Blockchain–Cloud Integration: A Survey

Abstract

Over the last couple of years, Blockchain technology has emerged as a game-changer for various industry domains, ranging from FinTech and the supply chain to healthcare and education, thereby enabling them to meet the competitive market demands and end-user requirements. Blockchain technology gained its popularity after the massive success of Bitcoin, of which it constitutes the backbone technology. While blockchain is still emerging and finding its foothold across domains, Cloud computing is comparatively well defined and established. Organizations such as Amazon, IBM, Google, and Microsoft have extensively invested in Cloud and continue to provide a plethora of related services to a wide range of customers. The pay-per-use policy and easy access to resources are some of the biggest advantages of Cloud, but it continues to face challenges like data security, compliance, interoperability, and data management. In this article, we present the advantages of integrating Cloud and blockchain technology along with applications of Blockchain-as-a-Service. The article presents itself with a detailed survey illustrating recent works combining the amalgamation of both technologies. The survey also talks about blockchain–cloud services being offered by existing Cloud Service providers.

Blockchain‐cloud integration: Comprehensive survey and open research issues

“…Table 1 reviews related literature surveys on trust approaches incorporating cloud computing and Blockchain technology. These surveys mainly concern the introduction and integration of Blockchain technology with cloud computing [18], [20], [16] and integrity audit for cloud data [19]. These surveys are chosen according to the following main criteria: we have selected recent surveys published between 2019 and 2022, which deal with topics in the field of cloud integration with Blockchain to strengthen the level of data security.…”

Blockchain technology and its importance for the growth and prosperity of Indian small and medium-sized enterprises

“…It is important for the SMEs to be guided by the GOI through legal frameworks so as to achieve a sustainable growth. Although India leads in terms of development of modern supply chain solutions, compared to China and the US, according to (Khanna et al, 2022), the country is lagging behind China and the US in terms of integrating blockchain and cloud computing technologies, implementation of blockchain-cloud in agriculture, Blockchain-as-a-Service (BaaS), etc. Hence, new policies should be framed to incorporate the BT across a wide range of industries while those firms/individual who take initiatives must be incentivized.…”

Blockchain Revolution in Healthcare: Fostering Applications, Enhancing Security, and Ensuring Data Interoperability

“…Blockchain applications in healthcare need to ensure compliance with regulatory requirements and protect patient data privacy [51,52]. The regulatory environment significantly impacts the adoption and implementation of blockchain technology, requiring a thorough analysis of legal and ethical issues [53,54,55].…”

“…Blockchain solutions are expected to evolve and improve to address the changing needs of the healthcare industry, including the need for secure telehealth interactions, accurate medical histories during emergencies, and patient-controlled health data [57]. There is also interest in exploring the use of cross-chain technology and integrating blockchain with other technologies such as machine learning and the Internet of Things [52,53]. However, there are still challenges to be addressed, such as ensuring regulatory compliance, improving scalability, and addressing data privacy concerns [60,61].…”
