Can customers choose replication regions?
Yes, as of 2026, OCI offers you full control over your replication strategy. You are not locked into "pre-paired" regions; you can choose your own target regions to satisfy specific data residency laws, latency requirements, or disaster recovery (DR) plans.
Here is how the choice of replication regions works across different services:
For your server disks, you can select almost any other region as a replica target, provided you have a subscription to that region.
The "Any-to-Any" Model: You can replicate a volume from Ashburn to London, or from Tokyo to Sydney.
Granular Choice: When enabling replication, the console presents a dropdown list of all your subscribed regions. You can even choose the specific Availability Domain (AD) in the target region where the replica should live.
Latency Check: In 2026, the OCI Console includes an Inter-Region Latency Dashboard. This helps you choose a replication target that is far enough away for safety, but close enough to maintain a low Recovery Point Objective (RPO).
Object Storage replication is highly flexible and "resource-specific."
Bucket-to-Bucket: You create a replication policy on a specific bucket. You then choose a "Destination Bucket" in any other region of your choice.
One-to-One Mapping: Currently, a single source bucket can replicate to one destination bucket. If you need your data in three different countries, you would typically use a "hub-and-spoke" model or a script to trigger multiple copies.
Cross-Tenancy: You can even replicate data to a bucket in a completely different OCI account (tenancy), which is a common 2026 strategy for protecting against "account-level" compromises or ransomware.
A major update in late 2025/early 2026 expanded the replication capabilities for Secrets (passwords, SSH keys, certificates).
Multi-Region Sync: You can now select up to three different regions to automatically sync your secrets. This ensures that if your primary region goes offline, your applications in other regions still have the credentials they need to start up.
| Service | Target Choice | Max Replicas | Key Benefit |
| Block Volumes | Any Subscribed Region | 1 per volume | Instant failover for VMs |
| Object Storage | Any Subscribed Region | 1 per bucket | "Bottomless" DR storage |
| OCI Secrets | Up to 3 Regions | 3 | High-availability credentials |
| Autonomous DB | Any Subscribed Region | 1 (Cross-Region) | Transactional consistency |
To choose and use a replication region, you must meet three criteria:
Region Subscription: You must "Subscribe" to the target region in the OCI Console (it takes about 1-2 minutes to activate).
IAM Policies: You must grant the OCI Service (e.g., objectstorage) permission to "manage" resources in both the source and destination regions.
Subnet/VCN (for DBs): If you are replicating a database, you must have a network path (like a Remote Peering Connection) established between the two regions.
If you are a government or highly regulated entity, OCI now offers Sovereign Cloud Regions (e.g., EU Sovereign Cloud). If you choose to replicate within these specialized realms, OCI guarantees that your data remains within the legal jurisdiction of that specific region, never crossing into the "Commercial" public cloud.
