A manifesto for future generation cloud computing: research directions for the next decade
The Cloud computing paradigm has revolutionised the computer science horizon during the past decade and has enabled the emergence of computing as the fifth utility. It has captured significant attention of academia, industries, and government bodies. Now, it has emerged as the backbone of modern economy by offering subscription-based services anytime, anywhere following a pay-as-you-go model. This has instigated (1) shorter establishment times for start-ups, (2) creation of scalable global enterprise applications, (3) better cost-to-value associativity for scientific and high performance computing applications, and (4) different invocation/execution models for pervasive and ubiquitous applications. The recent technological developments and paradigms such as serverless computing, software-defined networking, Internet of Things, and processing at network edge are creating new opportunities for Cloud computing. However, they are also posing several new challenges and creating the need for new approaches and research strategies, as well as the re-evaluation of the models that were developed to address issues such as scalability, elasticity, reliability, security, sustainability, and application models. The proposed manifesto addresses them by identifying the major open challenges in Cloud computing, emerging trends, and impact areas. It then offers research directions for the next decade, thus helping in the realisation of Future Generation Cloud Computing
Demystifying COVID-19 digital contact tracing: A survey on frameworks and mobile apps
The coronavirus pandemic is a new reality and it severely affects the modus
vivendi of the international community. In this context, governments are
rushing to devise or embrace novel surveillance mechanisms and monitoring
systems to fight the outbreak. The development of digital tracing apps, which
among others are aimed at automatising and globalising the prompt alerting of
individuals at risk in a privacy-preserving manner is a prominent example of
this ongoing effort. Very promptly, a number of digital contact tracing
architectures has been sprouted, followed by relevant app implementations
adopted by governments worldwide. Bluetooth, and specifically its Low Energy
(BLE) power-conserving variant has emerged as the most promising short-range
wireless network technology to implement the contact tracing service. This work
offers the first to our knowledge, full-fledged review of the most concrete
contact tracing architectures proposed so far in a global scale. This endeavour
does not only embrace the diverse types of architectures and systems, namely
centralised, decentralised, or hybrid, but it equally addresses the client
side, i.e., the apps that have been already deployed in Europe by each country.
There is also a full-spectrum adversary model section, which does not only
amalgamate the previous work in the topic, but also brings new insights and
angles to contemplate upon.Comment: 34 pages, 3 figure

Learning in an age of digital networks
The final years of the twentieth century and early years of the twenty first century have been marked by the rapid rise of digital and networked technologies. Some have even called it a paradigm shift and suggested that it will lead to a dramatic change in the way young people learn (Tapscott and Williams, 2010). As with all commentary on new technologies we should beware of being carried away with the excitement of the new. There is a recurrent innovation cycle beginning with over excitement followed by disappointment and once the reaction has set in against the new it is followed by a move away to yet another new technology, often before a proper assessment and evaluation of the previous cycle can take place. Equally we must be careful not to ignore the profound changes that are taking place and how they may affect universities and learning in society more generally. A recent description by a UK based think tank Demos characterized the kind of university that is emerging from the engagement with new digital and networked technologies as the 'edgeless university' (Bradwell, 2009). The term edgeless is borrowed from work on the city that suggests edgeless cities have the function of cities without being organized in their classic form. In the same way the Demos pamphlet suggests that the university retains an identifiable function but the functions of the university are no longer confined to a single institution nor are they confined to higher education institutions more broadly. Over a decade ago Brown and Duguid (2000) identified the core functions of universities as the capacity to grant degrees, to accredit students and to provide the warrant that guaranteed the credentials obtained by the students from the university. They also suggested that the introduction of what were then new technologies would lead to an increased focus on these core functions. The core role remains in the edgeless university but the boundaries to these may alter. This article tries to provide a way of thinking about new technologies that manages to balance these two conflicting needs. It identifies some current ways of thinking about the changes taking place in universities that are related to digital and networked technologies and to assess their impact. It then goes on to suggest the kinds of choices we may have to make in relation to new technologies at a variety of levels, the personal, the institutional and in terms of society in general. The edgeless university is associated with broad technological change but whether such change is inevitable is still an issue that needs to be discussed
Building the Future Internet through FIRE
The Internet as we know it today is the result of a continuous activity for improving network communications, end user services, computational processes and also information technology infrastructures. The Internet has become a critical infrastructure for the human-being by offering complex networking services and end-user applications that all together have transformed all aspects, mainly economical, of our lives. Recently, with the advent of new paradigms and the progress in wireless technology, sensor networks and information systems and also the inexorable shift towards everything connected paradigm, first as known as the Internet of Things and lately envisioning into the Internet of Everything, a data-driven society has been created. In a data-driven society, productivity, knowledge, and experience are dependent on increasingly open, dynamic, interdependent and complex Internet services. The challenge for the Internet of the Future design is to build robust enabling technologies, implement and deploy adaptive systems, to create business opportunities considering increasing uncertainties and emergent systemic behaviors where humans and machines seamlessly cooperate
e-Skills: The International dimension and the Impact of Globalisation - Final Report 2014
In today’s increasingly knowledge-based economies, new information and communication technologies are a key engine for growth fuelled by the innovative ideas of highly - skilled workers. However, obtaining adequate quantities of employees
with the necessary e-skills is a challenge. This is a growing
international problem with many countries having an insufficient numbers of workers with the right e-Skills.
For example:
Australia: “Even though there’s 10,000 jobs a year created in IT, there are only 4500 students studying IT at university, and not all of them graduate” (Talevski and Osman, 2013).
Brazil: “Brazil’s ICT sector requires about 78,000 [new] people by 2014. But, according to Brasscom, there are only 33,000 youths studying ICT related courses in the country” (Ammachchi, 2012).
Canada: “It is widely acknowledged that it is becoming inc
reasingly difficult to recruit for a variety of critical ICT occupations
–from entry level to seasoned” (Ticoll and Nordicity, 2012).
Europe: It is estimated that there will be an e-skills gap within Europe of up to 900,000 (main forecast scenario) ICT pr
actitioners by 2020” (Empirica, 2014).
Japan: It is reported that 80% of IT and user companies report an e-skills shortage (IPA, IT HR White Paper, 2013)
United States: “Unlike the fiscal cliff where we are still peering over the edge, we careened over the “IT Skills Cliff” some years ago as our economy digitalized, mobilized and further “technologized”, and our IT skilled labour supply failed to keep up” (Miano, 2013)
