Dew computing

Dew computing is an information technology (IT) paradigm that combines the core concept of cloud computing with the capabilities of end devices (personal computers, mobile phones, etc.). It is used to enhance the experience for the end user in comparison to only using cloud computing. Dew computing attempts to solve major problems related to cloud computing technology, such as reliance on internet access. Dropbox is an example of the dew computing paradigm, as it provides access to the files and folders in the cloud in addition to keeping copies on local devices. This allows the user to access files during times without an internet connection; when a connection is established again, files and folders are synchronized back to the cloud server. 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 as a possible solution to the offline data accessibility problem. At first, its scope included only web applications; broader applications were later proposed. 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. 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 servers is lost, the user is unable to access their data; dew computing aims to solve this problem. As an information technology paradigm, dew computing seeks to use the capabilities of personal computers along with cloud services in a more reliable manner. The key features of dew computing are independence and collaboration. Independence means that the local device must be able to provide service without a continuous connection to the Internet.
