== 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 webjournal |urlauthor=https://www.semanticscholar.org/paper/Doing-More-with-the-Dew:-A-New-Approach-to-David Edward Fisher- |author2=Shuhui Yang/693e467a3b5efd3ae578687fa7af3e5e57deca00 |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 |s2cid=13147444 |url=https://www.ronpub.com/OJCC/OJCC_2016v3i1n02_Fisher.html |archive-date=2023-07-02 Scholar|access-date=20182023-0607-3002 |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 web |urlauthor=https://www.semanticscholar.org/paper/Cloud-dew-architecture-:-realizing-the-potential-of-Yingwei Wang- |author2=Yi Pan/fc8edd29f5df60244a66d05c74c50a240a4529ef |title=Cloud-dew architecture : realizing the potential of distributed database systems in unreliable networks -|website=Worldcomp SemanticProceedings |s2cid=32263118 |url=http://worldcomp-proceedings.com/proc/p2015/PDP2675.pdf Scholar|access-date=20182023-0607-3002 |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>

== Possible challenges ==

Dew computing faces a number of technical challenges, including issues related to power management, processor utility, and data storage. Other factors impacting the use of dew computing are the viability of the operation system, network model, communication model, programming principles, dew recommended engine, local dew network, personal high productivity, database security, and behaviors of the browser.<ref name=":3">{{Cite journal|title=An Introduction to Dew Computing: Definition, Concept and Implications - IEEE Journals & Magazine|journal=IEEE Access|volume=6|pages=723–737|doi=10.1109/ACCESS.2017.2775042|year=2018|last1=Ray|first1=Partha Pratim|doi-access=free}}</ref>
