A Hybris: Robust Hybrid Cloud Storage Paolo Viotti, Sorbonne Universites,´ UPMC, LIP6 1 Dan Dobre, work done at NEC Labs Europe Marko Vukolic´, IBM Research - Zurich Besides well-known benefits, commodity cloud storage also raises concerns that include security, reliability, and consistency. We present Hybris key-value store, the first robust hybrid cloud storage system, aiming at addressing these concerns leveraging both private and public cloud resources. Hybris robustly replicates metadata on trusted private premises (private cloud), separately from data which is dispersed (using replication or erasure coding) across multiple untrusted public clouds. Hybris maintains metadata stored on private premises at the order of few dozens of bytes per key, avoiding the scalability bottleneck at the private cloud.
