== History ==

While [[cloud computing]] has been expanding rapidly, other models based on cloud computing have emerged, including [[fog computing]], [[Edge computing]], dew computing, etc. Proponents claim these novel models can provide better experiences for users.<ref name=":5">{{Cite web|url=https://www.semanticscholar.org/paper/Doing-More-with-the-Dew:-A-New-Approach-to-Fisher-Yang/693e467a3b5efd3ae578687fa7af3e5e57deca00|title=Doing More with the Dew: A New Approach to Cloud-Dew Architecture - Semantic Scholar|access-date=2018-06-30}}</ref>

Cloud computing provides universal access and [[scalability]]. However, the challenges related to having all the resources far from a user's control occasionally cause 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">{{Cite journal|last=Wang|first=Yingwei|date=2016|title=Definition and Categorization of Dew Computing|url=https://www.ronpub.com/publications/ojcc/OJCC_2016v3i1n02_YingweiWang.html|journal=Open Journal of Cloud Computing|volume=3|issue=1|issn=2199-1987}}</ref><ref name=":6">{{Cite web|url=https://www.semanticscholar.org/paper/Cloud-dew-architecture-:-realizing-the-potential-of-Wang-Pan/fc8edd29f5df60244a66d05c74c50a240a4529ef|title=Cloud-dew architecture : realizing the potential of distributed database systems in unreliable networks - Semantic Scholar|access-date=2018-06-30}}</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}}</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>

The term "dew computing," as used in information technology, first appeared in 2015 in IT literature and from then on has been a field of interest. The cloud-dew architecture was proposed 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}}</ref>

== Definition ==

As an information technology paradigm, dew computing, using the core concept of cloud computing, seeks to use the capabilities of [[personal computer]]s along with [[cloud services]] in a more reliable manner.<ref name=":2">{{Cite book|title=Intelligent Communication and Computational Technologies|date=2018|isbn=978-981-10-5522-5|editor-last=Hu|editor-first=Yu-Chen|series=Lecture Notes in Networks and Systems|volume=19|doi=10.1007/978-981-10-5523-2|issn=2367-3370|editor2-last=Tiwari|editor2-first=Shailesh|editor3-last=Mishra|editor3-first=Krishn K.|editor4-last=Trivedi|editor4-first=Munesh C.}}</ref><ref name=":6" /><ref name=":5" />

The key features of dew computing are independence and collaboration. Independence means that the local device must be able to provide service without continuous connection to the [[Internet]]. Collaboration means that the application must be able to connect to the cloud service and synchronize data when appropriate.<ref name=":4" />
