Blockchain and Cloud Computing-A Review

Blockchain is a technical breakthrough being investigated by academics and business across a variety of applications, encompassing cryptocurrencies, financial businesses, Internet of things, 5G, risk evaluation, and financial and commercial services. Cloud technology, on the other hand, is ushering in the Digital Realm and quickly becoming the most fashionable topic in IT. Cloud computing, on the other hand, is plagued by a lack of attention, respect, and responsibility. Blockchain, with its innovative characteristics such as autonomy and immutability, adds dependability and authenticity to cloud technology.This research examines the literature on Blockchain-based enterprise solutions published between 2008 and 2021. The following manuscript focuses on the technological integration of Blockchain technology and cloud infrastructure, as well as the current achievements in the field of Cryptocurrency cloud technology. To Be precise, we split the information into three categories: Blockchain employing IaaS, Blockchain employing PaaS, and Blockchain employing SaaS. We’ll start with a look at a few Blockchain characteristics and how they relate to cloud services. Then we provide our study methods, as well as a detailed analysis of important background information. Following that, we describe cutting-edge studies in Ledger storage-as-a-service, strategy creation, computation-as-a-service, data aggregation-as-a-service, microservice-as-a-service, and Acquired by extraction.The report concludes with the current issues in Blockchain based cloud technology, their expected obstacles, and potential studies and opportunities. We believe that research shall give a complete knowledge of the legitimacy of Blockchain based cloud technology and will contribute in the creation of the future cloud computing environment.
