Reliability Service Assurance in Public Clouds based on Blockchain

Abstract

The public cloud is a type of cloud computing offered by third-party providers over the public Internet, making them available to Internet users. The public cloud is featured in large-scale, high complexity, dynamic resource change. However, how to provide secure and reliable cloud services to the widest range of Internet users is a big challenge for the development of cloud computing. Blockchain is a new decentralized distributed computing paradigm. The data stored in the blockchain has the characteristics of unforgeability, whole process trace, traceability, openness and transparency, and collective maintenance. Based on these characteristics, blockchain has laid a solid foundation of trust and created a reliable cooperation mechanism. Applying blockchain technology to the cloud computing platform and improving the service quality of the cloud computing platform by using the blockchain mechanism is a research topic with great application prospects.
