- Problem: We need replication of PNG images to a second region in the same AWS account to improve data durability, and in the case of a disaster, recover 100% of data to the primary region.
- Possible solution: Two S3 buckets need to be configured; one in each region to be completely isolated and avoid sharing the same failure line. For this exercise, versioning must be enabled and cross-region replication (CRR) must be configured.
This diagram shows that an S3 bucket can be found in one of three states:
Let's create an interregional deployment, using two S3 buckets with automatic versioning and replication, to synchronize objects from North America to Europe, just as depicted in the following diagram:
