    O conceito de Cloud Computing tem sido amplamente discutido sendo uma vertente desta abordagem a redu√ß√£o dos custos. S√£o diversos os prestadores de servi√ßos de Cloud existentes no mercado e diversificados os modelos de servi√ßos que estes disponibilizam atrav√©s da internet. √Č objetivo deste artigo apresentar uma breve caracteriza√ß√£o do estado da arte no que se refere a esta tem√°tica bem como suportar o seu conte√ļdo num estudo efetuado numa Organiza√ß√£o de m√©dia dimens√£o. Foram abordadas duas perspectivas nesse estudo: utiliza√ß√£o de servi√ßos de gest√£o e arquivo do correio eletr√≥nico em infraestrutura do fornecedor (Public Cloud), e virtualiza√ß√£o de ambiente de trabalho desktop, em servidores de data-center interno (Private Cloud). Foi poss√≠vel concluir que cada fornecedor adequa os modelos de neg√≥cio √† sua especialidade, originando um mercado heterog√©neo e de dif√≠cil an√°lise comparativa dos servi√ßos disponibilizados. Considera-se que ser√° premente a conce√ß√£o de prot√≥tipos que avaliem em contexto organizacional a viabilidade das solu√ß√Ķes a implementar.The concept of Cloud Computing has been discussed largely by cost reduction. There are several Cloud providers in the market with diversified models of services accessed over the internet. The purpose of this paper is to present the state of the art with regard to this issue and frame a study conducted in a medium-sized organization. Two perspectives were addressed in this study: use of electronic mail management services in the provider's infrastructure (Public Cloud), and desktop virtualization desktop in internal datacenter (Private Cloud). It was concluded that vendors are making the business models according to their specialty, resulting in a very heterogeneous market and a difficult benchmarking analysis of the services offered, pointing to the need for prototyping tested in the field to assess the feasibility of the solutions

    Recentemente, a ind√ļstria de desenvolvimento de programas inform√°ticos de fatura√ß√£o foi incentivada a incluir novas val√™ncias veiculadas por altera√ß√Ķes legislativas fiscais. Neste sentido, foi efetuado o enquadramento fiscal, a caracteriza√ß√£o das empresas e da fatura√ß√£o em Portugal, por meio de programa inform√°tico de fatura√ß√£o certificado. O valor acrescentado, centrou-se na an√°lise das condicionantes impl√≠citas ao processo de certifica√ß√£o, pela Autoridade Tribut√°ria e Aduaneira, no sentido de otimizar a perce√ß√£o que as organiza√ß√Ķes t√™m deste processo. Considera-se assim, que est√£o criadas condi√ß√Ķes que potenciam a otimiza√ß√£o do processo de certifica√ß√£o, no sentido de contribuir para o aumento do n√ļmero de programas certificados.Recently, the invoicingsoftware development industry has been challenged to include new requirementsconveyed by tax legislative changes. Withthis in mind, it was identified the applicable tax framework, the characterization of companies and invoicing in Portugal,through a certified invoicing software. The added value was centered on the analysis of the implicit constraints to the certification process, by the Tax and Customs Authority, in order to optimize the perception that organizations have of this process. Thus, it is considered that conditions are created that enhance the optimization of the certification process, in order to contribute to the increase in the number of certified programs.info:eu-repo/semantics/publishedVersio

    Get PDF
    The Public Administration (PA) in Portugal is impacted by the constant acceleration and evolution of Information and Communication Technologies (ICT), where the Portuguese State, transposing European Union directives, has legislated and encouraged their use as instruments of added value for the PA. Establishing rigorous and sustainable governance is crucial, ensuring that the organization’s strategic objectives are aligned with ICT and, preferably, with Green IT practices. In this context, it is necessary to be able to estimate and subsequently evaluate the impact of strategic and operational choices on improving environmental quality. For such, this article presents a framework developed to optimize ICT management practices and indicators that, in this environmental area, support the forecasting and assessment of the impact of the choices made in the search for technologically advanced solutions in the Barreiro municipality. These choices enable, among other things, a reduction in energy consumption, implying a reduction in financial costs, resulting in environmental benefits, such as a reduction in CO2 emissions into the atmosphere or less deforestation. The results presented, obtained in a real-world context, make it possible to assess the progress of alignment with Green IT in this area, as well as the overall result.info:eu-repo/semantics/publishedVersio

    Get PDF
    In a world where sustainability is increasingly important, we must look for ways to promote it; the Sustainable Development Goals (SDGs) fulfill this function. In software engineering, one of the main challenges for the success of a software solution is to achieve sustainability. This chapter introduces the development of two mobile applications on Android: Diabetes Tracker and Volunteer+ that are inspired by the SDGs, incorporating the principles and dimensions of the Karlskrona Manifesto in relation to the software development phases. In this investigation, a customized adaptation of the Scrum agile methodology was used, with a concern to promote software engineering for sustainability. To achieve this end, an iterative approach is used, allowing the principles of the manifesto to be crossed to emphasize the various dimensions of sustainability. The main results can be seen in the applications developed, specifically to facilitate the control of the diabetes disease and promote quality health, as well as enhance the participation of citizens by promoting volunteering

    Get PDF
    In the current global context, with so many challenges to be faced, it is important to see people’s increased interest in sustainability issues as an opportunity for change. Sustainable Software Engineering, as a recent research area, incorporates sustainability principles and dimensions in the software development process. On the other hand, the Design Science Research methodology has become a well-received research paradigm in Information Systems in general and in Software Engineering in particular. The paper presents a Sustainable Software Engineering approach integrated into the Design Science Research methodology. The concepts of sustainability in software development, namely the principles of the Karlskrona Manifesto, the principles of Green Software Engineering and the Sustainable Development Goals are integrated into the approach. Preliminary results from applying the approach indicate that the iterative process of the Design Science Research methodology allows for the integration of multidisciplinary sustainability artefacts during the software process

    Silveira, C., Santos, V., Reis, L., & Mamede, H. (2022). CRESustain: Approach to Include Sustainability and Creativity in Requirements Engineering. Journal of Engineering Research and Sciences, 1(8), 27-34. https://doi.org/10.55708/js0108004, https://doi.org/10.55708/js0108Requirements Engineering is an evolving field facing new challenges. One of the central conundrums is sustainability in software. The possibility of using known creativity techniques while introducing the dimensions of sustainability to help provide unexpected, original, practical, and sustainable answers in software development is challenging and motivating. This paper proposes an approach, CRESustain, incorporating sustainability dimensions when introducing creativity techniques in the Requirements Engineering process. CRESustain uses various creativity techniques considered appropriate for the different stages of the RE process. It is inspired by the Sustainable Development Goals, creative problem-solving methods, and the Karlskrona Manifesto. The methodology applied to give materiality to the outcome of this work was Design Science Research, a research paradigm that uses knowledge to solve problems, generate new knowledge and insights, and results in an artefact. The main results indicate that the approach stimulates discussion about sustainability in technical, economic, social, human, and environmental dimensions focusing on the Sustainable Development Goals and people's needs.publishersversionpublishe
