Abstract :
Over the last decades, the IT world has witnessed paradigm shifts from conventional client/server networks to Cloud computing, providing organizations opportunities to reduce capital expenditures (CapEx) and Operational Expenditures (OpEx). Other technologies such as Fog computing, Edge computing addresses some of Cloud computing challenges such as high latency, real-time process, security, and location awareness. Unfortunately, all technologies mentioned above are prone to service outages and interruption due to their dependency on the Internet. Dew computing filled the gaps by providing users with offline usage capabilities. During outages or service interruptions, Dew computing makes data accessibilities archivable through two distinct features interdependency and collaboration. Copies of original data saved on the local machine are available to serve offline requests, and all modifications synchronize with the Cloud server when the communication signal is restored. This paper explains the Dew computing concepts, architectural design, and open research opportunities.
