Integration of Blockchain and Cloud Computing: A Review

Blockchain technology is becoming more popular as it is utilized in various fields, including finance, healthcare, etc., due to its distributed nature, transparency, immutability, security, and auditability. These characteristics make blockchain technology advantageous because it can completely change how data is stored and operations are performed. Cloud computing is a system that stores, manages, and processes data over the internet and on distant computers. It is a form of computing that enables consumers to access data and applications from anywhere in the world with just an internet connection. Cloud computing is a popular centralized system, which is used by companies and individuals to keep and access data online. However, this system is vulnerable to cyber-attacks, data breaches, and other security threats because data are controlled by a single organization and stored centrally. Therefore, research is needed to know the security issues of cloud computing that may be resolved using Blockchain and how Blockchain can be utilized to boost security and integrity. In this review paper, authors have examined how blockchain technology can be leveraged in cloud computing, discussed the advantages of using cloud-based blockchain services, and explored the current trends in this field, paying close attention to its development, advantages, and applications. Several blockchain applications in the supply chain, finance, healthcare, etc, have been explored. Then it comes to some valuable conclusions with few unanswered questions that require more inquiry. This review article offers a broad foundation for researchers interested in cloud data security and data management using blockchain technology.
