The advent of both Cloud computing and Internet of Things (IoT) is changing the way of conceiving information and communication systems. Generally, we talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart devices interconnected with a remote Cloud infrastructure, platform, or software through the Internet and able to provide IoT as a Service (IoTaaS).\ In this paper, we discuss the near future evolution of IoT Clouds towards federated ecosystems, where IoT providers cooperate to offer more flexible services.\ Moreover, we present a general three-layer IoT Cloud Federation architecture, highlighting new business opportunities and challenges.\

The advent of both Cloud computing and Internet of Things (IoT) is changing the way of conceiving information and communication systems. Generally, we talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart objects, e.g., single board computers running Linux-based operating systems, interconnected with a remote Cloud infrastructure, platform, or software through the Internet and able to provide IoT as a Service (IoTaaS). In this context, container-based virtualization is a lightweight alternative to the hypervisor-based approach that can be adopted on smart objects, for enhancing the IoT Cloud service provisioning.\ 
In particular, considering different IoT application scenarios, container-based virtualization allows IoT Cloud providers to deploy and customize in a flexible fashion pieces of software on smart objects. In this paper, we explore the container-based virtualization on smart objects in the perspective of a IoT Cloud scenarios analyzing its advantages and performances.

Nowadays, the Open Archive Information System (OAIS) model is widely adopted in hospitals to manage data related to both doctors and patients. However, the Archival Storage systems of hospitals are typically based on old Relational DBMS that makes hard the management of patients{\textquoteright} data especially in HL7 format. In fact, data have to be continuously parsed in order to be stored in relational \ databases and sent to other hospital systems. Considering also interoperable scenarios where HL7 data continuously grow, the management of patients{\textquoteright} information can become very hard. In this paper, we discuss an OAIS system able to manage HL7 Big Data. In particular, considering a case of study of HL7 glucose observations in JSON format, we demonstrate that in a \ scalable scenario an archival storage for big data processing is more convenient for hospitals than traditional archival storage systems.

Nowadays, in the Cloud computing panorama, users access their Virtual Machines (VMs) using SSH or web-based remote desktop clients. In this context, OpenStack is one of the major open-source solutions for creating and managing Infrastructure as a Service (IaaS) Cloud providers. Typically, OpenStack tenants graphically control their VMs using noVNC, i.e., the default web-based remote desktop client integrated in its web dashboard. Unfortunately, up to now, considering noVNC, the video update response time is not so good and the audio redirection has not been supported yet. In this paper, we discuss how can be possible to improve the Desktop as a Service (DaaS) in OpenStack Clouds by integrating alternative solutions based on both the Remote Frame Buffer (RFB) protocol and the Remote Desktop Protocol (RDP). Experiments highlight, from an objective point of view, the behaviour of different solutions, providing useful hints to software architects and developers.

Cloud federation offers new business models to enforce more flexible energy management strategies. Typically, an independent Cloud provider is exclusively bounded to the specific energy supplier powering its data center. The situation radically change if we consider a federation of cooperating Cloud providers. In such a context a proper migration of virtual machines among providers can lead to global energy sustainability and cost-saving strategies.\ 
In this paper, we discuss a decision algorithm, for Cloud federation brokerage, able to combine these two strategies. More specifically, we present a Multi-Criteria Decision Making (MCDM) algorithm able to discover the most convenient Cloud provider candidates to join a particular energy-aware federation. In the end, by modelling different possible real Cloud providers, we demonstrate how the algorithm can accommodate different Cloud federation scenarios characterized by particular energy-aware parameters.

Nowadays, the combination between Cloud computing and Internet of Things (IoT) is pursuing new levels of efficiency in delivering services, representing a tempting business opportunity for IT operators of increasing their revenues. However, security is considered as one of the major factors that slows down the rapid and large scale adoption and deployment of both the IoT and Cloud computing. In this paper, considering such an IoT Cloud scenario, we present an architectural model and several use cases that allow different types of users to access IoT devices.

