Performance Evaluation of a Hadoop-based Secure Cloud Platform

摘要

Cloud computing platforms offer a convenient solution for addressing challenges of processing large-scale data in both academia and industry, beyond what could be achieved with traditional on-site clusters. There are a great number of on-line cloud services, and in the meantime, the security issue is getting more and more significant for cloud users. Whereas Hadoop-based cloud platform is currently a well-known service framework, our goal in this paper is to investigate the mechanisms of authentication and encryption of Hadoop. We try to construct a highly secure Hadoop platform with small deployment cost, robust attacking prevention, and less performance degradation. We also conduct a number of simulations to evaluate the performance under different parametric settings and cryptographic algorithms. Simulation results reveal the feasibility of security mechanisms, and find that the more important thing to construct cloud platforms with appropriate security mechanisms is to consider the application requirements, which could be a better trade-off between security and user requirement.
