Introducing high-consistent large data cache using active-standby failover

With the development of cloud computing, the key data of the enterprises are in centralized control. Although primary-backup and multi-primary replication are effective way to maintain consistency of the cache, it will become the bottleneck in case of big data. This paper, the bidirectional replication using active-standby failover is proposed to address this issue first. Moreover, the architecture of high-consistent large data cache is presented in detail. Finally, the disaster tolerant and data expansion methods are discussed. Our experimental evaluation on the cache shows the high effectiveness and efficiency of the proposed approaches.
