  Edge Computing is a new distributed Cloud Computing paradigm in which
computing and storage capabilities are pushed to the topological edge of a
network. However, various standards and implementations are promoted by
different initiatives. Lead by a reference architecture model for Edge
Computing, current initiatives are analyzed by explorative content analysis.
Providing two main contributions to the field, we present, first, how current
initiatives are characterized, and second, a roadmap for sustainable Edge
Computing relating three dimensions of sustainable development to four
cross-concerns of Edge Computing. Findings show that most initiatives are
internationally organized software development projects; important branches are
currently telecom and industrial sectors; most addressed is the network
virtualization layer. The roadmap reveals numerous chances and risks of Edge
Computing related to sustainable development; such as the use of renewable
energies, biases, new business models, increase and decrease of energy
consumption, responsiveness, monitoring and traceability.
