A Cloud Microservices Architecture for Data Integrity Verifiability Based on Blockchain

The current digital age, mainly characterized by an economy based upon information technology, demands a data integrity service, even more so because organizations and companies are migrating their services over the cloud. This is not simple task; it cumbersome since traditional schemes in databases could be subject to modifications. However, can solved using blockchain technology. paper provides verifiability architecture for cloud systems on blockchain. mechanism store events (as logs) within platform from any system. Users then consult through microservice, acting as intermediate server that carries out set of verification steps blockchain, which confirms previously stored log. Our takes advantage strength concerning integrity, providing traceability track logs. A prototype system case study were implemented proposed architecture. experimental results show decentralized adapted existing born without technology require modular scalable audit characteristic.
