Integrated Green Cloud Computing Architecture

Arbitrary usage of cloud computing, either private or public, can lead to uneconomical energy consumption in data processing, storage and communication. Hence, green cloud computing solutions aim not only to save energy but also reduce operational costs and carbon footprints on the environment. In this paper, an Integrated Green Cloud Architecture (IGCA) is proposed that comprises of a client-oriented Green Cloud Middleware to assist managers in better overseeing and configuring their overall access to cloud services in the greenest or most energy-efficient way. Decision making, whether to use local machine processing, private or public clouds, is smartly handled by the middleware using predefined system specifications such as service level agreement (SLA), Quality of service (QoS), equipment specifications and job description provided by IT department. Analytical model is used to show the feasibility to achieve efficient energy consumption while choosing between local, private and public Cloud service provider (CSP).Comment: 6 pages, International Conference on Advanced Computer Science Applications and Technologies, ACSAT 201

Smart Agriculture Development and Its Contribution to the Sustainable Digital Transformation of the Agri-Food Sector

This study analyses the importance of the connection between the development of smart agriculture and sustainable digital transformation (DT) of the agri-food sector. The sustainability of DT depends on a number of complex components, especially information and communication technologies (ICT), and economic systems. The increase in the number of studies in this area indicates a complex nature as well as interdependencies. Over the last few decades of innovation, ICT, artificial intelligence (AI) and the Internet of Things (IoT) have significantly affected human activities in all aspects. This includes the rapidly changing and difficult-to-predict agricultural sector in the context of global development, indicating the need to address these challenges. The global trend of DT has included all sectors, opening space for the contribution of smart agriculture to sustainable DT, but also to find appropriate "tailor-made solutions" for every challenge we face

The cloudification perspectives of search-based software testing

To promote and sustain the future of our society, the most critical challenge of contemporary software engineering and cloud computing experts are related to the efficient integration of emerging cloudification and DevOps practices in the development and testing processes of modern systems. In this context, we argue that SBST can play a critical role in improving testing practices and automating the verification and validation (V&V) of cloudification properties of Cloud Native Applications (CNA). Hence, in this paper, we focus on the untouched side of SBST in the cloud field, by discussing (1) the testing challenges in the cloud research field and (2) summarizing the recent contributions of SBST in supporting development practices of CNA. Finally, we discuss the emerging research topics characterizing the cloudification perspectives of SBST in the cloud field

Cloud-native databases : an application perspective

As cloud computing technologies evolve to better support hosted software applications, software development businesses are faced with a multitude of options to migrate to the cloud. A key concern is the management of data. Research on cloud-native applications has guided the construction of highly elastically scalable and resilient stateless applications, while there is no corresponding concept for cloud-native databases yet. In particular, it is not clear what the trade-offs between using self-managed database services as part of the application and provider-managed database services are. We contribute an overview about the available options, a testbed to compare the options in a systematic way, and an analysis of selected benchmark results produced during the cloud migration of a commercial document management application
