Architecture
The DR architecture for File Server is similar to the Integrations DR topology. It consists of two File Server instances (designated as primary and secondary) in two different cloud regions, which are accessed using a single custom endpoint.
It also includes two public load balancers, one for each File Server instance, that direct traffic from the internet to the respective instances. Optionally, you can use an OCI DNS zone as a front-end to route traffic to the load balancers. The following image shows the architecture in detail:
You must implement CICD to keep the users and folder data synchronized at all times between the two sites. During a failover, you must update the DNS record at your DNS provider or in the OCI DNS zone to switch between File Server instances.
