Abstract
Digital Storytelling has become a powerful instructional tool for both students and teachers, especially in an e-learning environment. This article presents an overview of Digital Storytelling - the combination of narrative with digital media – and its relation to e-learning. Digital storytelling is a process that blends traditional storytelling with the technologies and media of the digital age-images, video, audio and personal narrative.
Keywords

Abstract
In this article we will present some very important points when choosing to use a CMS to develop a digital product. The idea of this study is not to convince never to use a CMS, but to show some important points that can change the opinion of those who want to use such a tool in the digital world. We will address some positives and negatives points and then look closer from a professional perspective.

DOI: 10.31112/kriativ-tech-2018-01-28
Abstract
The Network Functions Virtualization (NFV) enables the emulation of Virtual Network Functions (VNFs) through SW configured over physical and sharable resources of generic HW, referred as COTS (Commercial off-the-shelf). Therefore, NFV replaces the traditional concept of network services implemented on dedicated HW and came to allow not only significant reductions in equipments acquisition (CAPEX) and operational costs (OPEX), but also to enable a bigger agility and speed in the development and management of network services composed by VNFs.

Abstract
The rapid growth of Cloud Based solutions creates a new paradigm that at same time raises and addresses many of the computer data security problems and challenges. On one side moving to Cloud can address some actual weaknesses and gaps of the enterprise security infrastructure and procedures but on the other side there is a new world of issues that must be addressed when moving infrastructure to a shared third-party provider. This paper will address some of these general drivers and concerns.

Abstract
The evolution of technologies such as the Internet of Things (IoT), wearables and big data, plus the increase in the use of mobile devices have required greater performance of the internet.
The web connection, however, has not yet reached its full potential, but it tends to get faster and faster to meet these new demands that have been emerging over the years.
Broadband 5G will be on the market in the next three years, will be more stable and will have sufficient capacity to meet the needs of mobile users. With the fifth generation of wireless technology it will be possible to download full movies in a matter of seconds, achieve the evolution of the Internet of Things and create intelligent and interconnected cities.

Abstract
The paradigm of cloud computing has emerged as a promising solution. It transparently provides computing, storage and communication resources, offered as an "elastic" pay-per-use service. This article analyses the evolution of Radio Access Networks (RANs), highlighting how current challenges and requirements for these networks as well as the available technology solutions drive the evolution of these networks towards the cloud. The Cloud-RAN architecture emerges as a solution that takes advantage of the characteristics of the cloud, adapting computation, radio and network resources in an elastic way, depending on the needs. This architecture is expected to reduce up to 15% of mobile operators’ acquisition costs and 50% of operating costs. The creation of an infrastructure is 3 times faster and will save up to 71% of energy compared to a traditional system.

Abstract
That the Internet and technological developments are causing changes in societies, industry and education, particularly in distance education, are undeniable facts. Access to information is facilitated, but the difficulty in perceiving what is reliable also increases. Through the development of a Massive Open Online Course, this article seeks to identify the impact of this type of training on Education Institutions and their Participants, knowing that the educational contents will have the scientific guarantee of the provider institution. In this sense, a course developed at the Polytechnic Institute of Santarém with participants from various locations around the globe is presented, from its development process to the results of participation, culminating in a reflection on its impacts.
Keywords
