Alibaba Cloud Storage Gateway vs Tiger Bridge

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.

Tiger Bridge is hybrid data-management software for coordinating files across on-premises storage and cloud or other on-premises systems. It presents those locations as a unified namespace and applies user-defined rules to move less-accessed files to cloud, tape, or disk tiers. It can copy files to cloud storage and replace local copies with nearline stubs to reclaim space, and it offers real-time replication to remote sites. Retention controls and checksums support retention and file-integrity validation. The product supports Windows and hybrid deployment, with local caching and edge synchronization. Listed targets include Amazon S3, Azure Blob Storage, Google Cloud Storage, IBM Cloud Object Storage, Huawei Cloud, Backblaze B2, Google Drive, LYVE Cloud, Wasabi, and S3-compatible storage. Scale Up, Flexi-Archive, and Collaborate each list a 200GB minimum commitment; monthly charges are based on the maximum managed capacity tracked in that month. A free 30-day trial is listed. Tiger Technology, which builds hybrid data products for businesses, was founded in 2003 and lists offices in Sofia, Alpharetta, Dubai, and London.
