Fault Tolerance in Cloud and Fog Computing—A Holistic View

Abstract

Cloud computing is paramount in information technology, and cloud computing has revolutionized the traditional ways of dealing with IT resources. Fog computing can be used in both large cloud systems and big data structures which is used for solving growing difficulties in information technology. Cloud computing and fog computing are used for large amount of storage, data and applications for the end users. Compared to cloud, fog computing is near to the end users. The major difference between cloud computing and fog computing is that cloud computing is centralized system and fog computing is distributed decentralized infrastructure. Many faults occur in cloud and fog computing, and there are various methods for fault tolerant techniques.
