What Are the Differences Between Sharing Images and Replicating Images?
- Sharing images:
You can only share images within a region with other users. To share an image across regions, replicate the image to the target region and then share it. For details, see Sharing Images.
- Replicating images:
- In-region: You can convert encrypted and unencrypted images into each other or enable some advanced features (such as fast ECS creation from an image) using the in-region image replication function.
- Cross-region: Cross-region replication is applicable to cross-region server deployment or data backup. It is often used together with image sharing for cross-region, cross-account image replication.
