Ensuring Resource Availability with MRU/FRU Caching: A Dew-Blockcloud Model

Abstract

Combining the blockchain and cloud computing systems in different ways in order to address computing issues such as decentralization and security has slowly become a norm in recent times. These Block-Cloud model(s), which are becoming prominent in the literature seem to ensure integrity in the Cloud but lacks in exhibiting availability of resources, which is essential for security. In this study, a dew-blockcloud model is designed to address this problem. We propose a hybrid MRU/FRU caching algorithm for the dew server that reduces the number of repeated cloud accesses while maintaining relevant updated data. Using existing literature and postulation we show that dew computing might be the best availability system for the blockcloud model.
