About the cloud gateway

You can configure Access Appliance as a gateway to cloud storage. You can register cloud subscriptions to your Access Appliance cluster. Multiple cloud subscriptions can be attached, so you need to assign a service name to each subscription. You can then use the service name to attach the subscription to the file system as a storage tier.

If you want to add any other S3-compatible storage, it can be qualified with Access Appliance and used.

The cloud as a tier feature lets you have hybrid storage that uses both on-premises storage and public or private cloud storage. After the gateway and tier are configured, you can use the cloud as a tier feature to move data between the cloud and the on-premises storage. The files in the cloud, like the files in the on-premises storage, are accessible using the NFS, S3, and CIFS protocols. Access to the data present in the cloud tier is transparent to the application.

Before you provision cloud storage, you set up cloud subscriptions. To set up the cloud gateway, you attach cloud subscriptions to your Access Appliance cluster. You need to have the subscription credentials to add the cloud subscriptions. You need different subscription credentials based on your cloud provider.