In this paper we investigate the applicability of the federation among several Cloud platform, demonstrating that a federated environment provides evident benefits despite the costs for the setup and maintainance of the federation itself. Also, we propose a new solution able to manage resource allocation in federated Clouds where resource requests occur in a dynamic way. We adopt such a solution to setup distributed Hadoop nodes of virtual clusters for the parallel MapReduce processing of large data sets. To increase their capabilities, Cloud Providers establish a federation relationship, making the Hadoop-based Cloud platforms much more performing than in the isolate case, adding a further level of parallelization in service provisioning. The results analyzed in the referece use case, that is a video transcoding using the MapReduce paradigm in a federated fashion, show how the federation costs in terms of delays and overhead are low in comparison with the service provisioning costs, and also highlight how federation makes the offered Cloud service more streamlined and fast.

The massive use of mobile devices and social networks is causing the birth of a new compulsive users{\textquoteright} behaviour. The activity photo selfie sharing is gradually turning into video selfie. These videos will be transcoded into multiple formats to support different visualization mode. We think there will be the need to have systems that can support, in a fast, efficient and scalable way, the millions of requests for video sharing and viewing. We think that a single Cloud Computing services provider cannot alone cope with this huge amount of incoming data (Big Data), so in this paper we propose a Cloud Federation-based system that exploiting the Hadoop MapReduce paradigm performs the video transcoding in multiple format and its distribution in a fastest and most efficient possible way. Experimental results highlight the major factors involved for job deployment in a federated Cloud environment and the efficiency of the proposed system.

Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at university, in an Internet point). In this paper, we discuss how cloud computing provides a valid technological solution to enhance such a scenario.With the emergence of cloud computing, many applications are executed on top of virtual machines (VMs). Virtualization allows us to achieve a software implementation of a real computer able to execute a standard operating system and any kind of application. In this paper we propose to build personalized VMs running AT programs and settings. By using the remote desktop technology, our solution enables users to control their customized virtual desktop environment by means of an HTML5-based web interface running on any computer equipped with a browser, whenever they are.

Cloud computing is rapidly evolving due to social and cultural influences that are changing the necessary Cloud services. Indeed, an increasing number of application and service providers use Cloud computing to adapt their products to customer needs, by addressing the requirements arisen by the customer Quality of Experience (QoE, QoX or simply QX) evaluation. QoE is a fast emerging multidisciplinary field based on social psychology, cognitive science, management, and engineering science, focused on understanding overall human quality requirements. In order to help Digital Business architects to understand how Cloud computing can help them to increase their business, we present a scientometric analysis of Cloud computing and QoE. Analyzing the current state of the art, we provide some guidelines to Digital Business companies for addressing the issues related to QoE that have to be taken into account in order to maximize their business.

The advent of both Cloud computing and Internet of Things (IoT) is changing the way to conceive distributed systems. Nowadays, we can talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart IoT devices or sensors interconnected with a remote Cloud infrastructure, platform, or software. Energy sustainability in IoT Cloud providers offers new tempting business opportunities for organizations, but at the same time it raises new challenges. In this paper, a flexible IoT Cloud federation energy management strategy is presented for optimizing the allocation of geographically localized smart sensors. We define the concept of IoT Cloud Federation as a mesh of IoT Cloud providers that are interconnected to provide a universal decentralized sensing and actuating environment where everything is driven by constraints and agreements in a ubiquitous infrastructure.\ In particular, a dynamic algorithm able to improve energy sustainability in a federated IoT Cloud ecosystem is discussed. In addition, we analyze a use-case driven strategy that allows both IoT Cloud providers and brokers to determine the paths to reach possible destination IoT devices in which computational resources should be dynamically migrated in order to push down the energy consumption due to IoT distributed applications.

