Alibaba Cloud Storage Gateway
What Alibaba Cloud Storage Gateway is
Alibaba Cloud Storage Gateway links applications running on-premises or in the cloud with Alibaba Cloud OSS buckets. It provides file access through NFS or SMB and block access through iSCSI, so applications can use standard storage protocols without being changed. File gateways keep frequently accessed data in a local cache while OSS supplies storage capacity. Gateways can run in a data center or on Alibaba Cloud; cloud gateways can use ECS instances. Listed virtual machine deployment options include VMware, Hyper-V, KVM, VHD, Qcow2, and Raw.
Administrators can manage gateways from a web console or through an API. Resource Access Management lets them assign specific resource permissions without sharing AccessKey pairs. Data moving from a gateway to OSS is encrypted, and OSS server-side encryption can be configured with a customer-managed key. The service checks data consistency with MD5, logs gateway-to-OSS activity, and provides monitoring metrics. File gateways are compatible with POSIX and third-party backup software. Alibaba Cloud describes uses such as extending local storage, file backup and sharing, access across data centers, and disaster recovery. The service has no free plan. Cloud gateway billing is hourly pay-as-you-go or monthly or yearly subscription; on-premises gateways use a software license, with VM and cache resources supplied by the customer.
Who it suits
It suits organizations that want applications in a data centers or cloud environments to access Alibaba Cloud OSS through file or block storage protocols. It also fits teams extending local storage, backing up or sharing files, connecting data centers, or planning disaster recovery.
