o:33374 Cloud versus Edge: Who Serves the Internet-of-Things Better? en Abstract: Usually announced to the ICT community as rivals in the Internet-of-Things (IoT) context, cloud and edge could work together according to their respective capabilities. Today’s IoT applications cannot be dependent on a single technology (either SQL or noSQL) nor a single operation model (either centralized or decentralized). The challenges are multiple including complexity of user scenarios, multiplicity of things, sensitivity of data, etc. This paper raises the question of who serves IoT better? Cloud, only; edge, only; or both together. To answer this question, clouds’ and edges’ duties are identified and then a set of collaborative scenarios are discussed with respect to these duties. Keywords: cloud computing, edge computing, internet-of-things. 1552099 10.1002/itl2.66 1552101 2476-1508 2024-04-03T11:47:09.539Z 44 no 46 Zakaria Maamar 0000-0003-4462-8337 Thar Baker person 0000-0002-5166-4873 Mohamed Sellami person 0000-0002-7547-1857 Muhammad Asim person 0000-0002-3666-1594 Emir Ugljanin Državni univerzitet u Novom Pazaru person 104999689 0000-0003-1721-3208 Noura Faci person 0000-0001-7428-6302 application/pdf 111717 https://phaidrabg.bg.ac.rs/o:33374 no yes 1 70 92000001 20A01 Internet Technology Letters 1 2018
