BitBill: scalable, robust, verifiable peer-to-peer billing for cloud computing
Li Chen, Kai Chen · 2014
Accounting and billing of cloud resources is vital for the operation of cloud service providers and their ten-ants. In this paper, we categorize the trust models of current industrial and academic cloud billing solutions, and discuss the problems with these models in terms of degree of trust, scalability and robustness. Based on the analysis, we propose a novel public trust model to en-sure natural and intuitive verification of billable events in the cloud. Leveraging a Bitcoin-like mechanism, we design BitBill, a scalable, robust and mutually verifi-able billing system for cloud computing. Our initial re-sults show that BitBill has significantly better scalabil-ity (supporting 10x concurrent tenants using the billing service) than the state-of-the-art third-party centralized billing system. 1