Nowadays, the increasing interest in Cloud computing is motivated by the possibility to promote a new economy of scale in different contexts. In addition, the emerging concept of Cloud federation allows providers to optimize the utilization of their resources establishing business partnerships. In this scenario, the massive exploitation of {\.I}CT\ solutions is increasing the energy consumption of providers, thus many researchers are currently investigating new energy management strategies. Nevertheless, balancing Quality of Service (QoS) with both energy sustainability and cost saving concepts is not trivial at all. The growing interest in this area has been highlighted by the increasing number of contributions that are appearing in literature. Currently, most of energy management strategies are specifically focused on independent Cloud providers, others are beginning to look at Cloud federation. In this paper, we present a survey that helps researchers to identify the future trends of energy management in Cloud federation. In particular, we select the major contributions dealing with energy sustainability and cost-saving strategies aimed at Cloud computing and federation and we present a taxonomy useful to analyse the current state-of-the-art.

This paper deals with the automatic configuration\ of IoT devices in a secure way through the Cloud, in order\ to provide new added-value services. After a discussion on the\ limits of current IoT and Cloud solutions in terms of secure selfconfiguration,\ we present a Cloud-based architecture that allows\ IoT devices to interact with several federated Cloud providers.\ In particular, we present two possible scenarios, i.e., single Cloud\ and a federated Cloud environments interacting with IoT devices\ and we address specific issues of both. Moreover, we present\ several design highlights on how to operate considering real open\ hardware and software products already available in the market.

The transition to cloud computing offers a large number of benefits, such as lower capital costs and a highly agile environment. Yet, the development of software engineering practices has not kept pace with this change. Moreover, the design and runtime behavior of cloud based services and the underlying cloud infrastructure are largely decoupled from one another.This paper describes the innovative concepts being developed by CloudWave to utilize the principles of DevOps to create an execution analytics cloud infrastructure where, through the use of programmable monitoring and online data abstraction, much more relevant information for the optimization of the ecosystem is obtained. Required optimizations are subsequently negotiated between the applications and the cloud infrastructure to obtain coordinated adaption of the ecosystem. Additionally, the project is developing the technology for a Feedback Driven Development Standard Development Kit which will utilize the data gathered through execution analytics to supply developers with a powerful mechanism to shorten application development cycles. {\textcopyright} 2014 IEEE.

The Future Internet is required to be fast, flexible and ever-responsive to demands from both humans and machines. It is evolving as an Internet of services, things, and infrastructure and the European Commission is supporting research projects that are contributing to its evolution. Among the others, VISION Cloud and Cloudwave are two interesting examples of how data can be managed in an effective way and how applications can adapt to the infrastructure, and the infrastructure to the services requested, in order to improve the overall quality of the service provided. From our experience in these two successful projects, we show in this paper how they try to address the challenges described above, providing an important boost to making the Future Internet vision concrete. {\textcopyright} 2014 IEEE.

Nowadays, Assistive Technology (AT) systems are\ closely tied to the devices that they control. Considering a smart
environment where a person with a disability needs to interact\ with multiple devices, the user is forced to rely on AT software
tools available on the each used platform. Therefore, computer\ skills are required to adjust any different computing environment
configuration according to the user{\textquoteright}s needs and preferences.\ To address such issues, in this paper, we discuss the usage of
embedded systems able to interface sensors and existing AT\ software tools running on user{\textquoteright}s personal equipments, in order
to natively interact with many platforms. Thus, our work aims to\ decouple AT software tools from the accessed computer systems,
allowing us to control various kinds of computer systems, even\ those that do not provide any AT features, by using just a\ personal assistive equipment.

Currently, storage services represent a new way to do business in Cloud computing. This new trend is proved by the number of Cloud storage providers that are appearing on the market. In this work, we present an innovative approach useful for using different Cloud storage providers in a transparent way, avoiding both data lock-in and possible data privacy violation that can be caused by providers themselves. More specifically, we propose an approach enabling Cloud customers to rely on many Cloud storage providers. Differently from other solutions, with our approach only the customers have the full control of their data, and in addition, if a provider suddenly disappears and/or it is not available anymore, the customers will be able to continue accessing their data, reconstructing them from data fragments replicated in other Cloud storage providers. The paper shows how such an approach works. In particular, experiments, besides proving the goodness of our approach, also provide several guidelines regarding how to properly configure software systems in order to meet the customer{\textquoteright}s requirements (in terms of both QoS and costs).

