Abstract

Blockchain technology is a distributed ledger with records of data containing all details of the transactions carried out and distributed among the nodes present in the network. All the transactions carried out in the system are confirmed by consensus mechanisms, and the data once stored cannot be altered. Blockchain technology is the necessary technology behind Bitcoin, which is a popular digital Cryptocurrency. “Cloud computing is a practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer.” It is still facing many challenges like data security, data management, compliance, reliability. In this article, we have mentioned some of the significant challenges faced by the cloud and proposed solutions by integrating it with blockchain technology. We tend to investigate a brief survey on earlier studies focused on blockchain integrating with the cloud to depict their supremacy. In this survey, we have also developed architecture integrating blockchain with cloud revealing the communication between blockchain and cloud.

Highlights

  • Cloud computing is a well-defined technology that emerged from large-scale, distributed computing technology

  • Cloud computing is a well-known technology as it has existed for many years

  • People are still struggling to overcome some challenges of cloud computing like data security, data management, interoperability, etc

Summary

INTRODUCTION

Cloud computing is a well-defined technology that emerged from large-scale, distributed computing technology. Blockchain provides a decentralized network in which all the network nodes have active participation to validate and verify the data. Blockchain provides the data with security, and participating users will be verified in the network, eliminating the data's privacy concern [72]. To facilitate cloud computing growth, we can overcome the data's privacy and security concerns by integrating with blockchain technology. It improves data security, service availability, and it can manage cloud data.
