摘要
Cloud storage is highly available, scalable, and cost-efficient. Yet, many cannot store data in cloud due to security concerns and legacy infrastructure such as network-attached storage ( NAS). We describe Kurma, a cloud storage gateway system that allows NAS-based programs to seamlessly and securely access cloud storage. To share files among distant clients, Kurma maintains a unified file-system namespace by replicating metadata across geo-distributed gateways. Kurma stores only encrypted data blocks in clouds, keeps file-system and security metadata on-premises, and can verify data integrity and freshness without any trusted third party. Kurma uses multiple clouds to prevent cloud outage and vendor lock-in. Kurma's performance is 52-91% that of a local NFS server while providing geo-replication, confidentiality, integrity, and high availability.
