A smart contract is the formalisation of an agreement, whose terms are automatically enforced by relying on a transaction protocol, while minimising the need of intermediaries. Such contracts not only specify the service and its quality but also the possible changes at runtime of the terms of agreement. Although smart contracts provide a great deal of flexibility, analysing their compatibility and...
With the wide adoption of hybrid cloud, there are many potential risks that need to be mitigated to ensure that the utilizations of services are at their optimal levels. One of the major risks that has garnered much attention is maintaining maximum security and confidentiality for sensitive information. Detecting sensitive content at near real-time and at cloud scale has become a critical first step...
The efforts and findings of the last decades of research on the formalization and the verification of Web services have given a certain level of assurance on Web services. However new challenges such as high availability and security issues are not fully addressed. In fact, Web services are exposed to attacks that appear continuously. These issues have naturally paved the way to a new research topic...
A federated cloud environment is composed of interconnected clouds that share resources using an interface, transparent to users. In such environments, ensuring security is a complex task, since individual characteristics of each federated cloud has to be considered. This is one important issue, which can prevent companies and organizations from adopting federated clouds. In this context, this paper...
Cloud federation is receiving increasing attention due to the benefits of resilience and locality it brings to cloud providers and users. Our analysis of three diverse use cases shows that existing solutions are not addressing the federation needs of such use case applications. In this paper, we present an alternative approach to network federation, providing a model based on cloud-to-cloud agreements...
This work presents the evolution of a solution for predictive maintenance to a Big Data environment. The proposed adaptation aims for predicting failures on wind turbines using a data-driven solution deployed in the cloud and which is composed by three main modules. (i) A predictive model generator which generates predictive models for each monitored wind turbine by means of Random Forest algorithm...
In some industries, recruiting qualified resources can be a problem for SMEs, one option is to start a transformation process, and move from a traditional team to a distributed team, gaining access to a much larger base of possible human resources and business opportunities. Digital transformation can be used to help SMEs in taking the steps needed to become distributed companies. This paper shows...
Cloud Environment allows enterprises to scale their application on demand. Microservice design is a new paradigm for cloud application development which is gaining popularity due to its granular approach and loosely coupled services unlike monolithic design with single code base. Applications developed using microservice design results in better scaling and gives extended flexibility to the developers...
Cloud computing has emerged as a new computer term that relates to provide reliable computing environments, based on a better quality of service and availability of the infrastructure without a major financial burden. The cloud computing has become a very active area of research, with the emergence of business process management (BPM) in the cloud, where the adoption of BPM with Cloud Computing has...
Many problems in power distribution systems affecting today's technological equipment are often generated locally within a facility from any number of situations, such as local construction, heavy loads, faulty distribution components, and even typical background electrical noise. Penetration of advanced sensor systems such as advanced metering infrastructure (AMI), high-frequency overhead and underground...
The advances in Internet of Everything (IoE) and the market-oriented cloud computing have provided opportunities to resolve the challenges caused by the Internet of Things (IoT) infrastructure virtualization, capacity planning, data storage or complexity. The volume and types of IoT data motivate the need for a data storage framework towards the integration of both structured and unstructured data...
The evolution of the Internet has brought new ways of doing business, with more flexibility and collaboration between customers and service providers. Internet technology providers have also evolved, providing infrastructure, platforms and software as services. However, current platforms in the cloud do not offer the necessary features for each of these business models, as is the case of the freemium...
Nowadays, we can talk about the Internet of Things (IoT) and Cloud computing union to indicate a new generation of distributed system. An IoT-Cloud system mainly consists of a set of smart objects which are interconnected through the Internet with a remote Cloud infrastructure, platform, or software. It allows to achieve new benefits in several contexts, such as smart cities and industrial businesses...
As companies generate and handle increasingly large amounts of data along with the Big Data era, several model of data lifecycle have been proposed to deal with this situation. The analysis, the management and the use of data becomes more complicated or almost impossible in some cases for the companies. To transform these data to a knowledge, the choice of the adequate lifecycle that matches with...
Due to a demand for computing of huge proportions and cheap in cost, cloud computing is now a favoured model. This type of technology has been utilized by some government organizations to address the demands and requirements of their citizen. However, constraints exist with the use of this model impacting on service provision and use of this technology. This paper will explore the disparate challenges...
Construction supply chain involves a multitude of stake holders, communication between different stake holders play the major role in construction projects. Cost and time over run of projects occur due to delay in communication. Despite of being one of the oldest industries, construction industry is still fragmented. Transferring and updating of information takes place repeatedly between different...
With the data universe expanding to uncontrollable limits, we are losing control of our personal information. From online purchases to movie streaming, we are giving vendors more and more information, such that our privacy is at stake. Hackers and third-parties can gain access to this information, putting us at risk to a number of attacks. The current model where every online vendor has personal information,...
The development and maturity of the big data technology is a great opportunity for the oil and gas industry. It provides a new way to solve many problems which puzzle the oil and gas exploration. At the same time it is also a huge challenge. Petroleum exploration and development involves a wide range of fields, and it contains complex techniques. Many data of petroleum exploration and development...
Internet of Things (IoT) is overturning traditional business models. IoT and Internet of Cars compose the internet of vehicles, which is creating driverless car times. Automotive aftermarket including maintenance, washing, car care, insurance and automobile finance, represents a whopping 60% of the overall auto market. Car wash is the most frequent one of all the service items, attracting internet...
Cloud computing (CC) is a maturing concept that is changing the way information technology is deployed globally. The promotion of CC with an expected impact of transforming the competitive landscape introduced the need to make strategic decisions whether to adopt this technology or not. Organisations world-wide need to take a position amongst the maze of promises as to the benefits of cloud computing,...
