Stardog Cloud Architecture
Below is a diagram depicting the high-level architecture of Stardog Cloud in AWS. 
White-listing Virtual Graph calls from Stardog Cloud
All traffic from a Stardog Cloud endpoint will originate from a single IP address, which varies by the region in which your endpoint is hosted. The Stardog Cloud regions are:
| Country | Region | Domain | IP Address |
|---|---|---|---|
| United States | us-west-2 | produswest2-vg-egress.stardog.cloud | 44.238.183.206 |
| Europe | eu-central-1 | prodeucentral1-vg-egress.stardog.cloud | 52.58.24.147 |
| Australia | ap-southeast-2 | prodapsoutheast2-vg-egress.stardog.cloud | 3.24.173.227 |
Please whitelist the appropriate domain to ensure your Stardog Cloud endpoint can make virtual graph queries to your external data source.
Backup
Enterprise customers can request backup of individual databases to S3 buckets via the Stardog API. The credential for the S3 bucket is stored only during the time the backup is occurring.
Instance-level automated snapshot backups occur daily and are retained for 30 days by default. You may request a restore of a snapshot via a ticket in the support portal. You may also request custom backup schedules and retention periods via the support portal.
