== History ==

The term "dew computing", as used in information technology, first appeared in 2015 in IT literature and since then has become a field of its own. The cloud-dew architecture was proposed by Yingwei Wang<ref>{{Cite web |date=2015-09-17 |title=Dew Architecture helps Ground Cloud Services |url=https://www.rdworldonline.com/dew-architecture-helps-ground-cloud-services/ |access-date=2025-03-03 |website=Research & Development World |language=en-US}}</ref> as a possible solution to the offline data accessibility problem.<ref name=":7">{{Cite web|url=http://wwwen.zte.com.cn/endata/magazine/ztecommunications/2017/5/articles/201711/t20171124_466311.html|title=Dew Computing and Transition of Internet Computing Paradigms - ZTE Corporation|website=wwwen.zte.com.cn|access-date=2018-06-30|archive-date=2018-09-15|archive-url=https://web.archive.org/web/20180915122113/http://wwwen.zte.com.cn/endata/magazine/ztecommunications/2017/5/articles/201711/t20171124_466311.html|url-status=dead}}</ref> At first, its scope included only [[web application]]s; broader applications were later proposed.<ref>Skala, Karolj; Davidović, Davor; Afgan, Enis; Sović, Ivan; Šojat, Zorislav: [https://www.ronpub.com/publications/OJCC_2015v2i1n03_Skala.pdf Scalable Distributed Computing Hierarchy: Cloud, Fog and Dew Computing] // Open Journal of Cloud Computing (OJCC), 2 (2015), 1; 16-24 doi:10.19210/1002.2.1.16</ref><ref name=":1" />

Dew computing is a model which was derived from the original concept of [[cloud computing]]. Other models have also emerged from cloud computing, including [[fog computing]], [[edge computing]], dew computing, and others. Proponents claim that these novel models, such as dew computing, can provide better experiences for users.<ref name=":5">{{Cite documentjournal |author=David Edward Fisher |author2=Shuhui Yang |title=Doing More with the Dew: A New Approach to Cloud-Dew Architecture -|journal=Open SemanticJournal of Cloud Computing |volume=3 |issue=1 |pages=8–19 Scholar|s2cid=13147444 |url=https://www.ronpub.com/OJCC/OJCC_2016v3i1n02_Fisher.html |archive-date=2023-07-02 |access-date=2023-07-02 |archive-url=https://web.archive.org/web/20230702231421/https://www.ronpub.com/OJCC/OJCC_2016v3i1n02_Fisher.html |url-status=live }}</ref>

Cloud computing provides universal access and [[scalability]]. However, having all the resources far from a user's control occasionally causes problems. In the classic cloud computing paradigm, when the internet connection to the [[Server (computing)|servers]] is lost, the user is unable to access their data; dew computing aims to solve this problem.<ref name=":0" /><ref name=":6">{{Cite documentweb |author=Yingwei Wang |author2=Yi Pan |title=Cloud-dew architecture : realizing the potential of distributed database systems in unreliable networks -|website=Worldcomp SemanticProceedings Scholar|s2cid=32263118 |url=http://worldcomp-proceedings.com/proc/p2015/PDP2675.pdf |access-date=2023-07-02 |archive-date=2023-02-17 |archive-url=https://web.archive.org/web/20230217014301/http://worldcomp-proceedings.com/proc/p2015/PDP2675.pdf |url-status=live }}</ref><ref name=":1">{{Cite news|url=https://phys.org/news/2015-09-dew-ground-cloud.html|title=Dew helps ground cloud computing|access-date=2018-06-30|archive-date=2018-09-15|archive-url=https://web.archive.org/web/20180915122223/https://phys.org/news/2015-09-dew-ground-cloud.html|url-status=live}}</ref><ref name=":4">{{Cite journal|last=Yingwei|first=Wang|date=2015|title=The initial definition of dew computing|url=https://www.islandscholar.ca/islandora/object/ir:20044|journal=Dew Computing Research}}</ref>
