2nd International Workshop on Next Generation Information Systems: Emerging Challenges in Fog and Cloud Computing (NeGIS 2021)
Co-located with CAiSE'21

29th June 2021Melbourne, Australia

The amount of data and services supported by Information Systems (ISs) has increased exponentially during the last few years. To improve their efficiency and reduce costs, modern organizations have been shifting their services, with part of their ISs, to the Cloud. More recent developments have shown an inversion towards decentralization and distribution of applications and services in the huge pool of devices and computing facilities available nearer to the customers. This shift is due to the impact of the Internet of Things, which is further increasing the amount of data to be stored and computed. The next generation of Information Systems will further push these trends to create seamless and pervasive systems.  Fog Computing, in particular, is the last frontier for ISs, where data and services can be moved in the continuum of resources between the cloud and the edge.
In this context, the management of ISs can exploit the diversification of the resources available, but at the same time is getting more and more complex and challenging. The management of next-generation ISs should, therefore,  take into consideration the heterogeneity of the cloud/fog infrastructure. Such complex architecture is posing new challenges in the management of modern applications, especially in reference to enhancement of quality of service, security, privacy, and energy efficiency.  In particular, security and privacy need to be considered for the amount of sensitive data possibly produced, while energy efficiency is central, due to the high amount of computational nodes involved. Approaches such as blockchains and distributed learning can be exploited to face these emerging challenges, but universally accepted solutions for next-generation ISs are yet to be found.
In this workshop, we aim to collect contributions investigating the management of cloud and fog computing in next-generation Information Systems.

Topics include but are not limited to:
Modeling, Monitoring, and Managing Cloud and Fog computing solutions
Models, methods, and tools for data management in Cloud and Fog Computing
Energy-awareness and sustainability in Distributed Information Systems
Quality of Service, energy efficiency and security in Fog Computing
Blockchain proposals for IoT and edge devices
Blockchain-based architectures for Fog Computing
Distributed and Federated Learning in heterogeneous Information Systems
Synergy between  Distributed Information Systems and the Internet of Things
Security and privacy solutions for next-generation Information Systems.

Negis2021 will be co-located in Melbourne with the 33rd International Conference on Advanced Information Systems (CAISE'21, 28 June-2 July 2021).

The best paper will be considered for publication in the International Journal of Cooperative Information Systems (IJCIS). To be selected the paper must include a validation of the proposed approach. The authors of the paper selected as the best paper will have to provide an extended version for submission to a fast evaluation track.

Abstract submission: 22nd February 2021
Full paper submissions: 1st March 2021
Notification of acceptance: 6th April 2021
Camera-ready copies: 12th April 2021
Workshop: 29th June 2021

The workshop is addressed to researchers with a background in the field of Emerging Challenges of information systems in Cloud and Fog Computing. Contributions will be evaluated for their relevance to the workshop topics and will be blind reviewed by at least three PC members. The workshop will be divided into two main parts. In the first part, authors of accepted papers will present their work. This part will be divided into sessions according to the topics that emerged from the contributions. The second part will be a round table for discussing issues and solutions, aiming at enhancing collaboration.
Contributions are accepted in the form of:
Full Papers describe original solutions (theoretical, methodological or conceptual) in the field of sustainable IS engineering.
Short Papers describe an initial approach towards an innovative idea in the field of sustainable IS engineering.

Papers should be submitted in PDF format. The results described must be unpublished and must not be under review elsewhere. Submissions must conform to Springer’s LNBIP format and should not exceed 12 pages (6 pages for short papers), including all text, figures, references, and appendices.
Authors should consult Springer’s authors’ guidelines and use their proceedings templates, either for LaTeX or Word, for the preparation of their papers. Springer encourages authors to include their
ORCIDs in their papers. In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made.
