This book constitutes the revised selected papers of the 8th International Conference on Networked Systems, NETYS 2020, held in Marrakech, Morocco, in June 2020.* The 18 revised full papers and 4 short papers presented together with 3 invited papers were carefully reviewed and selected from 46 submissions. The papers cover all aspects related to the design and the development of these systems, including, but not restricted to, concurrent and distributed algorithms, parallel/concurrent/distributed programming, multi-core architectures, formal verification, distributed databases, cloud systems, networks, security, formal verification, etc. *The conference was held virtually due to the COVID-19 pandemic.
