degree of transaction resilience in distributed software systems using a non-von Neumann computing model exploiting parallelism in computing nodes. The prototype incorporates fault, configuration, accounting, performance, and security (FCAPS) management using a signaling network overlay and allow...
Article
One of the most significant discussions about service-oriented architectures concerns the creation of new complex services through the composition, under Quality of Service (QoS) constraints, of simple basic services. In fact, although the composition represents a flexible and powerful strategy for the creation of new services, it raises many probl...
Article
In recent years, Grid systems and Peer to Peer networks are the most commonly-used solutions to achieve the same goal: the sharing of resources and services in heterogeneous, dynamic, distributed environments. Many studies have proposed hybrid approaches that try to conjugate the advantages of the two models. This paper proposes an architecture tha...
Conference Paper
In these years, the Grid middlewares are having a rapid evolution, a successful application and a widespread deployment, thus attracting many commercial interests. The opportunity to evolve the current implementations of Grids,presently used mainly in e-science environments, towards a services market place represents, today, one of the most importa...
Conference Paper
Provisioning specific level of QoS in a grid environment represents a central concern in obtaining a flexible and dynamic services management on large scale distributed systems. The recent orientation of grid middlewares towards the concept of trading services, wherein providers and consumers of services are able to negotiate all services parameter...
Conference Paper
In recent years, grid systems and peer to peer networks are the most used solutions to achieve the same goal: sharing resources and services in heterogeneous, dynamic, distributed environments. Grid systems have well defined middleware, able to assure trust among participants, but they are not totally scalable and they have low fault tolerance. On...
Conference Paper
Fault tolerance and scalability are two fundamental issue of discovery information protocols for wide area distributed systems. In a our previous work we have introduced a discovery protocol focused on these two requirements but, although the led tests have shown the validity of adopted solution, the protocol performance are bound by the slow updat...
Conference Paper
Ensuring that a job executes at the desired timeframe in a grid environment is possible only when reservation policies are employed. Such policies often require users to predict job needs in terms of duration and CPU capability. However the efficient use of resources can be jeopardised by the low accuracy of user predictions. This paper proposes: (...
Article
Nuclear factor-kappaB (NF-kappaB) is a transcription factor which plays a pivotal role in the induction of genes involved in physiological processes as well as in the response to injury and inflammation. Dithiocarbamates are antioxidants which are potent inhibitors of NF-kappaB. We postulated that pyrrolidine dithiocarbamate (PDTC) would attenuate...
Article
Recent studies have demonstrated that cloricromene, a coumarin derivative, exerts protective effects in models of inflammation and shock. Tumour necrosis factor plays a pivotal role in the induction of genes involved in physiological processes, as well as in the response to inflammation. We investigated the effect of cloricromene in a rat model of...
Article
The peroxisome proliferator-activated receptor-gamma (PPAR-gamma) receptor appears to play a pivotal role in the regulation of cellular proliferation and inflammation. Recent evidence also suggests that rosiglitazone, a PPAR-gamma agonist, reduces acute and chronic inflammation. We hypothesized that rosiglitazone would attenuate periodontal inflamm...
Article
Recent studies have demonstrated that Tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), a cell membrane-permeable radical scavenger, exerts protective effects in various models of inflammation and shock. Reactive oxygen species (ROS) plays a pivotal role in the induction of genes involved in physiological processes as well as in the response...