This paper investigates how Cloud computing can meet the demands of people with disabilities who occasionally use a shared computer. In this situation, customized assistive software can not be available to the user since security policies prevent from having enough privileges to change local system preferences. In order to address such issue, we discuss an open source software architecture combining a web-based remote desktop management solution with virtualization technology. This system allows disabled users to access a virtual desktop running personal assistive software solutions. Hence, the disabled user can interact with the same virtual environment from any networked physical computer via a standard web browser. In the end, we discuss the major technological issue for the achievement of such a scenario.

Transportation of Dangerous Goods represents a sensitive problem due its congenital high potential risk of causing disaster if an accident occurs. Transportation of Dangerous Goods Risk Management systems reduce the possibility of both accidental disasters and terrorist attacks detecting unusual events and blocking possible threats. Cloud computing can facilitate the development of such kinds of systems thanks to new emerging paradigms and technologies. In this paper, we discuss the design of a new Message-Oriented Cloud Middleware for Cloud, that can be used to develop a Cloud-based Transportation of Dangerous Goods Risk Management system. More specifically, we investigate issues on transportation of Dangerous Goods, in order to focus the attention on the requirements of the Risk Management system. Then, we describe how to use the Message-Oriented Cloud Middleware for Cloud architecture and the necessary utilities in particular here for supporting Transportation of Dangerous Goods.

Cloud federation is paving the way toward new business scenarios in which it is possible to enforce more flexible energy management strategies than in the past. Considering independent cloud providers, each one is exclusively bound to the specific energy supplier powering its datacenter. The situation radically changes if we consider a federation of cloud providers powered by both a conventional energy supplier and a renewable energy generator. In such a context, the opportune relocation of computational workload among providers can lead to a global energy sustainability policy for the whole federation. In this work, the authors investigate the advantages and issues for the achievement of such a sustainable environment.

The right setup of a testbed is important for enabling the rapid development and deployment of cloud services, in particular all the times the testbed hosts more concurrent interactions. This work shows how to configure an environment where more developers insist on it. In particular what tools are indispensable for managing compelling distributed cloud environments. We looked at mature Open Source solutions, performing their smoothed integration. The paper describes all parts necessary for accomplishing complex scenarios, even in a bounded perimeter as the VISION Cloud EU project offering.

Cloud platforms are dynamic, self-optimizing, continuously changing environments where resources can be composed with other ones in order to provide many types of services to their users, e.g., companies, governments, organizations, and desktop/mobile clients. In order to enable cloud platforms to manage and control their assets, they need to name, identify, and resolve their virtual resources in different operating contexts. In such a scenario, naming, resource location, and information retrieval raise several issues regarding name space management. This paper aims to propose a standard practice for the implementation of a cloud naming system based on the eXtensible Resource Identifier (XRI) technology. More specifically, by means of the development of a Cloud Name Space Management (CNSM) front-end interacting with the OpenXRI architecture, we investigate its performance simulating typical cloud name space management tasks.

Nowadays, new and sophisticated technologies are quickly developing, taking advantage of the growing necessity of the companies to reduce operating costs, administrative time and to improve their productivity. Automatic Vehicle Monitoring (AVM)\ systems\ are one of the promising application fields where mobile technologies can be successfully adopted with specific care toward the definition of new\ services\ in the PTS (Public Transport\ Service) area.. The ability of an AVM\ system\ to control the street traffic represents a very important value for an advanced\ fleet\ management\ system. This paper proposes an AVM software platform, which is characterized by some innovative features able to manage multiple heterogeneous devices for\ fleet\ management\ and to monitor the street traffic.
