Economics of Grids, Clouds, Systems, and Services: 18th International Conference, GECON 2021, Virtual Event, September 21–23, 2021, Proceedings (Computer Communication Networks and Telecommunications)

This book constitutes the refereed proceedings of the 18th International Conference on Economics of Grids, Clouds, Systems, and Services, GECON 2021, in September 2021. Due to COVID-19 pandemic the conference was held virtually hosted by the Libera Università Maria SS. Assunta (LUMSA), Rome, Italy. The 7 full papers and 2 short papers presented in this book were carefully reviewed and selected from 41 submissions. In addition, this book includes 8 work-in-progress papers and 2 extended abstracts. Chapters “AI Technologies and Motives for AI Adoption by Countries and Firms: A Systematic Literature Review”; “Knowledge Management Framework for Cloud Federation”; “Architecture for Orchestrating Containers in Cloud” and “Towards Software Compliance Specification and Enforcement using TOSCA” are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
