Alibaba Cloud Storage Gateway vs CTERA Enterprise File Services Platform

Alibaba Cloud Storage Gateway connects on-premises or cloud applications to Alibaba Cloud OSS buckets through standard file and block protocols, without application changes. File gateways provide NFS or SMB access, while iSCSI gateways provide block access. Frequently used file data can be cached locally while OSS supplies storage capacity. Gateways run in a data center or on Alibaba Cloud, including ECS instances, with VMware, Hyper-V, KVM, VHD, Qcow2, and Raw deployment options. Management is available through a web console or API. Resource Access Management grants specific permissions without sharing AccessKey pairs. Data transferred to OSS is encrypted, and customer-managed-key server-side encryption is available. MD5 checks consistency; logs and monitoring metrics record gateway activity. File gateways support POSIX and third-party backup software. Use cases include extending local storage, backup and sharing, cross-data-center access, and disaster recovery. There is no free plan.
